2.3 Connector System of Generator

Warnings To prevent possible electrical shock, fire, or personal injury:

• Do not touch any of the connections to the output terminals when any voltage is present.

• Do not make connections to the output terminals when any voltage is present. These voltages can be lethal.

Current cables of generator (for max 120A) use plastic “push – pull” connectors. With these connectors, user simply plugs them into terminals until a click sound is heard. It means that connector is locked.

While pulling out these connectors, they should be released first. This is achieved with pressing gently and then pulling it out completely. With such a gentle push unlocking of internal mechanism happens.

Figure 6 – Current cable connector on the front panel of PTE

Each current phase is equipped with one (mutual) output terminal (red) and two input (black) terminals. The bigger one is designed for currents up to 120A, the smaller one is designed up to 12A but with different maximum power output for small currents (see pictures in next chapter).

Voltage and current connectors are compatible with standard laboratory banana types.

2.3.1 Power Characteristics of PTE (Generator)

Figure 7 - Bigger input terminal - Current

Figure 8 - Smaller input terminal - Current

From these characteristics it is obvious that the high current (“120A~ max”) input is used for direct meters which usually have lower resistivity on current terminals. On the other hand, low current (“12A max.”) input is dedicated for indirect meters which usually come with higher resistivity on current terminals.



2.4 Connector System of Measuring Accessory

Warnings To prevent possible damage, use only accessories and cables supplied by manufacturer of the Product.

Device uses plastic cylindrical push-pull connectors.

Main advantages of this connector system are:

• quick and easy mating and de-mating

• definite and secure locking mechanism

2.6 Description of features Portable Test Equipment consists of two devices: source of measuring signal and Working Standard.

The source is accurate multifunctional and powerful signal generator. Working Standard is an accurate three phase reference meter of electrical quantities. The whole device is dedicated for calibration of electricity meters, and eventually can be used as supply of measuring signals or as reference meter of voltage, current, power and energy.

The device is designed to work in single-phase, two-phase and three-phase connections where signals can be generated with different shapes for various values of parameters and simultaneously measure all characteristic variables including curves and real time values of percentage errors of calibrated meter.

User can set characteristics of generated signals in a simple user interface of generator mode and in measuring mode measurement results are displayed in real time. The results are stored in an internal database, from where, using the USB bus, can be transferred into the PC. Measurement and evaluation values are implemented in all phases separately and also cumulative.

Measuring section either displays characteristics of generated signal or allows via versatile interchangeable inputs connection of different external meter accessories: current transducer for small currents up to 20 A, current clamps for currents up to 120 A or 240 A, flexible current probe for high currents up to 6000 A or voltage transducer for voltages up to 500 V (phase to neutral).

Measurement based on accurate A/D conversion and DSP technology enables high-speed evaluation of all main and descriptive variables in real time. In addition to measuring power, voltage, current and phase device also indicates the phase sequence, evaluates active, reactive and apparent energy. The apparatus measures and graphically displays distortion and shape of measured signals. For calibration purpose the device is equipped with frequency output, for which any variable and frequency constant can be set.

The appliance is equipped with integrated error processing capability, with optical sensor for capturing LED, disk or impulse contacts of verified meters and snap switch for simple manual verification.

The device is powered externally from 230V. Software for MS Windows allows transmission and presentation of measurement data in PC.

2.7 Generator

Warnings To prevent electric shock or personal injury, remove all cables from the terminals that are not used. When connections are made to a circuit that can be energized with voltages, always ensure there are no external voltages present before connecting to the Product. Voltage can be present at the loose ends of cables.

Caution

To prevent damage to the Product, do not connect mains power to any signal input or output terminal.

The basic function of the device is generating signals. The periodic sine wave is used as standard signal. Generating of Burst Fired and Phase Fired which are defined by the norm is also comprised in default configuration. In addition to these three options, the user can define own harmonic composition of signal with individual setting of amplitudes and phases of separate harmonic content of signals. Generator section in the SW uses green headers.

Starting of signal generation is achieved by red button which is located in the left bottom corner of the keypad. Start and stop mode is always active, regardless of the currently displayed screen. If generating is active, there is small colored square indication, which is located in the right top corner of the display next to the clock. Orange square is briefly displayed at the beginning and end of each generated signal and represents rise time and fall time of signal. If the square is filled with red color stable generation is in progress. Alternative indication of generation is also a beep (but it has to be enabled in generator settings).

To switch between screens of generator and meter serves the green button located in the right bottom corner of the keypad.

Generator remains active even if there is some screen of measuring section currently displayed. Or vice versa, i.e. measurement remains active even if the user switches to the generator section.



3. How to Use the Appliance

Warnings

The Product can supply lethal voltages. Do not make connections to the output terminals when any voltage is present. Placing the instrument in standby may not be enough to avoid shock hazard. Disconnect the RS232 and USB cables from the Product to prevent remote commands setting unexpected outputs.

To prevent electric shock, make sure the Product is grounded as described in Chapter 2.

Caution

Product must not be left unattended when in operation. Authorized personnel must be present all the time the product is being used on site or in laboratory.

1. Prepare any electricity meter, you want to verify. 2. Connect the power cord to the device and plug into the wall socket. 3. Connect current and voltage cables to the meter (DUT), for various connection situations see

chapter 7 APPENDIX. 4. In case that measurement will be realized with external measuring accessory (e.g. voltage and

current transducer), connect this accessory before PTE being turned on. After switching on the device this accessory will be properly detected.

5. Turn on the PTE. The device after start automatically shows the initialization screens and moves into the generator section of SW, namely the Basic screen of generator. Detailed description is in chapters 3.1 and 3.2.

6. If Basic screen of generator (see Fig. on page 18) contains required parameters, you can begin

to generate a signal with button on the bottom left. If parameters change is needed, so do it. Proceed as described in chapters 3.2 to 4.3.

7. While generating your chosen signal switch to the measuring section by key in bottom right. There is a description of all measured values in chapter 5.1.

8. Before generation of signal, or even during, you can save given meter to the database referred to all its parameters. To enable this function switch to Measuring Mode - (F5) Settings - (F4) Database. Description of databases is in chapter 0.

9. To perform verification of energy dosing follow chapter 5.2. If you need to perform basic meter error test follow the description in chapter 5.3.

10. For further measurements, such as transformer check proceed with chapter 5.4. Detailed description of generator section is located in the following chapters.

* Screen identification codes (for example * P42) can be found in captions of all described software screens

DUT = Device Under Test



3.1 Initialization

Device Initialization screen * P118

Date & Time Adjusting screen * P119

Device Initialization screen is shown after switch-on of the device. During initialization it detects all connected accessories (voltage and current probes have to be connected before turning on). Appliance loads parameters of sensors from their memories only during device initialization.

Note: In case when device’s date & time are incorrect (outside of limit) then Date & Time Adjusting screen is shown and user has to set correct date & time.

After initialization device switches into Generator mode and shows Basic generator screen.

3.2 Basic Screen of Generator

Warnings Do not touch the output terminals of the Product even if the display shows the presence only non-lethal voltages or currents. There can be present lethal voltages or currents due to error or connected meter.

After initialization screen device automatically displays the basic screen of generator after a short while. In this screen it is possible to easily change following parameters:

- voltage and current for each phase - phase shift of voltage and current for each phase - frequency value - type of connection (3f device only) - fixed or user-defined signal



Basic generator screen 3f device * P101

Basic generator screen 1f device * P124

To move the cursor on the screen, use the keypad arrow keys and OK button changes and confirms

values. With a Shift key user can change all values in a row. Shift highlights specific row, OK enables edit mode and written number will be copied into adjacent fields. Afterwards OK key saves values.

Phase shift can be defined also by Power Factor on a special screen, which is accessible from basic generator screen by Exp button. This screen allows to set power factor value, sine or cosine, Lead or Lag. After confirmation by F5 the display will switch back to the basic generator screen and the power factor will transform into respective angles, presented in the table and will be used during load point generation.

Screen of Power Factor definition * P149

Changing of connection is immediate. Upon confirmation, for example it changes the number of displayed phases; see the examples in table below.



Basic generator screen with changed connection type* P102

Basic generator screen with changed connection type* P105

When all necessary parameters are set, it is possible to initiate signal generation with a start

button . The same key serves for termination. When changing any parameter, it is highlighted in red. These changes are not stored in memory. They are saved only when the generation starts, and then the red color of changed data turns black.

For start generating, from any screen, always last saved values are used. The same applies after power on.

In case that is needed to change other parameters of generation, which are not included in the Basic screen of generator, it is possible to use the function keys:

F1 ........... it starts and ceases signal generation

F3 ........... it opens a menu of available signals – screen “Signal Shapes”

F4 ........... it opens a menu of automatic run of predefined tests – screen “DB Measurements”

F5 ........... it allows changing the settings of generator section Exp ................. it opens Power Factor screen

3.2.1 Error in generation

When error in generation occurs, device automatically skips to Standby in corresponding channel. Standby means that generation in particular channel is suspended. Once the error cause has been removed, generation update is possible, usually with F2 button. However, if voltage error occurs, it is necessary to stop and run again the generation.

Typical situation: current loop has been malfunctioned so the generation in respective channel is suspended. Error (red notification in main generator screen) in given channel occurs, i.e. no current generation in that phase, however voltage remains untouched. After current loop examination and reparation, the generation shall be restored by F2.

Conclusion: Meter remains under power (voltage) through the whole time.



4. Extended Generator Options

4.1 Signal Shapes You can get into Signal shapes screen by F3 from Basic generator screen or from Generator settings, item no. 2.

Signal shapes screen * P106

There is a list of available signals at the top of screen. The first six are default and unchanging, based on standards. Other ones can be modified by user, and also can delete and add new signals. Under this list all channels are listed and highlighted are those that are used in signal at current cursor position. In the bottom half of screen is a curve which describes the signal waveform at cursor position. Signals are generated in terms of harmonic composition. User selects which harmonic item will be a part of which signal, also selects their share in percentage compared to 1st harmonic, phase and channel in which the signal will be displayed. Image on the left in the table below shows the window for editing user signal. Screen at bottom right illustrates the channel selection for a particular signal. In the editing table the cursor moves with arrows of keypad and pressing OK confirms and changes values. Applying to individual channels is determined by a square, where black means it will be generated and white it will be not generated to a particular channel.

Integration time is a modifiable parameter - see Time base parameter in chapter 5.8.1 Measurement Settings.

4.3.2 Inputs Configuration

Inputs Configuration Screen * P150

This screen allows switching between several measurement inputs.

1. Generator U and I This is the only option here, which allows the user to enter the basic Generator screen (like depicted in chapter 3.2) to set all possible parameters (related of generating power). After pressing OK when the cursor is located on item no. 1 the basic generator screen appears. Blue screens show load values (U, I, energy, power, meter error measurement possible, etc.)

2. Ext. [In A] & Internal U In this option external accessory connected to input A and internal voltage are selected to be measured together. User cannot change generated parameters; all changes are possible only when item no. 1 is selected in this menu. However, Generator can be in running state if it was started previously. In this option only this screen is shown to the user from all generator’s screens (green ones).

When this option is pressed main blue screen appears with regards of used accessory. If connected accessory is for voltage measurement; U+U screen is shown, otherwise it is the Load Values screen.

3. Internal I & Ext. [In B] In this option external accessory connected to input B and internal current are selected to be measured together. User cannot change generated parameters; all changes are possible only when item no. 1 is selected in this menu. However, Generator can be in running state if it was started previously. In this option only this screen is shown to the user from all generator’s screens (green ones).



When this option is pressed main blue screen appears with regards of used accessory. If connected accessory is for current measurement; I+I screen is shown, otherwise it is the Load Values screen.

4. Ext. [In A] & Ext. [In B] In this option only values via external accessories are being measured regardless of generated power. User cannot change generated parameters; all changes are possible only when item no. 1 is selected in this menu. However, Generator can be in running state if it was started previously. In this option only this screen is shown to the user from all generator’s screens (green ones). When this option is pressed main blue screen appears with regards of used accessory.

5. Phantom Load This is a unique option in this menu. Principally Phantom Load enables to generate current into existing load (voltage remains intact). That’s why only current related parameters can be changed in this screen. This screen can be opened only if voltage measuring accessory is connected into input B of the device, otherwise error message appears! In the top user can set amplitudes and phase shifts for all phases of current. Phase shift is related to the voltage which is being measured by the accessory. Measured voltage and its phase shifts are visible in the bottom part of this screen. They are read only as well as the frequency in the middle. User can also change the connection type 3P4W, 1P2W, etc. and the shape of signal (see chapter 4.1 on page 21).

ΣS ........... Sum of Apparent Powers

cos φ, sin φ ............ Power Factor

EP............ Active Energy

EQ ........... Reactive Energy

ES............ Apparent Energy

ΣEP ......... Sum of Active Energies

ΣEQ ......... Sum of Reactive Energies

ΣES ......... Sum of Apparent Energies

f ............. Frequency

L1xx ...... Voltage Phase Sequence (L123 or L132)

LI1xx ...... Current Phase Sequence (LI123 or LI132)

Control keys:

F1 ... Graphical Presentation screens

F2 .... Dial test

F3 .... Stop / start online energy accumulation

F4 .... Clear energy registers

F5 ... Menu

Online energy accumulation - Sum of Energies (resp. Powers) accumulate values from the beginning automatically. With F3 button it is possible to suspend/resume accumulation. When Dial test screen is accessed these registers will be cleared but only if Test Initialization has been carried out (see next chapter).



5.2.2 Dial Test

This page can be accessed from Load Values screen by F1 followed by F2 or from Energy Values screen by F2 or F5 Menu, point 6 Test & Calibration, point 3 Dial Test.

Configuration of Dial tests is in Test Settings menu, where mode (Time or Energy), amount of time / energy and energy type (Active, Reactive, Apparent) is specified.

When Generator (PTE) has dosage feature enabled (see chapter 4.3.1 Generator Settings) Dial test automatically controls also start and stop of power generation. When dosage is active (energy is being accumulated with real-time generation) red highlighted “Dosage” message flashes on each screen.

Test is started with F1 key. After first press initialization occurs and dial test is prepared. At this stage #1 field (see picture below) should be filled with initial state of register of electricity meter.

After second press of F1 key testing begins. If the Generator section is enabled for Dosage, generation of current and voltage starts automatically.

After third press of F1 key the testing is aborted by user. If the Generator section is enabled for Dosage and “Stop voltage” (and /or current) is also enabled Generator will also cease generating this quantity (U and /or I). After that user can fill #2 field (see picture below). Then Error is calculated.

If the user will not interrupt the testing by third press of F1 key PTE will terminate testing automatically after reaching certain value of energy or time (depends on Test settings).

Note: Before first initialization (right after Dial test screen is opened) it is recommended to generate voltage (only) to have such meter under power. This is useful especially for static/electronic meters so user is capable of performing initial register reading. When Dosage starts (second F1 press) PTE automatically generates U and I. For activation of simultaneous measurement of P/Q/S energy testing set correct method. (F5 Menu, F1 Measurement Settings, page 3/6, ENERGY MEASUREMENT)

COUNTERS Section: This section is related to the values obtained from meter. Meter connected to the network can measure quantities via transformer. In such case meter’s parameters can be defined for transformer’s secondary side (Sec.) or calculated to the primary side (Prim.).

Operator enters initial state of meter counter #1 before test and final state of meter counter #2 after test. Device automatically calculates difference (ΔE) and evaluates test error. It is also possible to define directly the difference (ΔE).

Energy measurement Section:

This section is related to the energy measurement obtained by device. CT (Current) and VT (Voltage) ratios are acquired from database. In this window they can be changed (they turn red). By default, both Prim. / Sec. switches are set to the same value which is associated to database item.

These switches along with CT / VT ratios enable to set where the meter is placed (during measurement) and where the device measures energy.

Running in Automatic Mode (chapter 4.2.3 on page 27) uses also this mode, which means that during dial test in Automatic Mode (defined on green screen) actually this Dial test runs in the background on the blue screen and also all fields are filled. In such scenario fields #1 and #2 are filled automatically (if optical communication head with static meter is used) or manually – user must switch into this screen and fill #1 at the beginning and #2 at the end of dial test.

Dial Test runs always simultaneously with Maximum Demand Test which has to last longer than Dial Test. The reason lies in principle of Dial Test evaluation. This feature offers also evaluation of these two tests concurrently.

𝑈. 𝐼. 74000. 𝑡𝑖𝑚𝑒

Then, for instance with range of accessory 500V/120A and dosing only 0.1A (230V) for 60s, it causes an error of 0.059%. With higher current or with more time the error directly proportionally decreases. This behavior is caused by lower resolution for small currents disregarding other errors like device accuracy.

Conclusion: Dose more power for longer time (several minutes)!



5.2.3 Maximum Demand Test

This page can be accessed from Load Values screen by pressing of F1, followed by F2 and F3.

Configuration of MD tests is in Test Settings menu, where Period, Subperiods and Window can be specified. The duration of MD test is identical with Dial test duration and it is recommended to be at least two times greater than period of MD test.

Test is started with F1 key. Then the Energy (E) is being summed and the average power (MD Act.) is being calculated. Operator must be aware of the number already stored in electricity meter’s Maximum Demand Register. It is highly advised to delete such meter’s register before and after MD test. This operation will ease the whole test procedure.

During MD test the icon above F1 depicts the sign of play. In this state the test can be prematurely stopped by F1 and the icon changes to stop sign. To evaluate the MD test, it is compulsory to wait until the test stops automatically or at least wait until the time “End” passes because only then the “MD Reg.” will obtain value different from zero. This is the value which is compared with the meter’s MD register. When the test is ceased, “Enter MD register” message flashes until any key is pressed. This warning informs the operator to submit the value of MD register from meter. Then the overall MD error is calculated.

Dial Test runs always simultaneously with Maximum Demand Test which has to last longer than Dial Test. The reason lies in principle of Dial Test evaluation. This feature offers also evaluation of these two tests concurrently.

Meter connected to the network can measure quantities via transformer. In such case meter’s parameters can be defined for transformer’s secondary side or calculated to the primary side (upper switch – Sec / Prim). By default, both Prim. / Sec. switches and CT/VT ratios are acquired from database. They can be changed (they turn red). These switches along with CT / VT ratios enable to set where the meter is placed (during measurement) and where the device measures energy.

Content:

U, I ............... Load point values

Parameters... Parameters of tested meter

SN ................. Serial number of meter (asterisk behind the SN indicates that at least one from above parameters is different from meter parameters defined in database)

Error ............ Actual measured error of meter

Samples ....... Number of measured/required meter errors

Impulses / Integration time ............. number of pulses (with time) which make one sample

Average ........ Average error

Deviation ...... Standard deviation of measured samples

Parameters of tested meter:

Connection type ............. 3P4W, 3P3W, 2P3W, 1P3W or 1P2W (see Connection Diagrams) Energy type .................... Active, Reactive or Apparent Registration mode ........ LED, DISC/SO (SO = pulse output of meter), SNAP. S (=snap switch).

Switching into DISC/SO causes permanent shine of transmitter LED of OPTS 2100 sensor, so the user can easily set the position of OPTS 2100 before calibration (more information in Accessories Guide Chapter Optical Sensor)

Constant ......................... Constant of tested meter Constant Unit ................. i/kWh, i/Wh, i/Ws, i/kWs, kWh/i, Wh/i, Ws/I, kWs/i, MWh/i or i/MWh

settings). Changing this value influences the change of Constant value. VT ................................... transformation ratio of voltage transformer (can be hidden in Test

settings). Changing this value influences the change of Constant value.



Constant type ............... Primary / Secondary – for indirect meters in the database, indicates which side of the connection view to transformer is referred the constant of electricity meter. For direct meters the default value is always Secondary and in that mode this parameter is not displayed. With parameter change the constant is automatically converted under CT VT transformation ratios stored in database for actual meter.

With changing the parameters CT Ratio, VT Ratio and Constant type the Constant parameter is automatically recalculated in the Meter Error Test screen and used in subsequent tests. When user changes the Constant type back to the value according to database item associated to that meter, Constant value is set to default for this meter type. It means CT and VT ratio parameter values are ignored in Meter Error Test screen. If CT or VT has been changed, Constant type value has to be toggled to opposite (against database) to reflect the Constant value modification.

In a case, that this mode is activated from Database, then the Parameters are set according to the selected meter. If this mode is activated from Load Values screen the Parameters are set according to the Measurement Settings.

Navigation between parameters can be done by ▼▲ arrows, parameter selection can be done by OK key and changing of parameter’s value can be done by ◄ ► arrows. If any parameter has been changed, it become red. It means that default value has been modified. These parameters remain modified until next enter to Database screen. Entering the Database will set default parameters of corresponding meter.

F4 key which is available after performing meter error test saves test result (including load point info, signal shapes and harmonics) into results database for currently selected meter.

REACTIVE POWER MEAS ..... Setting of reactive power measurement

Method ........................ Measurement method: True, Cross, Shift or Fund. f. Remark: method Fund. f. is available only from firmware v. 5.69

Description of supported reactive power meas. methods:

True … classic calculation: 𝑄 = √𝑆2 − 𝑃2. The sign is determined by reactive power calculated from Shift method. This method’s result is considered by IEEE 1459-2010 as nonactive power. IEEE 1459-2010 defines only nonactive power and fundamental reactive power.

Cross … calculation from artificial connection:

𝑄 = 𝑄1 + 𝑄2 + 𝑄3 = (√3 ∗ 𝑈23 ∗ 𝐼1) + (√3 ∗ 𝑈31 ∗ 𝐼2) + (√3 ∗ 𝑈12 ∗ 𝐼3)

Rem: The system must be balanced for achieving correct values! This method is valid only in 3-phase connections with phase sequence L123. In 3-phase system with phase sequence L132 this method calculates results with opposite sign.

Shift … calculation from U and I where current is shifted by ¼ of period in time domain: 𝑄 = 𝑈 ∗ 𝐼′. This approach is mentioned in Annex A of IEEE 1459-2010. Rem: Method does not consider higher harmonic components correctly!



Fund. f. … reactive power defined by IEC 62053-24 is reactive power of fundamental harmonic component. This type of reactive power is also defined in IEEE 1459-2010 as fundamental reactive power: 𝑄 = 𝑈𝑓𝑢𝑛𝑑 ∗ 𝐼𝑓𝑢𝑛𝑑 ∗ sin 𝜑𝑓𝑢𝑛𝑑 Rem: Method affects calculation of all units (voltage, current, active power, apparent power etc.)!

Every meter (shown in DB 1/5) can have stored more measured meter errors (DB 2/5), stored load point values (DB 3/5), results of Dial tests (DB 4/5) and readouts (DB 5/5). All test results and load values are always saved together with harmonics and signal shapes.

Database of Meters * P05

DB of Meter Errors* P06

DB of Load Values* P75

DB of Energy tests* P76

DB of Meter Readouts * P15

Navigation in database screens In screens where more separate tables or components are shown in one page the selection of table is done by using arrow keys and confirming by OK. In selected table the items (rows) can be browsed by arrows and page down/up keys. Pressing OK in any table closes browsing in that table and selects whole table which enables to switch to other part of the screen. Last selected item in table of meters (DB 1/5) becomes selected meter and is used in other screens. Selected item in top table is always highlighted with yellow color. Parameters of selected item are showed in bottom table.

Searching in database of meters Searching for meter or selection of some group of meters can be done by inputting search string into one or both searching fields SN (serial number) and TYPE (type of meter) and confirming by OK.

6. Remote Interface

6.1 Connection to PC USB Communication Cable type A-B is required for connection of device to PC’s USB port.

USB cable type A-B

Communication Driver required by Windows XP or higher is

FTDI Virtual COM port (VCP) driver (Not Microsoft WHQL certified)

Driver is present in CD supplied with device – typically in DRIVER_USB subdirectory. Driver can be found also in internet: Newest version of required driver is available from FTDI website:

http://www.ftdichip.com/Drivers/VCP.htm

Maybe not actual but tested version of driver is available in Applied Precision’s website from link:

http://www.appliedp.com/download/driver/ftdi-vcp.zip

Driver Installation - If windows ask for driver … navigate to driver subdirectory on supplied CD - If driver downloaded from internet … unpack the zip file and install included executable file

COM port New virtual COM port will appear in operating system after each connection of the device to PC if driver is correctly installed. Presence of this COM port can be checked in Device Manager of Windows.

Device Manager

COM port number (for example COM7) has to be chosen in all PC communication software for correct operation.

http://www.ftdichip.com/Drivers/VCP.htm

http://www.appliedp.com/download/driver/ftdi-vcp.zip



6.2 Firmware Upload Firmware (=Device Software) can be upgraded using software utility Firmware Upload - USB available on supplied CD (typically in directory \PTE\SERVICER) or from internet link: http://www.appliedp.com/download/software/servicer/fwuploadusb/fwuploadusb_sw.zip

Firmware Upload - USB is single file standalone utility which doesn’t require installation.

Firmware Upload – USB utility

Firmware package is supplied as zip archive (typically with name pte_fw*.zip). Don’t unzip the file! Firmware zip file name has to be inputted (browsed) into Firmware Upload - USB utility directly.

Firmware upload process: 1. Connect PC to device and switch-on the device if not done yet 2. Start Firmware Upload - USB utility (newest available version if possible) 3. Select correct COM port in Port panel (and configure it’s settings if not same as in devices) 4. Select device type PTE in Device panel

5. Test communication with the device using read button in Device panel 6. Browse for firmware zip file into the File Name field 7. Select parts of firmware package / functions which should be uploaded / executed 8. Start firmware upload using Start button and wait until whole upload process finishes

Important remarks:

• User can be asked to restart the device before Primary device firmware (second item) upload.

• Internally stored measured results are deleted only when Format (fist item) is selected.

• Full upgrade (first item selected) is recommended if any problem with the device and on every major version upgrade (1.xx ->2.xx, 2.1x ->2.2x ...)! In this case be sure that all measured results were downloaded into PC software before full upgrade.



6.3 Remote Communication

Device control, results readout and measured values collection remotely is performed using device commands compatible with SCPI standard (Standard Commands for Programmable Instruments).

Main rules of SCPI standard:

• parentheses { } restrict parameter in the command strain

• parentheses [ ] restrict optional parameters or parts of commands

• parentheses <> restrict parameter, which is due to be replaced by the value

• perpendicular line ( | ) separate options, from which exactly one has to be chosen

• character case in the command is optional (command SYST:VERS? is identical with sYsT:VeRs?)

You can use the USB interface as well as the RS232 interface to send the commands. Each command

must be ended with <CR><LF> resp. <EOL> (\r\n) signs (e.g. *IDN?<CR><LF> ), otherwise the device

does not respond! The default port setting values are following: BaudRate – 57600, DataBit – 8, Parity – None, StopBit – 1. For sending the SCPI commands you can use the AP Terminal utility, which you can find in the Servicer subdirectory of your PTE installation.(called Terminal.exe), see figure below.

7.2 Aggregate Energy Calculation Methods



7.3 Overvoltage Categories

7.4 Accuracy Verification Since the PTE is a Working Standard (Portable Reference), it offers a possibility to verify its accuracy by another reference (e.g. more precise one). For such a scenario, the PTE is equipped with BNC connector, which generates pulses according to measured energy. AUX connector can be also switched into such mode. This provides more options regarding connection capabilities to external reference.

7.4.1 How to carry out the Accuracy Verification?

Use external reference as a load and connect the PTE to the reference with regard to voltages and currents. Lastly connect BNC connector to the pulse input of the external reference. In such scenario, the reference will measure the same power as the PTE and PTE’s pulses will be measured by reference’s pulses input (acting like regular electricity meter).

Optionally a supplied cable reduction can be used to utilize the AUX connector as pulses output (AUX output in Measurements Settings has to be enabled (ON) for such functionality).

Optionally a pulses divider (supplied by Applied Precision) can be used to lower the pulses rate if the PTE’s constant modification is not enough to fulfill the possible reference’s maximum pulses limitation that may be present (e.g. with older reference standard).

Instead of BNC or AUX output connector, the metrology LED of PTE can be used in a same way as any regular electricity meter, i.e. with specific sensor.



7.5 Measurement Time Measurement Time (time needed for new sample) is defined by Integration Time, which is stated in Test Settings of device.

If time between marks / impulses from the meter under test is longer than Integration Time then Measurement Time is equal to time between capturing marks from the meter.

7.6 Measurement Error Measurement Error Limits (tolerances of precision) in basic load points and temperature 23 °C are defined in technical specification. Measurement Error Limit for power measurement in other load points and temperatures is:

( ) TEMPPHASEAMPLDEV LIMITLIMITLIMITLIMIT ++22

LIMITDEV ............... overall device error [in %]

LIMITAMPL ............. amplitude error [in %] (defined in technical specification)

LIMITPHASE ............ phase error [in %]

LIMITTEMP ............. temperature error [in %]

Calculation of phase error for active power:

7.7 Maintenance The PTE is cooled by variable-speed fans. To get the most reliable performance, ensure proper air flow for the Product.

Caution

To guarantee correct operation of the PTE:

• Do not block the vent openings located at the front panel.

• Do not operate the Product in a dusty environment.

• Inspect and clean all vent openings at least once a month.

• Do not let liquids enter the Product through the vent openings.

• Do not use the Product outside its operational temperature range.

• Ensure that all cables are in good condition.

• Use special (included) plugs that make a firm, secure connection to the Product’s output binding posts. This is especially true for the current terminals, which can output 120 A and cause self-heating with loose fitting plugs.

• Inspect the output binding posts prior to use. Repair loose output binding posts before use.

• Do not overload the output by leaving the Product switched on with the load connected for a long time, especially on 120 A current range and 300 V voltage range.

• If instruments to be calibrated are not connected to the Product output terminals with the original test cables, ensure that cables suitable for the calibration adjustment voltage and current are used. Maximum output voltage can reach 300 V ac and the maximum output current can reach 120 A ac.

• Do not use the smaller black output current terminals for currents greater than 12 A. They are intended for indirect meters only

7.7.1 Regular Maintenance

The PTE does not require special maintenance of electrical or mechanical parts. Inspect the output binding posts for wear and any loose connections. The case and the display can be cleaned by a microfiber cloth rag moistened with alcohol. The PTE should be verified at the recommended two years’ interval.

7.7.2 Clean the Product

Caution

To prevent damage to the PTE, do not use aromatic hydrocarbons or chlorinated solvents for cleaning. They can damage the materials used in the PTE.

For general cleaning, first disconnect all power input and signal cables. Wipe the PTE with a soft cloth dampened with water or a non-abrasive mild cleaning solution that does not harm plastics.



7.7.3 Fuse Replacement

There are two user-replaceable fuses in the PTE, the mains power cord fuses. One is for L and the other for N wire. To replace these mains fuses:

1. Switch off the PTE. 2. Remove the mains power cord from the mains connector at the front panel. 3. Insert a flat-head screwdriver into the opening that is on the mains switch and pull out the fuses holder. 4. Remove the fuses and replace them (always both) with new fuses of the correct rating (see power cord plate). 5. Replace the fuses holder. 6. Replace the mains power cord.

7.7.4 User-Replaceable Parts

The PTE contains no user-replaceable or serviceable parts.
