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.

2.6 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.

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 5.8.
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

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

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.

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.
