Single Phase or Three Phase Comparator
Primary Standard with Accuracy Class 0.01
COM1003/COM3003
The System
Concept
Comparator COM1003/COM3003 is part of the
ZERA high precision measuring instrument
series. To meet the requirements a single phase
COM1003 or a three phase COM3003 is
available.
As AC/DC transfer standard comparator serves
for testing current and voltage meters as well
as single phase or poly phase* power and
energy meter testing systems in metrological
institutes, official testing places and other
testing fields of energy suppliers or
manufacturers of electricity meters.
Via soft keys, 6.4 colour display and
integrated user software MT3701 inputs,
measurements and visualisations will be
performed during the operation. An additional
external control including evaluation and report
generation is achieved via windows based user
software SSM3000 and external Windows PC.

User Software
Data management
Individual functions of the integrated user
software are described in the following.
Measurement data can be stored on an
especially configured USB stick.
For evaluation and reporting of the measurement results data management software MTVis
can be used on external PC.

Actual Values
Measurement
The following system parameters are displayed
as averages values over an adjustment
integration time:
- RMS values of phase voltages and currents
and their DC component
- All angles between currents and voltages
calculated from the fundamental components
- Active, reactive and apparent power, per
phase or total
- Frequency and direction of rotating field
Vector Display
Actual values can be displayed in table form or
as vectorial graphic.
Waveform Display
The waveforms of voltage and currents can be
measured and displayed. The user can choose
between display as curves with indication of
individual values and harmonic displaying with
individual distortion values.
Error Measurement
Static and electromechanical power meters as
well as all kind of measuring instruments with
power proportional frequency output can be
tested in the menu “Error measurement”.
The user can select between scanning head
input or frequency input.
Harmonic
Measurement
Harmonic spectrum measurement in voltage
and current up to the 40th THD conforming to
EN50160. The harmonic spectrum can be
displayed in a chart or in a diagram. All
measured harmonic values can be stored
according to the customer information data on
USB stick. The system has also the ability to
scan the measured harmonic by using a cursor
and to display the scanned values referring to
the cursor position on the screen.
