Calibrating Meters and Transducers
with the Arbiter Systems 1040C
Panel Meter Calibrator
Introduction
Because of the variety of parameters
involved, in-house and field calibration of
meters and transducers used in the power
industry has in the past required several
specialized instruments. The Arbiter
Systems Model 1040C Panel Meter
Calibrator has incorporated all of the
necessary functions into a single portable
unit, designed specifically for the task. The
purpose of this document is to provide a
guideline for using the 1040C to calibrate
commonly used meters and transducers.
The 1040C Panel Meter Calibrator is
used by service and calibration professionals
in the power generation and distribution
fields, to measure and/or insure the accuracy
of various meters and transducers used in
generating facilities and substations. The
instrument is also used by the U.S. Navy, to
perform similar calibrations on equipment
used for shipboard power generation and
distribution.
The 1040C Panel Meter Calibrator can be
configured to perform eight calibration
functions:
-Voltage (ac and dc);
-Current (ac and dc);
-Frequency;
-Power;
-Power Factor;
-Phase;
-VARs;
-Synchroscope.
A front panel keyboard and display allow
direct selection of values for all of the
parameters shown above. Entered values can
be further modified using a knob also located
on the front panel. A percent deviation key
provides a simple method of determining the
percentage of error for the meter or
transducer under test. An internal memory
allows storage of up to 99 instrument
configurations for repetitive calibration tasks.
Many of the operations performed via the
front panel can be duplicated using the
included hand-held control unit. Devices
which operate within the following ranges
can be calibrated with the 1040C:
-A.C. Voltage:
1.5 Vrms to 750 Vrms.
-A.C. Current:
0.1 Arms to 7.5 Arms.
-D.C. Voltage:
0.01 Vdc to 1000 Vdc.
-D.C. Current:
0.1 mAdc to 10.5 Adc.
-Frequency:
50 Hz to 75 Hz, 333 Hz
to 500 Hz.
-A.C. Power:
1.5 VA to 5625 VA.
-Power Factor:
0.0 to 1.0, lead or lag.
-Phase:
+180 to -180 degrees.
-VARs:
1.5 VA to 5625 VA.
-Synchroscope:
Selection between 0 and
180 degrees.
