The Arbiter Systems®
Inc. Model 1040C and 1040CU Panel Meter Calibrator (PMC) integrates
eight calibration functions: voltage, current, frequency, power,
power factor, phase, reactive power (VARs), and synchroscope into
one compact portable package. The units are designed to easily
calibrate virtually every type of panel meter and many transducers,
circuit breakers and overcurrent relays. Model 1040C includes a
hand-held control allowing operation at a distance when calibrating
panel meters in the control room substation.
The Model 1040C's precision AC/DC voltage and current sources may
operate independently to calibrate voltmeters, ammeters, and
frequency meters, or together to calibrate watt meters, watthour
meters, power factor meters, VAR meters, and phase meters.
