5-6 Single-phase Parallel Operation
OT01-PCR-LA/2
5.4
Ammeter’s Zero Calibration Function
When the PCR-LA power supplies perform parallel operations for the
fi
rst time,
there may be an offset (indication of a slight value under no-load conditions) in the
current, power, power factor, and apparent power indications, and in the analyzed
harmonic current value, related to current measurements.
In such a case, RS-232C Control or one of the following options can be used to per-
form zero calibration. The zero calibration function works even when a load is con-
nected. However, to ensure accurate calibration, perform zero calibration with no
load connected.
■
One of the following options is required:
• RC04-PCR-LA (Remote Controller)
• IB03-PCR-LA (GPIB Interface)
To ensure accurate measurements, wait more than 30 minutes after turning the
PCR-LA power supplies’ POWER switches ON. Then, perform zero calibration
immediately before starting measurement.
■
Settings on the PCR-LA power supplies
Make the following settings
fi
rst when using either option.
■
The PCR-LA power supplies retain calibrated values.
Once zero calibration has been performed, the PCR-LA power supplies retain the
calibrated values during operation (as long as the connections remain the same).
