4.3.12 Zero Calibration Function for Measured Current
Values
When the PD03M-PCR-LA and PD03S-PCR-LA options are used to
perform master-slave 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 VA displays, and the analyzed har-
monic current value, which are related to current measurements. In
this case, use the Remote Controller as described below to perform
zero calibration.
Zero calibration operating procedure
In addition, be sure to read the Operation Manual of the PD03M/S-
PCR-LA.
1. Press the ESC key to select the Home Position.
2. Press the (SHIFT, MODE) keys.
3.
Press the F1 key. This starts zero calibration, and the following
display appears on the display unit.
When zero calibration ends several tens of seconds later, the fol-
lowing display appears on the display unit.
4. Press the ESC key to exit the zero calibration mode.
The calibrated value will be stored in the PCR-LA power supply.
However, re-calibration must be performed, depending on
changes in ambient temperature and the like.
