CALIBRATION
4.1 INTRODUCTION
This chapter contains calibration procedures for the P62, P63, P66, P83, P86 and D3
Series.
4.2 CALIBRATION AND ADJUSTMENTS
To perform the following calibration and adjustment procedures, the cover must be
removed from the power supply. Because removal of the cover allows access to
potentially hazardous power voltages (up to 253 VAC or 450 VDC) and because of the
importance of accurate readings to performance, only technically trained personnel
should perform calibration procedures.
WARNING
Hazardous voltages exist on the rear of the
supply. Great care must be taken to avoid
both the input terminals, and while the
supply is enabled, the output terminals.
Only authorized personnel should perform
this procedure.
The calibration Test Setup procedures require the following: remove prime power, then
connect the power supply to a resistive load capable of full-rated voltage and current.
Connect a precision current shunt in series with either the positive or negative output
between the power supply and the resistive load. Two digital multimeters are required to
perform the calibration procedures.
To properly calibrate the power supply first calibrate the power converter then calibrate
the control card as described in the following sections.
