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.
Due to the importance of accurate readings to performance, only technically
trained personnel should perform calibration procedures.
The calibration and adjustment procedures require two digital multimeters. To
set up for the calibration procedures, first perform the following:
1. Remove prime AC power.
2. Connect the power supply to a precision current shunt (as shown in
Figure 4-1 below) capable of a minimum of 10% above full rated
output. A fan may be required to cool the shunt.
