There is some interaction of the adjustments for offset and range of the output voltage
and current. Perform the offset adjustments before the range adjustments. It may take
several iterations to accurately make both adjustments.
There is some variation of the output current at high current levels because of the
temperature coefficient of the internal current shunts. Perform the current calibration
with the power supply initially at room temperature.
Refer to Figure 5-1 for the location of test points and potentiometers on the Main PWA,
and to Figure 5-2 for location of potentiometers on the Display PWA.
