General calibration/adjustment procedure
The calibration procedures from the front panel are described in this section. For
output voltage calibration, disconnect all loads from the power supply and
connect a DVM across the output terminals to be calibrated. For output current
calibration, disconnect all loads from the power supply, connect an appropriate
current monitoring resistor across the output terminals to be calibrated, and
connect a DVM across the terminals of the monitoring resistor.
The following table shows calibration parameters and points which should be
used to calibrate the output voltage and current for each of the three outputs.
