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.
Table 3-3. Parameters for Calibration
Note You can terminate any CAL SETUP without changing its calibration constants by
turning off power.
