Front Panel Calibration
Front panel calibration includes voltmeter, ammeter, voltage and current preview
and over voltage protection (OVP) setpoint and preview functions. Perform all
procedures in the sequence give.
Additional
Setup
Make calibration adjustments using multiturn potentiometers accessed by removing
the power supply’s cover.
1. Unfasten the cover and move it back one inch from the front to allow access to
the calibration potentiometers on the A1 PCB. Refer to
for the
location of the pots.
2. Perform the following calibration procedures.

Calibration
1. Connect the DVM to the output bus bars at a point close to the chassis. Turn the
current control knob fully clockwise.
2. Increase the output voltage to show the maximum rated voltage on the external
DVM. Adjust the voltmeter full scale adjust potentiometer (R50) until the front
panel voltmeter reads the maximum rated output voltage. Check that the front
panel voltage mode LED turns on.
