Calibrating for Programming Accuracy
The factory calibrates the offset and range of the voltage and current programming
circuits to within 1% for the default 0-5 Vdc programming signals. You may need to
recalibrate when you change SW1 switch settings to use 0-10 Vdc programming or
when you switch back to 0-5 Vdc programming after previously calibrating for
0-10 Vdc programming.
Make calibration adjustments using multi-turn potentiometers, accessed through
holes in the cover of the power supply. See
Figure 5.2 for the location of each of the
pots.

WARNING
Use a non-conducting, straight-bladed screwdriver to adjust the trim pots.
