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.
