WARNING
Exercise caution when resetting internal jumpers. Review
follow procedures for removing the cover and resetting jumpers in
Programming Output Voltage with a 0-1 mA Source
1. Remove the jumper between pins 20 and 21 of connector J3.
2. Connect the external programming source between pin 9 (voltage programming
input/positive) and pin 12 (return) of connector J3.
Varying the current source from 0 to 1 mA will vary the output voltage from 0 to 100% of the
model rating. Adjusting the front panel current limit control sets the output current limit.
Figure 4-6 Programming Output Voltage with a 0-1 mA Source
Programming Output Voltage with a 0-5k Resistance
1. Remove the jumpers connecting pins 8 to 9 and pins 20 to 21 on connector J3.
2. Connect pins 9 (voltage programming input/positive) and 21 (1 mA current source for
voltage control) to the counter-clockwise end of the 5k potentiometer and connect the
tap and clockwise end of the potentiometer to pin 12 (return).
Adjusting the resistance from 0 to 5k will vary the output voltage from 0 to 100% of the model
rating. The output current limit is set locally by adjusting the front panel current limit control.
