- Supply the board with +9 V on +VCC and -9 V on -VCC
- Turn on the PWR switch
- Adjust the voltage with the COARSE trimmer
For each channel, the output voltage can be trimmed at ±50 mV. Adjustment can be done internally with the FINE trimmer or externally by applying a voltage between -5 V and +5 V on the TRIM input of the screw terminal. A jumper allows to choose between the two modes of operation (INT or EXT).
