VREF100 mechanical interface

Quick start

  1. Supply the board with +9 V on +VCC and -9 V on -VCC
  2. Turn on the PWR switch
  3. Adjust the voltage with the COARSE trimmer

Fine adjustment

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).
