Apply the minimum input voltage signal and note the output signal on the meter. If the output reading is 

correct, leave the OFFSET jumper in the 0 position and continue to the next step.

If the output reading must be increased to the desired value, then move the OFFSET jumper to the + 

position and adjust the OFF pot to obtain the correct minimum output on the meter.

If the output reading must be decreased to the desired value, then move the OFFSET jumper to the - 

position and adjust the OFF pot to obtain the correct minimum output on the meter.

Remember that increasing or decreasing the offset value will also increase or decrease the maximum 

output by the same amount.

STEP 8

Reverse action adjustment

If a reverse acting output signal is required (5-1 V for example), then move the REV/NORM jumper to the 

REV position. If this is not required then proceed to the next step.

Apply the minimum voltage input signal and adjust the REV pot for the maximum required output signal.

STEP 9

Make final jumper settings

If jumper settings are to be changed, first disconnect the power and input/output connections.

If a current input signal is required, then move the IN jumper to the mA position.

If a current output signal is required, then move the OUT jumper to the mA position.

Check the operation of the device with the correct signal types for proper signal rescaling and operation.
