STEP 2

Set the PCB jumpers

Set the Normal/Reverse jumper to the NORM position. If a reverse acting signal is required, it will be set 

later in the procedure.

Set the OFFSET jumper to the 0 position. If an offset is required, it will be set later in the procedure.

Set the IN jumper to the V position. If a current input signal is required, it will be set later in the procedure.

Set the OUT jumper to the V position. If a current output signal is required, it will be set later in the procedure.

STEP 3

Make the wiring connections

Ensure the power supply is turned off when making connections.

Connect 24 Vdc to the PWR terminal.

Connect the power supply common, the voltmeter common (-) and the input signal common to the COM 

terminal.

Connect the + of the input voltage signal to the IN terminal.

Connect the + of the voltmeter to the OUT terminal.

STEP 4

Apply power

Turn on the 24 Vdc power supply and the POWER LED should light.

STEP 5

Input/Output signal calculation

Calculate the required INPUT voltage signal span.

Vin_span = Vin_max - Vin_min

Examples, 0-5 V input = 5 volt span, 3-12 V = 9 volt span

If the input is to be 4-20 mA, use the equivalent calibration voltage calculated previously, 4-20 mA = 1 - 5 

V = 4 V span.

Calculate the required OUTPUT voltage signal span.

Vout span = Vout max - Vout min

Examine, 3-15 V output = 12 volt span

STEP 6

Apply the input voltage span result to the IN terminal. For example, if the calculated input span is 9 volts, 

apply 9 volts to the IN terminal.

Compare the output meter reading to the output voltage span number calculated previously. If the meter 

reads higher, then adjust the ATTN pot until the meter equals the output span value. If the meter equals 

the output span value.

During this adjustment, the input signal should be as stable as possible and the output adjustment should 

be as precise as possible to obtain the best results.

STEP 7

Offset adjustment

The offset adjustment shifts the output signal up or down. For example, a 1-5 volt output signal has a 1 

volt of offset.
