Set multimeter (DMM) for the reading in DC supply, 10 V range.
Set calibrator (CAL) at 20.000 mA and power supply (PS) at 9.0 V; verify that output voltage (20 mA current on the 250
Ω
shunt resistance) read by multimeter (DMM) is
5.000 V ± 10 mV.
Check that dip switch in the unit is in 1-5 V mode (see “Configuration” section for dip switch position). Connect the unit as shown below:

For voltage output please follow step 2
Calibration instruction and Troubleshooting
In case a calibration check or readjustment is necessary the following equipment is required:
Set power supply (PS) at 24.0 V at terminals 3 (+) and 4 (-), the calibrator (CAL) in the function “mA” 20 mA range at terminals 14 (-) and 15 (+), the multimeter (V1) for the reading in
DC supply 30 V range at terminals 14 (+) and 15 (-), the multimeter (DMM) for the reading in DC supply 20 mA range at terminals 1 (+) and 2 (-).
Execute the next test to verify D1014S unit channel or execute it twice to verified both D1014D unit channels.
Check that dip switch in the unit is in 4-20 mA Source Mode (see “Configuration” section for dip switch position). Connect the unit as shown below:
If the power ON Leds are off, check supply voltage, polarity and wiring.
Set calibrator (CAL) at 4.000 mA and verify that the output current, read by multimeter (DMM), is correspondent with a maximum deviation presented in the section “Technical Data”.
Set calibrator (CAL) at 20.000 mA and verify that the output current, read by multimeter (DMM), is correspondent with a maximum deviation presented in the section “Technical Data”.

If the maximum deviation is exceeded, repeat the board calibration and proceed in the following way:
Set the calibrator (CAL) at 20.000 mA and regulate the current, read by multimeter (DMM), by turning the span trimmer of the unit (see “Configuration” section) until reading
20.000 mA ± 5 µA value.
Set the calibrator (CAL) at 4.000 mA and regulate the current, read by multimeter (DMM), by turning the zero trimmer of the unit (see “Configuration” section) until reading
4.000 mA ± 5 µA value.
Repeat the last two steps to verify that the span trimmer’ s movement has not significantly modified the value of zero (a dragging of 1/5 exists when moving span and zero values.
To execute a linearity test: set the calibrator (CAL) at 4.000, 8.000, 12.000, 16.000, 20.000 mA and verify current output is correspondent with a maximum deviation presented in
the section “Technical Data”.
Set calibrator (CAL) at 20.000 mA and verify that the transmitter voltage, simulated by calibrator (CAL) and read by multimeter (V1), is correspondent at 15.30 V ± 0.1 V.
If the transmitter voltage is not correct, regulate it by turning the Vtx trimmer of the unit (see “Configuration” section) until reading the correct value.
