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 1 (+) and 2 (-), the multimeter (V1) for the reading in
DC supply 30 V range at terminals 1 (+) and 2 (-), the multimeter (DMM) for the reading in DC supply 20 mA range at terminals 14 (+) and 15 (-).
Execute the next test to verify D1020S unit channel or execute it twice to verified both D1020D unit channels.
Verify that green led on the front panel is ON.
Connect the unit as shown below:
If the power ON Led is 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”.
Set calibrator (CAL) at 20.000 mA and power supply (PS) at 20.0 V; verify that multimeter (V1) reads input voltage as 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.
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”.
