Use the following steps to short the output terminals and sense terminals:
Step
Description
1
Insert the jumper wires in the output mating connector.
2
Connect the mating connector to the terminal on the back side of the 2281S.
3
Slide the cable housing over the output mating connector and wires.
Current calibration connections
For current calibration, the following equipment is required:
Digital multimeter
Precision shunt resistors
Electronic load or resistor
You can use either an electronic load or a resistor to perform current calibration.
When calibrating the 1 A and 10 A ranges (step 5 to step 8), we recommend that you use an
electronic load for lowest thermal drift and current stability. When calibrating the 10 mA and 100 mA
ranges (step 3 and step 4), we recommend that you use a resistive load for lowest noise and
repeatability.
You are required to change the shunt and load configuration for certain steps. Refer to the figures for
proper setup.
