Appendix C: Calibration and adjustment Series 2280 Precision DC Power Supply Reference Manual
C-8 077085503 / March 2019
Use the following steps to short the output terminals and sense terminals:
Insert the jumper wires in the output mating connector.
Connect the mating connector to the terminal on the back side of the Series 2280.
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.
