Calibration connection
You can calibrate the instrument using the front panel or by remote commands using ethernet, GPIB,
or USB interfaces. Refer to Remote communications interfaces (on page 2-44) for more information
on communicating with the instrument.
The calibration instructions for the Series 2280 include the following procedures:
Voltage calibration
Low-current calibration on the 10 mA and 100 mA ranges
High-current calibration on the 1 A and 10 A ranges
You can perform these calibration procedures individually, but for the instrument to be calibrated
properly, all the procedures must be performed. After each procedure, save the calibration result and
exit the calibration procedure.
Before calibration, make sure the correct connections are made between the instrument and the test
equipment.
