)
4. Verify that the power supply readout displays cL00, indicating calibration
mode.
5. Configure the DMM to measure 2 amperes DC.
6. Enter 4 on the power supply keypad and press (
).Verify that the “PARA”
indicator lights up on the display and the readout displays cL40, indicating
parallel output current offset calibration.
7. Enter the DMM reading on the power supply keypad and press (
). The
power supply readout will return to normal in approximately 10 seconds.
The calibration is complete.
