Note Before attempting to calibrate the power supply, you must unsecure the power supply,
and disconnect all loads from the power supply and connect a DVM across the output
terminals. See “Calibration Overview”, starting on page 62 to unsecure.

the calibration procedure as an example, so a different calibration value for
each calibration point may be prompted to be adjusted for your specific model.
1 Turn on the calibration mode.
Turn on the calibration mode by holding down (Calibrate) key as you
turn on the power supply and hold down the key until you hear a long beep.
Make sure that the power supply is in ‘‘CV’’ mode. If the power supply is not
in ‘‘CV’’ mode, an error occurs.
