Front Panel Voltage and Current Calibration
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.
In the following procedure, the Agilent E3640A model is referenced to describe
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.
Voltage and OVP Calibration
2 Move down a level to the voltage calibration mode.
3 Select the low-end voltage calibration point.
4 Enter the reading you obtained from the DVM by using the knob and
resolution selection keys.
