Front Panel Voltage and Current Calibration
N o t e
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 67 to unsecure.
In the following procedure, the Agilent E3646A 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.
