Front panel voltage and current calibration
In the following procedure, the E3646A 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 the (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 the CV mode. If the power supply is not
in the 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.
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. Refer to “Calibration” on page 85 to unsecure.
