General Calibration/Adjustment Procedure
30 E3632A Service Guide
To calibrate the output voltages and currents of the power
supply from the front panel, proceed as follows:
1 Unsecure the power supply.
To calibrate the voltage and current, you must unsecure
the power supply according to the procedure given on
page 59.
2 Disconnect all loads from the power supply and connect a
DVM across output terminals.
3 Turn on the calibration mode.
CAL MODE
Turn on the calibration mode by pressing the Calibrate key
while simultaneously turning on the power supply, and
then continue to hold the Calibrate key for about 5
seconds until a beep is heard. 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
4 Move down a level to the voltage calibration mode.
CAL SETUP 1
The display shows the above message to indicate that the
power supply is ready for the voltage calibration.
NOTE
• You can terminate any CAL SETUP without changing its calibration
constants by turning off power.
• Perform the voltage calibration prior to the OVP calibration and the
current calibration prior to the OCP calibration.
