Calibration Procedures 1
Keysight E3632A Service Guide 45
V LO 0.4500 V
7 Pressing the Calibrate key saves the change and selects the middle voltage
calibration point.
V MI 15.000 V
If the entered number is within an acceptable range, an ENTERED message
appears for one second. If the entered number is not correct, a MIN VALUE or
MAX VALUE message appears for one second and the display shows the low
voltage calibration point again. The display now shows the middle voltage
calibration point.
8 Read the DVM and change the middle voltage value on the display to match
the measured voltage.
For example, if the DVM reads 14.995 V, adjust the voltage to 14.995 V using
the knob and arrow keys.
V MI 14.995 V
9 Pressing the Calibrate key saves the change and selects the high voltage
calibration point.
V HI 29.500 V
If the entered number is within an acceptable range, a ENTERED message
appears for one second. If the entered number is not correct, a MIN VALUE or
MAX VALUE message appears for one second and the display shows the
middle voltage calibration point again. The display now shows the high
voltage calibration point.
10 Read the DVM and change the high voltage value on the display to match the
measured voltage.
For example, if the DVM reads 28.995 V, adjust the voltage to 28.995 V using
the knob and arrow keys.
V HI 28.995 V
11 Pressing the Calibrate key saves the new voltage calibration constants, and
goes to the OVP calibration mode.
CAL SETUP 2
A CALIBRATING message appears for one second to indicate that the voltage
calibration is progressing and new voltage calibration constants of “SETUP 1”
are stored. Then, the display shows above message to indicate that the power
supply is ready for the OVP calibration.
