Calibration Procedures 1
Keysight E3632A Service Guide 43
General Calibration/Adjustment Procedure
The calibration procedures from the front panel are described in this section. For
voltage calibration, disconnect all loads from the power supply and connect a
DVM across the output terminals. For current calibration, disconnect all loads
from the power supply, connect an appropriate current monitoring resistor
(0.01 Ω) across the output terminals, and connect a DVM across the terminals of
the monitoring resistor.
The following table shows calibration parameters and points which should be
used to calibrate the output voltage and current.
Table 1-4 Parameters for calibration
The power supply should be calibrated after 1-hour warm-up with no load
connected.

V HI
CAL SETUP 2 OVP None
CAL SETUP 3 Current

CAL SETUP 4 OCP None
– 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.
