Chapter 3 Calibration Procedures

General Calibration/Adjustment Procedure

The calibration procedures from the front panel are desc ribed in this section.

For voltage calibration,

disconnect

all loads from the power su pply and

connect a DVM across the output terminals. For current calibration,

disconnect all loads from the power supply, connect an appropriate current

monitor ing resi stor 0.01

across the output terminals, and connect a DVM

across the terminals of the monitoring resistor.

Note that the power supply should be calibrated

after 1-hour warm-up

with

no load conne cted .

The following table shows calibration parameters and points which should be

used to calibrate the output voltage and current.

Table 3-2. Parameters for Calibration

Note You can terminate any CAL SETUP without changing its calibration constants by

turning off power.

Note Perform the voltage calibration prior to the OVP calibration and the current

calibration prior to the OCP calibration.
