General Calibration or Adjustment Procedure

The front panel calibration procedures are described in this

section.

• For voltage calibration, disconnect all loads from the

power supply and connect a digital voltmeter (DVM)

across the output terminals.

• For current calibration, also 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.

• You can abort a calibration at any time by turning the

power supply off from the front panel, by issuing a

remote interface device clear message, or by pressing the

front panel Local key.

Table 8- 8 shows the calibration parameters and points

which should be used to calibrate the output voltage and

current.

NOTE

The power supply should be calibrated after a 1-hour warm-up with no

load connected. Perform the voltage calibration prior to the OVP

calibration.
