General Calibration/Adjustment Procedure

General Calibration/Adjustment Procedure
N o t e The power supply should be calibrated after 1-hour warm-up with no load connected.
And Perform the voltage calibration prior to the OVP calibration.
The front panel calibration procedures 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, also disconnect all loads from the power supply, connect
an appropriate current monitoring resistor 0.01
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.
The following table shows calibration parameters and points which should be used to
calibrate the output voltage and current.
