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.
