OUTPUT VOLTAGE PARAMETER CALIBRATION
6.6.4
The following procedure calibrates parameters associated with the output voltage:
programming voltage (remote sense), readback voltage, overvoltage protection (OVP),
undervoltage protection (UVP), and readback of local voltage (internally sensed).
Voltage calibration is made with remote sensing, and with external sense leads
connected to the front panel output terminals. Voltage measurements with the external
voltmeter are made at the front panel output terminals, at the same points where the
sense leads are connected.
1. Connect a voltmeter across the output terminals. Ensure that no load is
2. Issue clear and reset commands:
3. Set the OVP supervisory to non-tracking and at maximum range:
4. Turn on the output:
5. Set the output current to full-scale:
6. Program the output voltage to the first value near 5% of full-scale,
7. Measure the output voltage with the external voltmeter. Enter this as value-1 with
8. Program the output voltage to the second value near 27.5% of full-scale,
