c) The power supply will enter in calibration mode and will display:
Voltage display: C A L
Current display: U 0
You can browse the calibration menu by turning the current coarse knob.
Using the voltage coarse knob you can select one of the following
calibration procedures:
U 0 Zero voltage calibration
U F Full voltage calibration
I 0 Low current calibration
I F Full current calibration
The voltage fine and current fine knobs are not used.
Important note!
In order to perform a correct calibration procedure, you must select the full voltage
calibration option just after the zero voltage calibration option, and the full current
calibration option just after the low current calibration option.
2. Zero voltage calibration
a) Turn the current coarse knob to select “U 0” for zero voltage calibration
and press the Output On-Off button. The power supply will display:
Voltage display: U 0
Current display: hex number
On the current display, a hexadecimal number between 0 and FFFFh is
displayed. During the zero voltage calibration, the CV LED is lit.
b) Connect a digital voltmeter to the output terminals of the power supply
(B&K Precision 5491B or similar instrument).
