2. Zero voltage calibration
a) Turn the current coarse knob to select “U 0” for zero voltage calibration
and turn the voltage coarse knob. 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).
c) Use the current coarse and fine knobs to adjust the value displayed by the
power supply until the voltmeter indicates the closest value to 0 V.
d) Turn the voltage coarse knob to finish the calibration.
While performing the zero voltage calibration, the current display will show
Adc. After the zero voltage calibration, the message Done is shown on the
current display for 1 sec. Then the power supply returns to the Calibration
menu.
3. Full voltage calibration
To finish the voltage calibration procedure, the full voltage calibration must be done
after the zero voltage calibration.
a) Select “U F” for full voltage calibration and turn the voltage coarse knob.
The power supply will display:
Voltage display: U F
Current display: hex number
