A hexadecimal number between 0 and FFFFh will be shown on the current
display. 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 value to 60.882 V.
d)
Turn the voltage coarse knob to finish the calibration.
While performing the full voltage calibration the current display will show
Adc.
After the full voltage calibration the message
Done
is shown on the
current display for 1 sec. Then the power supply returns to the Calibration
menu.
4. Zero current calibration
a)
Select “I 0” for zero current calibration and turn the voltage coarse knob.
When you initiate the zero current calibration, the CV LED lights up and the
power supply will display:
Voltage display: I 0
Current display: ConA
b)
Connect a digital ammeter (B&K Precision 5491B or similar instrument) to
the output terminals of the power supply to initiate the zero current
calibration procedure. If a digital ammeter is not connected within 30
seconds, the power supply will abandon the current calibration procedure
and return to the Calibration menu.
The CV LED indicator will go off and the CC LED indicator will light on. The
power supply will then display:
Voltage display: I 0
Current display: hex number
