5.4 Unipolar Output Calibration
If you choose Unipolar mode for analog output, you have to go through the
Unipolar Output Calibration. There are two steps: Gain Calibration and Offset
Calibration.
Gain Calibration:
1.
Set jumpers JP1 and JP5 (for CH1) or JP2 and JP9 (for CH2) to
unipolar,
and choose an internal reference as
-5V
.
2.
Set the digital data as (0000 0000 0000)
B
, trim VR4 (for CH1) or VR10
(for CH2) until the voltmeter reading is
0V
.
Offset Calibration:
1.
Set jumpers JP1 and JP5 (for CH1) or JP2 and JP9 (for CH2) to
unipolar
, and choose an internal reference as
-5V
.
2.
Set the digital data as (1111 1111 1111)
B
, trim VR3 (for CH1) or VR9
(for CH2) until the voltmeter reading is
5V
.
