NI VirtualBench Calibration Procedure
5.
Call
PS Configure Current Output
with the following parameters:
•
Channel
=
ps/+6V
•
Current Level
=
0.01
or
0.03
, as listed in the first row of the
Verification Point
column of Table 22 or 23
•
Voltage Limit
=
6
, as listed in the first row of the
Voltage Limit
column of
6.
Wait for the DC power supply to settle. The VB-8012 requires at least 60 seconds of settling
time. The VB-8034/8054 requires at least 5 seconds of settling time.
7.
Measure the output voltage with the DMM and record the reading. Subtract the DMM
reading from the verification point. Verify that the calculation falls between the limits in
Table 22 or 23.
Note
Use the values in the
1 Year Limits
column. The values in the
24 Hour Limits
column are for a post-adjustment verification only.
