12. Set the calibrator voltage to the Test Point value in Table 3 that
corresponds to the gain from step 10.
13. Call
DAQ_Op
to retrieve measurement data from the SCXI-1122
module.
Set the following parameters:
•
deviceNumber
—The value assigned by MAX
•
chan
—0
•
gain
—1
•
count
—100
•
sampleRate
—100
The data is returned to the buffer variable.
14. Call
SCXI_Scale
to convert the acquired readings into scaled voltage
values. Set the following parameters:
•
SCXIChassisID
—The value assigned by MAX
•
moduleSlot
—0
•
channel
—0
•
SCXIgain
—The gain from step 10
•
TBgain
—1
•
DAQBoard
—The value assigned by MAX
