7.
Adjust the external calibration constants using the DAQmx Adjust
SCXI Calibration VI.
8.
Repeat steps 5 through 7 for the seven voltage test points at the current
gain value in Table 3 or 4.
9.
Commit the calibration changes you made in the session using the
DAQmx Close External Calibration VI. The data is written to the
hardware in this step.
10. Repeat steps 3 through 9 for both gain values in Table 3.
11. Repeat steps 1 through 10 for the remaining channels.
You have finished adjusting the gain and offset of the SCXI-1102/B/C.
Verifying Adjusted Values
After calibrating the SCXI-1102/B/C, NI recommends that you verify the
analog input operation by repeating the steps listed in the
to ensure that the SCXI-1102/B/C is operating within its test
limits.
