NI WSN-3226 Calibration Procedure
4.
Configure the NI WSN-3226 according to Table 2.
5.
Click
OK
.
6.
Right-click the NI WSN-3226 in the Project Explorer and select
Deploy
.
7.
Set the calibrator to a Test Point value indicated in Table 3.
8.
Create a VI in LabVIEW to acquire a voltage reading from the AI 0 variable on the
NI WSN-3226.
9.
Acquire and average 25 voltage readings with the NI WSN-3226.
10. Compare the average of the NI WSN-3226 readings with the 3-Year Limits in Table 3.
11. Repeat steps 7 through 10 for all test points in Table 3.
Note
The limits in Table 3 are derived using the values in Table 6.
If the Voltage Accuracy verification procedure determines that the NI WSN-3226 is outside of
the limits, refer to
for assistance in returning the device to NI.
