Repeat this step with
calibrationArea
set to 1, and again with
calibrationArea
set to 3.
You have now finished adjusting the excitation channels of the
SCXI-1122 module.
Verifying Adjusted Values
After you complete the adjustment procedure, it is important that you verify
the accuracy of the adjusted values by repeating the procedure in the
Verifying the Operation of the Module
section. Verifying the adjusted
values ensures the SCXI-1122 module is operating within its test limits
after adjustments.
Test Limits
Table 3 contains test limits for the SCXI-1122 module. If the module was
calibrated within the last year, the output from the module should fall
between the Upper Limit and Lower Limit values.
