The following table lists the test equipment required for calibrating NI 9211 modules.
|Calibrator||Fluke 5520A using the 3.3 V range*||A high-precision voltage source with ≤7 µV of uncertainty at 75 mV and ≤2 µV of uncertainty at 0 V and an output impedance of <5 Ω.|
|Connection Accessory||NI 9932||—|
|* Because the 3.3 V range has a low output impedance.|
The following setup and environmental conditions are required to ensure the NI 9211 meets published specifications.
|Note If the NI 9211 module fails after calibration, return it to NI for repair or replacement.|
The following test limits are derived from the published specifications found in the NI 9211 Calibration Procedure.
TestLimits = TestValue ± (TestValue * % of Reading + Offset Error)
