This topic contains information for calibrating the National Instruments 9205 and National Instruments 9206 using Calibration Executive.
Calibration Executive Procedure Features:
|Adjustment||Manual Mode||Selectable Test Points
Approximate Test Time: 5 minutes
|Test Equipment|||||Test Conditions|||||Device Setup|||||Test Limit Equations|
The following table lists the test equipment required for calibrating NI 9205/9206 modules.
|Calibrator||Fluke 5700A||If this instrument is unavailable, use a high-precision voltage source with an accuracy of at least 10 ppm.|
|Connection Accessory||NI 9940||Use with NI 9205/9206 modules with screw terminal.|
|NI 9933||Use with NI 9205/9206 modules with DSUB.|
The following setup and environmental conditions are required to ensure the NI 9205/9206 meets published specifications.
|Note If the NI 9205/9206 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 9205/9206 Calibration Procedure.
TestPoints = TestValue ± (TestValue * GainError + Range * OffsetError + NoiseUncertainty)
GainError = ResidualAIGainError + GainTempco * (TempChangeFromLastInternalCal) + ReferenceTempco * (TempChangeFromLastExternalCal)
OffsetError = ResidualAIOffsetError + OffsetTempco * (TempChangeFromLastInternalCal) + INL_Error
NoiseUncertainty = RandomNoise * 3 / for a coverage factor of 3 Σ and averaging 100 points
