This topic contains information for calibrating the National Instruments SCXI-1102/B/C using Calibration Executive.
Calibration Executive Procedure Features:

|Note The SCXI-1102/B/C calibration procedure does not support multiplexed mode.|
The following table lists the test equipment required to calibrate SCXI-1102/B/C modules.
|Calibrator||Fluke 5700A||If this instrument is unavailable, use a high-precision voltage source that is accurate to at least 50 ppm.|
|If one of these instruments is unavailable, use a multiranging 6 1/2 digit DMM.|
|NI E/M Series DAQ Device||NI 6030E,|
|SCXI Adapter||SCXI-1349||Adapter to connect SCXI systems to plug-in data acquisition devices.|
|Shielded DAQ Cable||NI Sh68-68-EP||Use with E/M Series DAQ devices.|
|Ribbon Cable||—||Use a 50-pin ribbon cable.|
|Connector Block||NI CB-50||—|
|Note The Calibration Executive procedure runs in automated mode if you use IVI-supported instruments.|
The following setup and environmental conditions are required to ensure the SCXI-1102/B/C meets published specifications.
|Note The SCXI-1102/C calibration procedure may return an IVI interface error, (-1074135039). This error occurs if you have reconfigured the SCXI module to measure current rather than voltage by installing current shunt resistors. Calibration Executive can only calibrate this module when it is configured to measure voltage.|
|Caution The SCXI module must be cabled to the E/M Series DAQ device as described in this step. Otherwise, the calibration may fail.|
The calibration procedure guides you through the connections between your calibrator, DMM, and the SCXI module. The initial connections are as follows:
If the SCXI-1102/B/C module is not recognized in MAX, make sure that you followed the configuration guidelines. If MAX fails to recognize the SCXI-1102/B/C module after you reconfigure and refresh (<F5>), contact NI technical support.
The SCXI chassis power supply may be injecting noise into your measurement if the SCXI-1102/B/C is installed in Slot 1 or 2 of the chassis.
If the SCXI-1102/B/C module fails after calibration, check the connections and run the Calibration Executive procedure again.
The following test limits are derived from published specifications
TestLimits = TestValue ± [abs(TestValue) * % of reading + Offset + average system noise]
