This topic contains information for characterizing DC current output for the National Instruments PXI-4071 at ±100µA and ±1mA. This process uses the Agilent 3458A in series with the PXI-4071 device to determine the value of the calibrator current output at ±100µA and ±1mA during the DC current verification test in Calibration Executive.

The following table lists the test equipment required for this procedure.
|Calibrator||Fluke 5720A/5730A||Used as current source only.|
|DMM||Agilent 3458A||See specification in the NI 4071 Calibration Procedure.|
|Low Thermal Test Leads (x3)||Fluke 5440A-7002||—|
The following setup and environmental conditions are required.
The F0 key now shows the Current Temp on the Agilent 3458A in Celsius.
The F1 key now shows the Last Adjustment Temp on the Agilent 3458A in Celsius.
|Note If Auto Cal has not been performed in the last 24 hours, or if the ACAL is >1° from the Current Temp, press [Auto Cal], and ensure that all cables are removed from the Agilent 3458A DMM.|
This ensures the DMM does not OVERRANGE when Calibration Executive changes the calibrator output after taking the measurement.
To perform a DC current characterization for an adjustment, repeat steps 5—20 of the Verification Procedure.
To perform a DC current characterization for re-verification, repeat steps 5—20 of the Verification Procedure.
