NI 4071 7½-Digit FlexDMM Calibration Procedure

DC Current

Note

The 90-day DC current uncertainty of the Fluke 5720A is not adequate to 

calibrate the 100 µA and 1 mA DC current ranges listed in Table 25. You must 
characterize the calibrator output to better than published specifications. Use 
metrology laboratory methods to obtain the required uncertainty. Monitor the current 
applied using a DC current shunt/voltmeter system in series with the calibrator 
output. Refer to Table 13 for the recommended DC current uncertainty requirements 
for the DC current shunt/voltmeter system.

Note

Tolerances are relative to the nominal calibrator amplitude unless otherwise 

noted.
