Performance Test Calibration 2
U2741A USB Modular 5.5 Digits Digital Multimeter Service Guide 19
DC current gain verification test
DC current configuration:
(CONFigure:CURRent[:DC] [<range|MIN|MAX|AUTO>
[,resolution|MIN|MAX|DEF>]])
1 Connect the calibrator to the front panel current HI and
LO input connectors.
2 Select each function and range based on the input current
in Table 2- 4.
3 Make a measurement and observe the result. Compare the
measurement results with the appropriate test limits
shown in Table 2- 4. (Be certain to allow for appropriate
source settling time when using the Fluke 5520A.)
