20 Keysight M9182A/M9183A Calibration and Verification Procedure
Test 2: DC Current Verification Test
1 Make sure you have read “Test Considerations” on page 16.
2 Remove all connections from the DMM, select DCI function and perform a null
measurement. (The input terminals should be left open for the null
measurement).
3 Connect the calibrator to the Current input terminals of the DMM, as shown
below.
4 On the M9182A/83A DMM, select each function and range in the order shown
below. Using the calibrator, provide the input shown in the table below.
5 Make a DC current measurement on the M9182A/83A DMM and return the
result. Compare measurement results to the appropriate test limits shown in
the table. Be certain to allow for appropriate source settling when using the
Fluke 5720A.
