* The 3 A range full-scale test points are limited to 2 A in this table because of the accuracy
limitations of Fluke Models 57xxA and 5725A series calibrators at currents above 2.2 A.

AC current verification

The following topics describe how to verify AC current.
Verify AC current on the 100 µA to 3 A ranges
To verify AC current accuracy, you will:
•
Apply accurate voltages from the Fluke 5720A or 5730A multifunction calibrator to the DMM6500
front-panel terminals.
•
Verify that the displayed readings fall within specified limits.
