Zero verify the DMM6500:
1. On the calibrator, select the OPR/STBY key. Make sure that the front panel displays STANDBY.
2. Set the ranges to 100 mA.
3. Verify the DMM6500 zero reading for each range.
4. Source dc current from the following table. For each setting, be sure that the reading is within
stated limits.
5. Repeat these steps for the 1 A and 3 A ranges.

* 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.
Verify dc current 10 A range
See DC current 10 A range verification (on page 2-47) under Rear-panel verification (on page 2-46).
