Testing The Milliamp (Ma) Function; Testing The Microamp (Μa) Function - Fluke 80 SERIES III Service Information

If you use a Fluke 5100 Series Calibrator, activate the 50 Ω divider
override.
3. Apply 3.000 V.
The Meter display should read 3.000 V dc +/- 0.061 V dc.

Testing the Milliamp (mA) Function

To verify the accuracy of AC and DC current measurement functions, do the following:
1. Connect the Calibrator to the
