Note
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
mA
µ
A and COM inputs on the Meter.
2. Turn the rotary switch to
mA/AC.
The Meter enters the DC measurement function
3. Apply the inputs in steps 1 and 2 in Table 11.
4. For each input, compare the readings on the Meter display to the display readings for
your Model of Meter.
5. Press the blue button on the Meter to toggle to AC measurement function.
6. Apply the inputs in steps 3 through 6 in Table 11.
7. For each input, compare the readings on the Meter display to the display readings for
your Model of Meter.

Testing the Microamp (µA) Function
To verify the accuracy of the microamp (µ
A
) measurement function, do the following:
1. Connect the Calibrator to the
mA µA and COM inputs on the Meter.
2. Turn the rotary switch to
µAC.
The Meter enters the DC measurement function.
3. Apply the inputs in steps 1 and 2 of Table 12.
4. For each input, compare the readings on the Meter display to the display readings for
your Model of Meter.
5. Press the blue button on the Meter to toggle to the AC measurement function.
6. Apply the inputs in steps 3 and 6 of Table 12.
