Ma Measure; 712 Calibration (V1.2 Through V1.9) - Fluke 712 Calibration Manual

mA Measure

1. Disconnect all four test leads from the Fluke 5520A and the 712 Calibrator.
2. Connect the two test leads from the AUX jacks on the Fluke 5520A to the middle
jacks on the 712 Calibrator (black to black; red to red).
3. Press any key on the 712 Calibrator. The display will change to:
INPUT
4. Set the Fluke 5520A to 0.00000 mA and press O.
5. Press any key on the 712 Calibrator. The display should read:
INPUT ----- mA
then change to:
INPUT 0.00 mA
6. Again, press any key on the 712 Calibrator, still with a 0.00000 mA input from the
Fluke 5520A. The display should read:
INPUT ----- mA
then change to:
INPUT 2.000 mA
7. Set the Fluke 5520A to 2.00000 mA.
8. Press any key on the 712 Calibrator. The display should read:
INPUT ----- mA
then change to:
INPUT 0.500 mA
9. Set the Fluke 5520A to 0.50000 mA.
10. Press any key on the 712 Calibrator. The display should read:
INPUT ----- mA
11. Press any key on the 712 Calibrator and the unit will automatically reset itself, with
all segments momentarily being displayed. Calibrator is now out of CAL mode. Press

712 Calibration (V1.2 through V1.9)

1. Hold down R and C while turning the power on.
2. Hold the two keys until CAL is displayed, then release the two keys. The display
should read:
INPUT 15 Ω
3. Connect the two test leads from the NORMAL jacks of the 5520A to the INPUT
jacks (two middle jacks) on the 712 Calibrator (black to black, red to red).
4. Connect two additional test leads, also from the NORMAL jacks of the 5520A, to the
712 Calibrator (black wire to the 712 red jack labeled [3W NC] and red wire to the
red jack labeled [4W NC]). All four input jacks of the 712 should now be configured
in a 4-wire ohm measurement.
5. Set the Fluke 5520A to 15Ω and press O.
6. Press C. The display should read:
