INPUT
3. Connect the test lead from the NORMAL jacks of the Fluke 5520A to the INPUT
jacks (two middle jacks) on the 712 Calibrator (black to black, red to red).
4. Set the Fluke 5520A to 0.0000 mV and press O. Press any key on the 712
Calibrator. The display should read:
INPUT
then change to:
INPUT
5. Press any key on the 712 Calibrator. The display should read:
INPUT ----- mV
then change to:
INPUT 160.00 mV
6. Set the Fluke 5520A to 160.0000 mV.
7. Press any key on the 712 Calibrator. The display should read:
INPUT ----- mV
then change to:
INPUT 320.00 mV
8. Set the Fluke 5520A to 320.0000 mV.
9. Press any key on the 712 Calibrator. The display should read:
INPUT
then change to:
INPUT
10. Set the Fluke 5520A to 640.000 mV.
11. Press any key on the 712 Calibrator. The display should read:
INPUT ----- mV
then change to:
INPUT 1280.00 mV
12. Set the Fluke 5520A to 1280.000 mV.
13. Press any key on the 712 Calibrator. The display should read:
INPUT ----- mV
then change to:
INPUT 400.00 R 4W
Resistance Measure
1. Connect two additional test leads 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 in a 4-wire
ohms measurement configuration.
2. Set the Fluke 5520A to 400.00 Ω and press O.
3. Press any key on the 712 Calibrator. The display should read:
INPUT ----- R 4W
then change to:
