712 Calibration (V1.2 Through V1.9) - Fluke 71X Series Calibration Manual

712 Calibration (V1.2 through V1.9)

1. Hold down  and  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 push .
6. Push . The display should read:
INPUT ----- Ω,
then change to:
INPUT 350 Ω
7. Set the Fluke 5520A to 350 Ω.
8. Push . The display should read:
INPUT ----- Ω
then change to:
INPUT 500 Ω.
9. Set the Fluke 5520A to 500 Ω.
10. Push . The display should read:
INPUT ----- Ω
then change to:
INPUT 3200 Ω
11. Set the Fluke 5520A to 3200 Ω.
12. Push . The display should read:
INPUT ----- Ω.
then change to:
OUTPUT 17-50 Ω.
13. Using four test leads, connect the four jacks of Fluke 8508A (Ω Sense 'Hi & Lo' and
Input 'Hi & Lo') to the two middle jacks of the 712 Calibrator (black to black; red to
red). This puts the Fluke 8508A in a 4-wire configuration.
14. Set the 3458A to the 1000 Ω range.
15. Push  and  until the 712 display matches the Fluke 8508A.
16. Push . The display should read:
OUTPUT ----- Ω
then change to:
OUTPUT 350.00 0.
17. Push  and  until the 712 display matches the Fluke 8508A.
