6. Press
C
to complete OHMS OUTPUT low range calibration. "CHEC" will be
displayed for 1 second. The new calibration constants are applied and the calibration
can be checked.
7. Press
C
to go to the next mode.
OHMS OUTPUT High Range
1. In OHMS OUTPUT high range mode, the unit will display " 20.0" and will source
OHMS using the default calibration. Keep the connections from the previous mode.
The DMM should read 20.0 Ohms +/- 5%.
2. Adjust the value for OHMS OUTPUT using the arrows on the 712 keypad to source
exactly 20.0 Ohms.
3. Press
C
to go to the next calibration point. "4000.0" will be displayed.
4. Adjust using the arrows on the keypad to source exactly 4000.0 Ohms.
5. Press
C
to complete OHMS OUTPUT high range calibration. "CHEC" will be
displayed for 1 second. The new calibration constants are applied and the calibration
can be checked.
6. Press

to complete calibration.
714 Calibration (Earlier than V2.0)
Temperature Measure
1. On the 714 Calibrator press and hold the
pressing and releasing the O key.
2. When the display momentarily shows CAL, release both the
puts the 714 into the Cal Mode. The 714 should display:
INPUT
3. Connect the two-wire copper test lead (banana jacks to mini-connector) from the
NORMAL jacks of the Fluke 5520A to the TC jack on the 714 Calibrator, observing
correct polarity.
4. Set the Fluke 5520A to 0.0000 mV and press O.
5. Press any key on the 714 Calibrator. The display should read:
INPUT -------- mV
then change to:
INPUT
6. Set the Fluke 5520A to 77.0000 mV.
7. Press any key on the 714 Calibrator. The display should read:
INPUT -------- mV
then change to:
OUTPUT
Temperature Source
1. Remove the copper test lead from the 714 Calibrator.
2. Press any key on the 714 Calibrator. The display should read:
