1. On the 714 Calibrator push and hold the
pressing and releasing the  key.
2. When the display momentarily shows CAL, release both the
puts the 714 into the Cal Mode. The 714 should display:
INPUT 0.00 mV
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.
Copper wire must be used during this step.
4. Set the Fluke 5520A to 0.0000 mV and push
5. Push any key on the 714 Calibrator. The display should read:
INPUT -------- mV
then change to:
INPUT 77.00 mV
6. Set the Fluke 5520A to 77.0000 mV.
7. Push any key on the 714 Calibrator. The display should read:
INPUT -------- mV
then change to:
OUTPUT mV
1. Remove the copper test lead from the 714 Calibrator.
2. Push any key on the 714 Calibrator. The display should read:
OUTPUT ------ mV
After a few seconds, the display should change to:
0.0 °C
TYPE J
1. Connect the Type-J thermocouple test lead from the TC jack on the Fluke 5520A to
the TC jack on the 714 Calibrator, observing correct polarity.
Type-J thermocouple wire (not copper) must be used.
2. Set the Fluke 5520A to source Type-J thermocouple at 0.0 °C. Push
3. Push any key on the 714 Calibrator. The display will very quickly flash:
TYPE J ------ °C
then read:
TYPE J HOLD °C
4. Wait for three to five minutes. The longer the waiting period, the more accurate the
Thermo-block calibration will be.
5. Push any key on the 714 Calibrator. The display should read:
