Display Verification
1. Press and hold the I key and then press and release the green O key. This locks
the 713 in a mode where all display segments are on. All segments will stay on until
the I key is released.
2. Check to see that all segments of the display are showing.
3. Turn the 713 off.
The 713 verification test is now complete.
714 Verification (Earlier than V2.0)
Thermocouple Measure Verification
1. Press the
O key to turn on the 714 Calibrator. Press the I key and the C key so
that the display indicates:
INPUT xx.x °C
where xx.x is some variable number; or OL (overload) may be indicated.
2. Press the
T key to measure Type J thermocouple and connect the Type J
thermocouple test lead from the TC jack of the Fluke 5520A to the TC jack on the
714 Calibrator, observing correct polarity.
3. Set the Fluke 5520A to output in Type J thermocouple, press the Okey, and set
the 5520A to the settings in Table 45, verifying the display readings on the 714:
Table 45. 714 Thermocouple Measure Verification
Fluke 5520A Fluke 714
-200.00 °C -200.9 °C to -199.1 °C
0.00 °C -0.7 °C to +0.7 °C
1200.00 °C 1199.3 °C to 1200.7 °C
4. Disconnect the Type J thermocouple test lead and install the two-wire copper test
lead from the Fluke 5520A NORMAL jacks to the 714 Calibrator TC jack, observing
correct polarity.
5. On the 714 press the
T key until "mV" is shown on the display.
6. Set the Fluke 5520A to the settings in Table 46, and verify the display readings on
the 714 Calibrator.
Table 46. 714 Thermocouple Measure Verification (mA)
Fluke 5520A Fluke 714
-10.0000 mV -10.03 to -9.97 mV
30.0000 mV 29.97 to 30.03 mV
75.0000 mV 74.97 to 75.03 mV
7. Disconnect the copper test lead from the Fluke 5520A.
