mV OUTPUT

1. In mV OUTPUT mode, the unit will display "C -10" for 1 second followed by " –
10.000". The calibrator is now sourcing mV using the default calibration. The 714
should source approximately –10.000mV through copper wire.
2. Adjust the source value using the up and down big arrows for gross and small arrows
for fine, until you read -10.000mV.
3. Press
C
key to go to the next calibration point. "C 75" will be displayed for 1
second and then " 75.000". The 714 should source approximately 75.000mV.
4. Adjust the source value until you read 75.000 mV on the DMM.
5. Press
C
to complete mV OUTPUT calibration.

mV INPUT

1. In mV INPUT mode, the unit will display "C -10" for 1 second and then will display
the input voltage using the default calibration.
2. Source -10.000 mV from the 5520. The unit should read approximately –10.000 mV
through copper wire.
3. Press
C
to go to the next calibration point. "C 75" will be displayed for 1 second
and then the input voltage.
4. Source 75.000 mV from the 5520. The unit should read approximately 75.000mV .
5. Press
C
to complete mV INPUT calibration. "CHEC" will be displayed for 1
second. The new calibration constants are applied and the mV INPUT calibration can
be checked.
6. Press
C
to go to the next mode.

CJC

1. In CJC Cal Mode the unit will display "C CJC" for 1 second followed by IN 0°C for
another second. Next it will display the difference between the temperature as
measured by the CJC sensor and the temperature measured by a J type thermocouple.
2. Use the 5520 with J Type thermocouple wire to input a J type thermocouple signal of
0°C with CJC on.
3. When the number displayed on the 714 is stable, press the
calibration.
