TIP
The calibrator has a built-in RJ sensor (INT RJ) that compensates
for the measured reference junction temperature. You can generate
thermoelectromotive force that is based on the measured temperature
from the calibrator's output terminal and roughly check the measurement
(reading) on the thermometer under verication.
Because the thermoelectromotive force generated using this method does
not match that generated using an external RJ sensor,* the accuracy of
this measurement is not guaranteed. For further details on how to use the
temperature sensor, see Section 7.3, “Selecting the INT RJ Function.”
* The terminal temperature of the thermometer under verication is
measured using an external RJ sensor, and this temperature is used
as the reference junction temperature.
