3.4.8 Specifying the Thermocouple Cold Junction
The
Internal/External Cold Junction function in the Setup menu makes it possible
to specify whether the
internally measured temperature inside the calibrator or the
externally
measured temperature will be used as the cold junction for thermocouple
simulation with the calibrator.
If
external cold junction temperature is selected, a dialog box appears which can be
used to manually enter the measured cold junction temperature (the temperature at
the connection for the simulated thermocouple sensor). If the METRAHit multimeter
with temperature sensor c
onnected to the PC is used for this temperature
measurement, the temperature can be read in online by clicking the
“Get from
multimeter
” button. If the “Link Calibrator with Multimeter” checkbox has been
activated, the temperature is continuously monitored
by the multimeter, forwarded to
the calibrator via the port and taken into account by the calibrator.
