Front Panel Operation
How to Connect the Calibrator to a UUT
4
4-11
When calibrating thermocouples, it is especially important to use the correct hookup wire
and miniconnector between the Calibrator front panel TC terminal and the UUT. You
must use thermocouple wire and miniconnectors that match the type of thermocouple.
For example, if simulating a temperature output for a type K thermocouple, use type K
thermocouple wire and type K miniplugs for the hookup.
To connect the calibrator to a UUT, proceed as follows:
1.
If the calibrator is turned on, press
R
to remove the output from the calibrator
terminals.
2. Make the connections to the UUT by selecting the appropriate figure from Table 4-1.
For capacitance outputs, null out stray capacitance by connecting the test leads to the
UUT, routing them (but not connecting) to the Calibrator on a non-conductive surface.
Null out the reading on the UUT using “rel,” “offset,” or “null,” whichever method
applies, and then connect the test leads to the Calibrator.
