TC_REF?
(Thermocouple Reference query) Return the source and value of the temperature being
used as a reference for thermocouple simulation and measurement (in Celsius, CEL, or
Fahrenheit, FAR, depending on active units). The choices are Internal reference (INT) or
External reference (EXT).
If INT is returned, the reference temperature return is 0 unless you are in a thermocouple
mode of operation and the 5500A Calibrator is in Operate.
Responses:
Example:
Return Internal, 29.88, Celsius, when the thermocouple reference is internal and at
29.88 C. (If the temperature return for the internal reference is 0 (0.00E+00), the
5500A Calibrator is not in Operate, and/or the Calibrator is not in a thermocouple mode.)
TC_TYPE
(Thermocouple Type command) Set the Thermocouple (TC) temperature sensor type.
The TC type is used when the output is set to a temperature value with the OUT
command and the temperature sensor type is set to TC with the TSENS_TYPE
command. When the thermocouple type is changed while simulating a temperature
output, the temperature is changed to 0 C. Once set, the 5500A Calibrator retains the
TC type until power off or reset.
Parameters: B
Example:
Set the thermocouple type for simulating a temperature output to a J-type thermocouple.
