(Trigger Thermocouple Measurement command) Triggers a thermocouple temperature
measurement and shows the value of the measurement. Also changes the operating mode
to thermocouple measurement if this is not already the operating mode. (This command is
equivalent to sending
TC_MEAS;*WAI;VAL?
)
Responses: <measurement value>,
CEL
(value is in Celsius)
<measurement value>,
FAR
(value is in Fahrenheit)
0.00E+00,OVER
(value is over or under capability)
0.00E+00,OPENTC
(open thermocouple)
0.00E+00,NONE
(wrong mode or no measurement)
Example:
*TRG
shows
+2.500E+01,CEL
Trigger a thermocouple measurement and return 25.00 Celsius when the thermocouple
temperature measurement is 25

(Temperature Sensor Type command) Sets the temperature sensor type to thermocouple
(TC) or Resistance Temperature Detector (RTD) for temperature measurements. The
Calibrator simulates the RTD temperature as a resistance output on the NORMAL
terminals, and simulates the thermocouple temperature as a dc voltage output on the TC
terminals. If the temperature sensor type is changed, the temperature output is reset to 0
degrees C. When set, the Calibrator keeps the temperature sensor type until power off or
reset.
Parameters:
TC
(Thermocouple)
RTD
(Resistance Temperature Detector)
Example:
TSENS_TYPE RTD
Set the temperature sensor type to an RTD.

(Temperature Sensor Type query) Shows the temperature sensor type thermocouple (TC)
or Resistance Temperature Detector (RTD) for temperature measurements.

(Self Test command) Start self-test and shows a
0
for pass or a
1
for fail. If faults are
found, they are shown on screen (terminal mode) or are logged into the fault queue where
they can be read by the ERR? query (computer mode).
Response:
0
(pass self test)
1
(fail self test)
Example:

Shows
0
when self test is successful.
