Add a temperature offset of +10
°
C to the thermocouple measurements.
TC_OFFSET?
Sequential Overlapped Coupled IEEE-488 RS-232
x x x x x
(Thermocouple Temperature Measurement Offset query) Returns the temperature offset
used for thermocouple measurements (±500
°
C).
Responses: <value>
CEL
(offset in Celsius) (optional)
<value>
FAR
(offset in Fahrenheit) (optional)
Example:
TC_OFFSET?
returns
1.000E+01,CEL
Returns 10 Celsius when a temperature offset of +10
°
C has been added to the
thermocouple measurements.
TC_OTCD
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(Thermocouple Open Detection command) Activates or deactivates the open
thermocouple detection circuit in thermocouple measurement mode. Once set, the
Calibrator retains open thermocouple detection circuit setting until power off or reset.
Parameters:
ON
(turn on thermocouple detection circuit) (default)
OFF
(turn off thermocouple detection circuit)
Example:
TC_OTCD ON
Activate the open thermocouple detection circuit. If an open thermocouple is detected,
this condition is displayed on the front panel.
TC_OTCD?
Sequential Overlapped Coupled IEEE-488 RS-232
x x x x x
(Thermocouple Open Detection query) Returns the status of the open thermocouple
detection circuit in thermocouple measurement mode.
Responses:
ON
(thermocouple detection circuit is on)
OFF
(thermocouple detection circuit is off)
Example:
TC_OTCD?
returns
ON
Returns
ON
when the open thermocouple detection circuit is activated.
TC_REF
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(Thermocouple Reference command) Sets whether the internal temperature sensor (INT)
or an external reference value (EXT) is used for Thermocouple (TC) outputs and
measurements. If the first parameter is EXT, the second parameter must be the
temperature value to use as the reference for the thermocouple reference junction
temperature. Once set, the Calibrator retains reference setting until power off or reset.
Parameters:
INT
EXT
, <value of external reference>
CEL
(or
FAR
)
Example:
TC_REF EXT, 25.6 CEL
Set the thermocouple reference to external, with a value of 25.6
°
C.
TC_REF?
Sequential Overlapped
Coupled
IEEE-488 RS-232
x x x x x
(Thermocouple Reference query) Returns 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).
