TC_REF
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(Thermocouple Reference command) Sets if 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. When set, the Calibrator keeps 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?

x
(Thermocouple Reference query) Shows 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 options are Internal reference (INT) or
External reference (EXT).
If INT is shown, the reference temperature return is 0 unless you are in a thermocouple
mode of operation and the Calibrator is in Operate.
Responses:
INT

CEL
(or

)

(or

Example:
TC_REF?
shows
INT,2.988E+01,CEL
Shows 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
Calibrator is not in Operate, and/or the Calibrator is not in a thermocouple mode.)
TC_TYPE
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(Thermocouple Type command) Sets 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 you simulate a temperature output, the temperature
is changed to 0
°
C. When set, the Calibrator keeps the TC type until power off or reset.
Parameters:
B
(B-type thermocouple)
C
(C-type thermocouple)
E
(E-type thermocouple)
J
(J-type thermocouple)
K
(K-type thermocouple) (default)
N
(N-type thermocouple)
R
(R-type thermocouple)
S
(S-type thermocouple)
T
(T-type thermocouple)

Example:
TC_TYPE J
Set the thermocouple type to simulate a temperature output to a J-type thermocouple.
