:TCOefficient <n>
[:SENSe[1]]:TEMPerature:RJUNctionX:REAL:TCOefficient <n> Specify temperature coefficient
Parameters <n> = -0.09999 to +0.09999 Specify temperature coefficient

Format :temp:rjunX:real:tco <n>
where; X = 1 to 5 (reference junction #)
Defaults Power-up Saved power-on setup
*RST 0.01 temperature coefficient
:SYSTem:PRESet 0.01 temperature coefficient
Query :TCOefficient? Query temperature coefficient (TC)
:TCOefficient? DEFault Query *RST default TC
:TCOefficient? MINimum Query lowest allowable TC
:TCOefficient? MAXimum Query largest allowable TC
Short-form format: :temp:rjunX:real:tco?
:temp:rjunX:real:tco? def
:temp:rjunX:real:tco? min
:temp:rjunX:real:tco? max
where; X = 1 to 5 (reference junction #)
Response message: -0.09999 to +0.09999
Description This command is used to specify the temperature coefficient (TC) of the “real” temperature ref-
erence junction. TC is specified in °C/volt and is not affected by the :UNIT :TEMPerature com-
mand. The :ACQuire command can then be used to acquire the reference temperature.
Programming example 10 OUTPUT 716; “:temp:rjun1:real:tco 0.05; tco?”
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Two commands in this program message; the first specifies a TC of 0.05 for reference
junction #1, and the second queries the TC.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the TC (0.05).
