The :ACQuire command is then used to store the simulated reference temperature.
PRINT #1, "output 16; :unit:temp c" ' Select °C temp scale
PRINT #1, "output 16; temp:rjun1:sim 0; sim?" ' Set reference for 0°C
PRINT #1, "enter 16" ' Get response from 2002
:TCOefficient <n>
[:SENSe[1]]:TEMPerature:RJUNctionX:REAL:TCOefficient <n> Specify temperature coefficient
<n> = -0.09999 to +0.09999 Specify temperature coefficient
DEFault +0.01 temperature coefficient
MINimum -0.09999 temperature coefficient
MAXimum +0.09999 temperature coefficient
:TCOefficient? Query temperature coefficient (TC)
:TCOefficient? DEFault Query *RST default TC
:TCOefficient? MINimum Query lowest allowable TC
:TCOefficient? MAXimum Query largest allowable TC
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.
PRINT #1, "output 16; temp:rjun1:real:tco .05; tco?" ' Set temp coefficient
PRINT #1, "enter 16" ' Get response from 2002
:OFFSet <n>
[:SENSe[1]]:TEMPerature:RJUNctionX:REAL:OFFSet <n> Specify voltage offset
<n> = -0.09999 to +0.09999 Specify voltage offset at 0°C
DEFault 0.01V offset
MINimum -0.09999V offset
MAXimum +0.09999V offset
:OFFSet? Query voltage offset
:OFFSet? DEFault Query *RST default voltage offset
:OFFSet? MINimum Query lowest allowable voltage offset
:OFFSet? MAXimum Query largest allowable voltage offset
This command is used to specify the offset voltage at 0°C for the specified reference junction.
PRINT #1, "output 16; temp:rjun1:real:offs .05; offs?" ' Set voltage offset
PRINT #1, "enter 16" ' Get response from
2002
:ACQuire
[:SENSe[1]]:TEMPerature:RJUNctionX:ACQuire Update reference temperature
This action command is used to update the stored reference temperature (Simulated or Real) for
generating a temperature measurement.
PRINT #1, "output 16; ":temp:rjun1:acq" ' Update reference temperature
