S Set operation for Type S thermocouples
B Set operation for Type B thermocouples
N Set operation for Type N thermocouples
:TYPE? Query thermocouple type
This command is used to configure the Model 2002 for the thermocouple type that you are using
to make temperature measurements. See paragraph 2.4.5 (SENSOR) for more information.
PRINT #1, "output 16; temp:tc:type k; type?" ' Specify TC type
PRINT #1, "enter 16" ' Get response from 2002
:RJUNctionX commands
Where; X = 1 to 5 to specify reference junction.
These commands are used to configure the specified reference junction for thermocouple tem-
perature measurements. Typically, each thermocouple switching card uses a single reference
junction. See paragraph 2.4.5 (REF-JUNCTIONS) for more information
:RSELect <name>
[:SENSe[1]]:TEMPerature:RJUNctionX:RSELect <name> Specify reference junction type.
<name> = SIMulated Use simulated temperature as reference
REAL Use a measured temperature as reference
:RSELect? Query reference junction type
This command is used to specify the type of reference junction that is going to be used for ther-
mocouple temperature measurements. Specify REAL if using an actual reference junction. The
:REAL:TCoefficient command is then used to specify the temperature coefficient of the refer-
ence junction.
Specify SIMulated if you wish to use a simulated reference temperature. The :SIMulated com-
mand is then used to specify the desired simulated reference temperature.
PRINT #1, "output 16; temp:rjun1:rsel sim; rsel?" ' Specify reference
PRINT #1, "enter 16" ' Get response from 2002
:SIMulated <n>
[:SENSe[1]]:TEMPerature:RJUNctionX:SIMulated <n> Specify simulated reference temperature
<n> = 0 to 50 Specify temperature in °C
32 to 122 Specify temperature in °F
273 to 323 Specify temperature in K
DEFault 23°C, 73°F, 296K
MINimum 0°C, 32°F, 273K
MAXimum 50°C, 122°F, 323K
:SIMulated? Query simulated reference
:SIMulated? DEFault Query default *RST reference
:SIMulated? MINimum Query lowest allowable reference
:SIMulated? MAXimum Query largest allowable reference
This command is used to specify the simulated reference temperature. The temperature value
depends on which temperature scale is currently selected (°C, °F or K). Typically, 0° or 23°C is
used as the simulated reference temperature.
