Description 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.
The :ACQuire command is then used to store the simulated reference temperature.
Programming example 10 OUTPUT 716; “:unit:temp c”
20 OUTPUT 716; “:temp:rjun1:sim 0; sim?”
30 ENTER 716; A$
40 PRINT A$
50 END
Line 10 Selects °C temperature scale.
Line 20 Two commands in this program message; the first programs reference junction #1 for a 0°C
simulated reference temperature, and the second queries the simulated reference temperature.
Line 30 Addresses the Model 2001 to talk.
Line 40 Displays the simulated reference temperature (0)

:temp:rjunX:real:tco? def
:temp:rjunX:real:tco? min

Description This command is used to specify the temperature coefficient (TC) of the “real” temperature reference
junction. TC is specified in °C/volt and is not affected by the :UNIT :TEMPerature command. The :AC-
Quire command can then be used to acquire the reference temperature.
