Configuration
The following information explains the various configuration options for temperature mea
surements. To select and configure the thermocouple measurement:
Press SHIFT then TCOUPL. Three choices are available using the and keys:
• UNITS — C, K, F (Centigrade, Kelvin, Fahrenheit). This parameter selects the dis-
played units for temperature measurements.
• TYPE — J, K, T (thermocouple type).
• JUNC — SIM, CH1 (simulated or referenced at Channel 1). Typically, a thermocou-
ple card uses a single reference junction. The Model 2000 can simulate a reference
junction temperature or use the reference junction on a switching card. Typical ref
-
erence junction temperatures are 0°C and 23°C.
A simulated reference temperature is the temperature of the junction where the thermo-
couple voltage is sensed. It is room temperature if the thermocouple wire is terminated to
banana jacks and corrected directly to the multimeter. The accuracy of a temperature mea
-
surement depends on the accuracy of the reference junction.
