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 displayed
units for temperature measurements.
• TYPE — J, K, T (thermocouple type).
• JUNC — SIM, CH1 (simulated or referenced at Channel 1). Typically, a thermocouple
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 reference junction
temperatures are 0°C and 23°C.
A simulated reference temperature is the temperature of the junction where the thermocouple
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 measurement depends
on the accuracy of the reference junction.
