Thermocouple (TC) connections

Attach the TC wires to the applicable TC mini-connector
(Figure 9). The wider blade is the negative. Then attach the
connector to the instrument.

Measure/simulate a Thermocouple

To measure/simulate the TC values:
1. Connect the instrument (Figure 9) and, if necessary,
adjust the Set Up (Table 1).
2. Select the task from the task selection menu (Table 2).
3. Select Settings ( ) to change the operation from
Temperature to mV or mV to Temperature.
4. If necessary, adjust the Settings (Table 4/5) and/or the
output values to the system (Table 7).
