10.4.7.3. Thermocouple Inputs and Configuration Jumper (JP5)
Although the relay PCA supports two thermocouple inputs, the current M200EH/EM series analyzers only utilize
one. By default, this single thermocouple input is plugged into the TC1 input (J15). TC2 (J16) is currently not
used. See Figure 11-4 for location of J15 and J16
