THERMOCOUPLE INPUTS AND CONFIGURATION JUMPER (JP5)

In its base configuration, the T400 analyzer does not include any thermocouple sensors;
however, in instruments where the optional metal wool scrubber (OPT-68) is installed,
one thermocouple is used to sense the temperature of the scrubber. By default, this single
thermocouple input is plugged into the TC1 input (J15) on the relay PCA. TC2 (J16) is
currently not used.
