Thermocouple Input
Make thermocouple connections as illustrated below. Connect the positive lead of the
thermocouple to terminal 3, and the negative to terminal 1. For industrial environments with
comparatively high electrical noise levels, shielded thermocouples and extension wire are
recommended. Be sure that the input conditioning jumpers are properly positioned for a
thermocouple input. See Appendix A-2 (page 64) and A-3 (page 65 or 66).
