THERMOCOUPLE CONNECTIONS Simulating or reading thermocouples requires the use of thermocouple or extension grade thermocouple wire. Plug thermocouple wires into the miniature thermocouple jack or place bare thermocouple wires onto the brass block under the screws. The CL543B has two banana jacks (1+ and 2-) mounted in the top end of the housing. These are not temperature compensated and are to be used only for millivolt signals. 1 Screw terminal for thermocouple wire plus miniature thermocouple
