5.3 CJC Thermocouple Installation
When using thermocouples it is necessary to install the supplied Cold Junction Compensation thermocouples to
meet temperature accuracy specification. There are two CJC sensors, on located on the top of the terminal
block, the second located at the bottom of the terminal block. The CJC sensors are premounted on a small
circuit board to ease installation. To install the sensors unscrew terminal pairs 2/4 and 37/39 and slide the CJC
sensors under the screws. Tighten the screws to no more than 10 lbs. in. of torque.
