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.
