• Accuracy ratings are given for the Temperature Control Unit used in a set with a cold-junction compensator (on the
terminal block). Always use the Unit and terminal block in a set. There are labels with serial numbers attached to
the terminal blocks and Units to help keep track of the sets.
• When returning a thermocouple-type Temperature Control Unit for repair, always return the Unit and the terminal
block (with the cold-junction compensator) as a set.
