2. Indication accuracy of thermocouples
• 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 re-
pair, always return the Unit and the terminal block (with the cold-junc-
tion compensator) as a set.

The heater burnout detection function will not
operate if the set value is set to 0.0 A or 50.0 A.
(When the SV is 0.0 A, the heather burnout alarm
will be OFF. When the SV is 50.0 A, the heater
burnout alarm will be ON.)
