Calibrating Thermocouples
Calibrate according to the type of thermocouple, thermocouple 1 group (Input
Types 5, 7, 11, 12, 15), and thermocouple 2 group (Input Types 6, 8, 9, 10, 13,
14, 16, 17, 18, 19, 20, 21, 22, 24, 25).
When calibrating, do not cover the bottom of the controller. Also, do not
touch the input terminals (pin numbers 4 and 5 on the 900-TC16, 19 and 20
on the 900-TC8, and 11 and 12 on the 900-TC32) or the compensating
conductor on the controller.
