In case of the thermocouple input (KR21*0 and KR21*1 are same connection)
CH1, CH6, CH12 are the channels for adjustment.
For the adjustment of thermocouples, connect to the CH1, CH6, CH12 independently as shown in the
right figure.

The electromotive force of the thermocouple input becomes small by the electromotive force equivalent
to the temperature at terminals. The instrument itself compensates for its value. This is called the
reference junction compensation. The input for the adjustment is entered with the power of a reference
unit (0°C at reference). Accordingly, the reference junction compensator is used for reducing the
reference junction compensated value.

CH1,CH6,CH12 are used for adjusting 3
elements for measuring the terminal
temperature.
■
Use only CH1,CH6 for 6 channels specification
