CJC is performed by default by taking the CJC sensor temperature value for a given channel, converting that to a thermocouple voltage, and adding that
voltage from the measured value before converting to a user value. If this bit is set for a given channel, the signal value is directly converted to a user value
(No cold junction compensation performed).
Wire &
CLCD
Use to set the wire mode. The combination of values in bits 14 and 15 determine the mode, as listed in the following table.
TU Chx Use to set the temperature units.
0 = Degrees Celsius
1 = Degrees Fahrenheit
