Chapter 5 Thermocouple Input Module (XBF-TC04S,TC04B)
5.3.2 Scaling function
Thermocouple input module has a function to scale value in user-defined range besides temperature
display.
The scope is classified into two types; 16 bits data type, -32768~32767 and 16 bits data type without
mark, 0~65535.
If a user selects one of these two types and sets the range, it displays the temperature through scaling
operation.
Scaling data type Scaling min. value Scaling max. value
Signed value -32768 ~ [Scaling max. value -1] [Scaling min. value+1] ~ 32767
Unsigned value 0 ~ [Scaling max. value-1] [Scaling min. value+1] ~ 65535
The following graph indicates relation between scaled value and temperature input.

X1 = Thermocouple measurement max. temperature value
Y0 = Scaling min. value
Y1 = Scaling max. value

Ex.) If scaling with mark is set with -2000 ~ 13000 and the temperature measured K type sensor is
500.0 ℃, the value scaled is as follows.
