Note 1:
For thermocouple inputs with internal cold junction compensation, 1
℃
CJC error
should be taken into consideration. For those with Cu resistor, ice point or thermostat bath
compensation, the accuracy is as above.
Note 2:
Accuracy is not guaranteed between 0 and 600
℃
for type B thermocouple input.
