*1: Calculate the accuracy in the following method.
(Accuracy) = (conversion accuracy) + (temperature characteristic) (operating ambient temperature
variation) + (cold junction temperature compensation accuracy)
An operating ambient temperature variation indicates a deviation of the operating ambient
temperature from the 25 5
range.
Example: When the thermocouple used is B, the operating ambient temperature is 35 , and
the measured temperature is 1000 , the accuracy is:
( 3.5 ) + ( 0.4 ) (5 ) + ( 1 ) = 6.5
