The following example for a K typing input (1) from 200 to 1300°C.
• The temperature of the object is obtained.
At room temperature ((B) = 25°C),
the Controller reading is
Near the SP ((B) = 550°C),
the Controller reading is
• In this case, the input correction values are obtained as follows:
Input Value 1 for Input Correction = Controller reading (A) = 40.0 (°C)
Input Correction 1
= Temperature of object (B)
= 25 40 = 15.00 (°C)
Input Value 2 for Input Correction = Controller reading (A) = 500.0 (°C)
Input Correction 2
= Temperature of object (B)
= 550 500 = 50.00 (°C)
