Sensor Correction Function

When there is an error between the temperature process value (PV) and actual temperature due to measurement conditions,
this function corrects the error. The following two types are available.
• Normal sensor correction (one-point correction) function
• Sensor two-point correction function
• In the Q compatible mode, set a value within the range of -5000 to 5000 (-50.00% to 50.00%) to the full
scale of the set input range.
• When the sensor correction is executed with the engineering tool, the memory having the capacity of
700MB or larger is required. Check the memory in use has the capacity of 700MB or larger and execute the
sensor correction.
Normal sensor correction (one-point correction) function
This function uses the value set in "Sensor Correction Value Setting" in "Application Setting" as the error correction value for
correcting the error.
Ex.
When a value within the range of -200.0 to 200.0 has been set for "Input range setting" of "Control basic parameters" in
"Application Setting," the actual temperature is 60, and the temperature process value (PV) is 58
Set "2" for "Sensor Correction Value Setting" in "Application Setting."
