■Procedure for executing the sensor correction (one-point correction) (when using a program)
Configure the setting by the following procedure:
1.
Set 'Sensor correction function selection' (Un\G564) to Normal sensor correction (one-point correction) (0). ( Page
311 CH1 Sensor correction function selection)
2.
Set a value for 'CH1 Sensor correction value setting' (Un\G565). ( Page 312 CH1 Sensor correction value setting)
Sensor two-point correction function
With this function, an error between the temperature process value (PV) and the actual temperature between the two points
selected in advance (a correction offset value and a correction gain value) is stored. Based on this gradient, the error between
the temperature detected by a sensor and the actual temperature is corrected.
Configure the sensor two-point correction setting in the setting mode ('Setting/operation mode status' (X1): OFF). Set
"Monitor" for "Stop mode setting" of "Control basic parameters" in "Application Setting."
