CALIBRATE MODE
Before an instrument can properly measure pH the sensor must be calibrated to the instrument. Periodic update
calibrations must be performed during the time the sensor is in service. The frequency of re-calibration is application
dependent. This mode also defines calibration of the temperature input and fine tuning the 4-20 mA output for non-
fieldbus versions.

Caution.
The Reset Calibrate State will reset all
calibration values; therefore, the process sensor
and temperature sensor will require calibration
after performing the Reset Calibrate procedure.
