TB82PH ATEX Product Instruction Manual
CALIBRATE MODE
Before an instrument can properly measure pH the sensor must be calibrated to the instrument.
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.
