Sensor-type
Procedure for checking the calibration
pH
Immerse sensor in both calibration liquids
Redox
Connect the Null- plug (= 0 mV), then reconnect the sensor and dip into the
calibration liquid
Conductivity
Place sensor in air (0 mS), then immerse sensor in calibration liquid
Oxygen
Disconnect the sensor plug (0%), then reconnect the sensor and hold it just
above the water surface (102%)
If the calibration fluids have different temperatures than the water measured for the
temperature compensation, the displayed values may deviate from the actual values.
Use the sensor for controlling tasks only when the correct function and calibration
have been proved without any doubts!
