5.9.5 pH Sensor
 Connect the pH sensor
 Set the calibration tolerance
 Determine the Calibration value 1 and then the Calibration value 2 and confirm with
RETURN
 To calibrate the Calibration value 1: Immerse the sensor in the calibration liquid
suitable for your specified calibration value and press RETURN
 Leave the sensor in the calibration liquid until the signal tone
 The sensor is now calibrated to Calibration value 1
 Dry the sensor and continue with the calibration of the Calibration value 2
 If no errors have occurred, save the calibrated values by selecting Yes and confirm
with RETURN
 Check the calibration as described below
The pH sensor is now ready for use. Based on your calibration, ProfiLux 4 can now determine
the pH value.
5.9.6 Redox-Sensor
For the redox sensor calibration, you need a so-called Null-plug, which is supplied with
ProfiLux 4 as well as our redox expansion cards (PLM Redox). The plug must be plugged onto
the sensor connection of the ProfiLux 4 (corresponding white BNC socket on the back of the
housing).
 Set the calibration tolerance
 Determine the Calibration value 2 and confirm with RETURN
 Plug the Null- plug ->RETURN
 Wait for the signal sound
 Disconnect the Null- plug and then connect the Redox sensor ->RETURN
 Immerse the sensor in the Calibration liquid to suit your specified Calibration value -
>RETURN
 Wait for the signal sound
 If no errors have occurred, save the calibrated values by selecting Yes and confirm
with RETURN
 Check the calibration as described below
The Redox sensor is now ready for use. Based on your calibration, ProfiLux 4 can determine
the Redox value.
