 Select Temperature sensor or Aquarium temperature manual for temperature
compensation ->RETURN.
 If you selected the Aquarium temperature manual enter the basin temperature
->RETURN
 Specify the temperature of the calibration liquid ->RETURN
 Hold the sensor in the air (Hold the sensor in the air!) until a signal sounds
 Then immerse the electrode in the calibration liquid corresponding to the Measuring
range ->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 Conductivity sensor is now ready for use. Based on your calibration, ProfiLux 4 can
determine the Conductivity.
5.9.8 Oxygen Sensor
In contrast to all other sensors, the oxygen sensor is calibrated in 2 steps. The first
calibration is the so-called Null-calibration. The second calibration is the so-called Air
calibration.
There must be a time interval of at least 30 minutes between both calibrations, as
otherwise sensible values cannot be determined.
This means that the calibration process must be started two times:
During the calibration, you will be asked for how ProfiLux 4 is to perform the Temperature
compensation and the Salinity compensation. ProfiLux 4 offers you two options:
 Aquarium temperature manual: The temperature compensation is carried out by
means of a fixed set temperature (Aquarium temperature manual). Then enter the
temperature.
 Aquarium temperature by using a continuously measured value: Select the desired
temperature sensor for temperature determination.
 Salinity manual: The salinity compensation is carried out by means of a fixed set
salinity (Salinity manual). Then enter the salinity. For freshwater, please enter 0.0
 Salinity by using a continuously measured value: Select the desired Conductivity sensor
(only sea water possible) for the determination of the measured value
The temperature of the air at the calibration site (above the water surface) is also required.
Then the calibration starts.
