5.9.7 Conductivity

The conductivity of a liquid is strongly temperature-dependent. For the exact determination

of the conductivity by ProfiLux 4, this results in a so-called Temperature compensation for each

measurement.

During calibration, you will be asked how ProfiLux 4 is to perform the temperature

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.

You will be prompted to enter the temperature of the calibration liquid (Calibration liquid

temperature).

The actual calibration is then started.

Please note the information on the display. After each step, press the RETURN button and

wait for the signal tone before you continue.

 Connect the Conductivity sensor.

 Set the Calibration tolerance ->RETURN

 Determine the Calibration value 2 and confirm with RETURN

Tip

The most accurate values for the conductivity value determination are

obtained by means of a continuously measured value.

Tip

The easiest and fastest way is to equalize the fluid temp is to place the

closed container of the calibration liquid in the aquarium until the

temperature has adjusted. This is only useful if the aquarium temperature

is known.
