Averaging
Activation of a smoothing function
The conductivity measurement is influenced by temperature. This influence is compensated automatically or
manually. For manual compensation the temperature is entered manually, for automatic compensation a
temperature sensor must be connected. Compensation is carried out linearly using a temperature coefficient
in %/K which depends upon the composition of the test water.
The capacitance of the sensor cable can lead to a slight deviation of the measurement. This deviation can be
eliminated by cable compensation.
Especially in the lower measuring ranges the measurement tends to get a bit unsteady due to the high
resistance of the water. The signal can be smoothed out by activating an averaging function.
Conductivity sensors are optimized for certain measuring ranges by their geometric dimensions. These
define the cell factor (c value). If you want to use a sensor with a different cell factor or if you want to
calibrate the measurement, adjust the cell factor accordingly.
All these adjustments are part of the basic settings, since they are carried out only once at the beginning.
