Note!
You must perform an air set before installing the sensor. To do so, refer to the chapter
"Calibration".

Calibrat
When commissioning inductive sensors,
an airset is mandatory.
The calibration of the sensor is to be
performed in air. The sensor must be dry.
Remove sensor from the medium and dry

Note!
This section decribes the calibration for temperature compensated
conductivity. For calibration with uncompensated conductivity, set the
temperature coefficient
α
to 0.
The sensor should be immersed at a
sufficient distance from the vessel wall
(installation factor has no influence if
a > 15 mm / 0.59").
