Make sure that for all versions a min. distance - the so called
dead zone - below the reference plane is maintained in which a
measurement is not possible. The exact value of the dead
zone is stated in the Technical data in the Supplement.

If the product reaches the transducer, buildup can form on it
over a period of time and later cause measurement errors.
