Keep in mind that a min. distance must be maintained below the refer
-
ence plane - measurement is not possible here (dead band).
The value
y
states the min. lower value of the measuring range. This
value depends on the medium.
Add the height of the mounting facility
z
and the offset of the medium
y
, to calculate the total range that cannot be measured.
