6.4.2 Definition of flanks
The edges to be detected are defined as rising or falling flanks.
The position/selection of flanks is defined as first from the left or first from the right.
A rising flank is
•
a flank which runs from far to near
•
a flank which runs from infinity (or nothing) to an object
A falling flank is
•
a flank which runs from near to far
•
a flank which runs from an object to infinity (or nothing)
The point of the flank which is closer to the sensor is always chosen as the measuring value. The border of
the measuring range is not an edge.
6.4.3 Definition of an edge
Edge
An edge is the transition of a stable level (1) inside or outside the measuring range to another stable level (2).
Measurement is always carried out at the level that is closer to the sensor.
The average increase must be greater than ±1.5 mm at 0.5 mm.
