Video Signal
If a surface of the target
lies outside the measu-
ring range, the controller
will send only one signal
for the distance, intensi-
ty and center of gravity.
This may also occur if
a signal is below the
detection threshold. Two
boundary surfaces are
active when the thick-
ness of a transparent
material is measured.
As a result, two peaks
are visible in the video
signal.
