10 X axis scaling: The total signal is zoomable with the slider on the left side during
running measurement. The time range can be defined in the input field below the
time axis. Once the diagram is stopped, you can use the right slider as well. The
You may also move the zoom window sideways with the mouse in the center of the
zoom window (cross arrow).

In the state of active triggering, see figure, a trigger
impulse is required that sets off the video signal.
This indicates the display at the top right in the
window. The status display may nevertheless be
green.

Thickness Measurement of Transparent Objects
In Thickness Measurement mode, the controller evaluates two signals that reflect from
the surface. The controller uses the two signals to calculate surface distances and thick-
ness.
Align the sensor vertically to the target object. Ensure that the target is located near
the midrange (= SMR + 0.5 x MR).
i
The light beam must meet the target surface at a right angle to avoid inaccurate
measurements.
