6.3.4 Adjustment with the Video Signal
To simplify the adjustment of the light source and receiver with separate mounting of the
individual components, the display on the controller can show the video signal of the
receiver. This reproduces the brightness trace over the receiver array.
From the main menu, access to the menu
Select options
is obtained by pressing the
key again.
After entry (key ) into this menu, repeated pressing of the key

.
After renewed confirmation with , the video signal appears on the display similar to
the following picture:
Fig. 25 Video signal (correct)
This picture appears with a sensor unit which is very well adjusted. If you now hold a
target object between the light source and the receiver, then its shadow becomes visible
through a fall in the video signal.
The following picture appears, for example, with a poorly adjusted sensor unit:

If after a lengthy period of operation the video signal no longer reaches the maxi-
mum value, it may be due to contamination.
In this case clean the protective windows with a lint-free cloth and some alcohol
(isopropanol).
An optimum video signal , see Fig. 25 , should be able to be obtained by appropriately
moving and tilting the light source and receiver within the permitted tolerances , see Fig.
16 . The curve should be at a maximum and should be symmetrical.
Return to the measurement mode is obtained by pressing the
ESC
key a number of
times.
6.3.5 Options
The set parameters apply independently of the selected measurement program , see Fig.
29 . You will find the standard option in the Appendix under
Option data
, see A 5.5.
The option data in the main memory are used for the measurement mode. This means
that even after quitting the main menu and responding negative to saving the data, the
newly selected option data are valid until the measurement system is switched off. If
no changes are made at all, then no query for saving is presented on quitting the main
menu.
The currently set parameters appear first during selection in the individual menus.
