4. DESIGNING THE FIXTURES
(3) Confirming the presence of reflecting light
With the segment set to 1, close the shutter of the emission unit on the X axis,
then check that the reflection light from the Y axis will not be directed into the
reception window of the X axis. Allow 5 to 10 minutes for this check of the
reflecting light as scanning beams from the X axis and the Y axis are
asynchronous.
Under the normal state, the Err-0 message will be displayed.
Perform the same check with the Y axis.
With the oscilloscope connected to the monitor connector on the rear panel of the
display unit, it is also possible to check for the presence of the reception signal
due to the reflection light. For a model with a visible laser beam, the reflection light
can be checked by placing a piece of paper on the reception window.
