appropriate when it is no longer possible to work with thebeam catcher (e.g. unfavourable light conditions).

7.3 Working with beam catcher

Scanning function

Moving it slightly, hold the beam catcher (PA 331/341)in the rotating laser beam for less than 5 seconds orcontinuously. The laser will follow the catcher as it isguided by hand or move in the range from about 150 toabout 1400mm (depending on the intervening distance)around it. The catcher will make the beam appear muchbrighter.

Smart Scan function

Hold beam catcher (PA 331/341) still in the rotatinglaser beam for longer than 5 seconds.

+ Stop Laser LineThe laser beam will stop at the chosen point and projecta line with a lenght of 150 - 2000 mm (depending on theintervening distance) across the beam catcher. Thisleaves both hands free for installation work.
