Device usage
▪
Identify the target to be monitored.
▪
Ensure that the tripod is properly balanced and set up on solid ground. A ballast can be suspended from the tripod
to stabilise it. Adjust the height of the tripod if needed.
▪
Aim the laser beam on the selected surface by using the scope.
The laser only functions on a non-transparent surface.
It's best to select a flat surface with a light grey colour.
▪
Check the distance indicated on the display. To obtain the best performance, it is recommended to place the
laser less than 50 m (164ft) away from the structure. Try as much as possible to position the laser beam
perpendicular to the targeted surface.
▪
When selecting the unit of measurement, it is possible to change from the metric to imperial system and vice
versa
(see §5.1)
.
▪
Select the detection threshold using the buttons ranging from
2 to 100 mm (0.1” to 4”).
▪
Using the selected threshold, monitoring is activated after 2 seconds to avoid button pressing causing a
movement detected by the laser range finder. Check that the flashes are blinking:
