If the reference points

Divide the results with twice the value of the room length.
If the result is greater than 4 mm, the device must be

8.3 Checking the perpendicularity of the lateral
axes in a square room
1. Select a room with a square floor plan, in which the walls are
approx. 10 metres apart.
Position the device on a tripod in the middle of the room and
align the vertical laser lines perpendicular to one of the walls.
Mark the centre of the lower plumb beam
on the floor.
Mark the intersecting point
of the vertical and horizontal
laser lines.
Mark the intersecting point
of the vertical and horizontal
laser lines.
2. Rotate the device 90° clockwise.
The lower plumb beam must remain on the marking
and the
left lateral intersecting point must be exactly aligned to the
marking .
Mark the intersecting point
of the vertical and horizontal
laser lines.
3. Rotate the device 90° clockwise.
The lower plumb beam must remain on the marking
and the left lateral intersecting point must be exactly
aligned to the marking
.
Mark the intersecting point
of the vertical and horizontal
laser lines.
