– Rotate the laser tool 180°. Position it so that the centre of the lower laser
point is on the point II which has already been marked. Allow the laser
tool to level.
Mark the centre of the upper laser point (point III).
– The difference d of both marked points I and III on the ceiling results in
the actual deviation of the laser tool to the plumb line.
In the measuring distance of 5m the maximum permissible deviation is: 5
m x ±0.5mm/mx2= ±5mm.
The difference d between the points I and III can therefore be at most 5
mm.
Always use the centre of the laser line for marking. The width of the
laser line changes with the distance.
Working with the Laser Target (Accessory) (see figures G–H)
With the laser target 21, it is possible to project the laser mark onto the
floor or the laser height onto a wall.
With the zero field and the scale, the offset or drop to the required height
can be measured and projected at another location. This eliminates the
necessity of precisely adjusting the laser tool to the height to be projected.
