CROSS LINE LASER
Check of vertical line
Use a plumb bob as a reference of a vertical line. Place the instrument
at distance of 1,5m from the plumb bob.
1. Unlock the compensator, switch on the vertical laser line and align it
with the low point of plumb bob.
2. If deviation between the laser line and the plumb bob line exceeds
±0.2 mm per 1m of the plumb bob length (for a 2.5m plumb bob
deviation shouldn’t exceed 0.5 mm) please contact service center.
3. Turn the instrument by 180° and align the vertical laser line with the
low point of plumb bob once again.
