Accuracy Check
Rotate the instrument by 180° so that it points in
the opposite direction 2 to direction 1. Adjust the
instrument so that the laser beam hits point A1
exactly. If point B2 is no further than 2 mm away
from point B1, then the instrument is within tol-
erance.
Should your instrument be outside of the
specified tolerance, please contact a local
dealer or an authorised Leica Geosystems
distributor.
Perpendicularity horizontal points
Place lock switch in "Unlocked" position (see Lev-
elling lock). Mark a reference point (P1) approx.
5m from the walls and position the lower plumb
point exactly on it. Align the cross hair to the left
wall and mark the intersection point (a1) approx.
on the same hight like P1 to the wall. Shortly after
mark the right-hand perpendicular beam (b1) on
the front wall.
Then rotate the device exactly 90° clockwise
around the plumb point P1 and position the left-
hand perpendicular beam to the existing ref-
erence point a1. Make sure that the upper plumb
point is still exactly on the reference P1. Check
afterwards the new reference point b2 with the
old reference b1 on the front wall. The deviation
between the two points may be max. 3mm. Mark
the new position of the right-hand perpendicular
beam to the right wall with c1.
Should your instrument be outside of the
specified tolerance, please contact a local
dealer or an authorised Leica Geosystems
distributor.
Afterwards turn the device exactly 180° around
the plumb point P1 and position the right-hand
perpendicular beam to the existing reference
point a1. Make sure that the upper plumb point is
still exactly on the reference P1. Then mark the
left-hand beam to the right wall and mark it with
c2. Finally measure the difference between the
former reference point c1 and the new point c2.
The deviation may be max. 3mm between these
two points.
