Self-inspection of the accuracy
I. Plumbing dot detection
1. Mount the instrument on a tripod and raise to 1m in height.
Then mark the spot position of plumbing dot.
2. Turn the machine 90° clockwise by three times, and mark
the spot positions of plumbing dot respectively.
3. Measure the maximum spacing H among the four marked
points.
4. Hmax= tool height (m) × nominal accuracy of plumbing dot
(mm/m) × 2
5. If H≤Hmax, the level accuracy of the plumbing dot is cor-
rect.
II. Vertical laser line detection
1. Find a transparent door opening. Open the door, put the
instrument on any side of the ground 2.5m away from the
door opening. Turn on the instrument and make the vertical
laser line pass through the middle of the door opening.
After auto-leveling finished, mark a point as A on the inner
ground of the door opening, mark a point as B on the up-

10
EN
per position of the door opening, mark a point on the laser
line as C on the other side of the ground which is 5m away
from the instrument.
2. Move the instrument to the marked point C. Adjust the
vertical laser line to make it pass through the marked points
A and C at the same time after auto-leveling finished. Mark
a point on the laser line as D on the upper position of the
door opening.
3. Calculate the distance between B and D as H.
4. Hmax= height of door opening (m) × nominal line accuracy
(mm/m) × 2
5. If H≤Hmax, the accuracy of the vertical laser line is correct.
III. Horizontal laser line detection
A. Detecting the contour accuracy of horizontal
laser line
1. Find a room whose size is large than 5m×5m. Mount the
instrument on a tripod, and put the tripod near wall W1
(the distance between them is about 0.5m). Turn on the
instrument, after auto-leveling finished, find the laser line
intersection point on the wall W1 and mark a point as A.
2. Rotate the instrument for 180°, after auto-leveling finished,
find the laser line intersection point on the wall W2 and
mark a point as B.
3. Move the instrument near wall W2 (the distance between
them is about 0.5m), aim the laser line to wall W2 and
adjust the height, make the laser line intersection point cov-
ered the marked point B after auto-leveling finished. Rotate
the instrument and aim it to wall W1, after auto-leveling fin-
ished, make the vertical laser line on wall W1 pass through
the marked point A. Find the laser line intersection point on
the wall W1 and mark a point as C.
4. Calculate the distance between A and C as H.
5. Hmax= nominal line accuracy of distance between wall W1
and W2 (mm/m) × 2
6. If H≤Hmax, the contour accuracy of horizontal laser line is
correct.
B. Detecting the level accuracy of the horizontal
laser line
1. Find a room whose size is large than 5m×5m. Mount
the instrument on a tripod, and put the tripod 5m away
from the front wall and in the middle between the left
and right walls W1 and W2. Turn on the instrument, after
auto-leveling finished, mark two points as A and B on the
horizontal laser line on W1 and W2, make sure the straight
line AB is about 2.5m away from the instrument.
2. Move the instrument 5m in front of the position, and rotate
the instrument, adjust the tripod height to make the hori-
zontal laser line pass through the marked point B on wall
W2 after auto-leveling finished. Find the horizontal laser line
on the wall W1, mark a point on the horizontal laser line as
C on the vertical position of marked point A.
3. Measure vertical height difference as H between two
marked points A and C.
4. Hmax= distance between wall W1 and W2 (mm) × nominal
line accuracy (mm/)× 2
5. If H≤Hmax, the contour accuracy of the horizontal laser line
is correct.
IV. Detecting the 90° orthogonal accuracy
1. Set a 6m long straight line paralleled with a wall which
is 3m away. Fix both two ends of the line and mark two
points as A and B.
2. Put the instrument in the middle of the line. Adjust the
instrument, make the vertical laser line V1 covered with
the line and pass through the marked point A after auto-
leveling finished. Make a point on the vertical laser line V2
