SELF-INSPECTION OF
THE ACCURACY
1. 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
correct.
2. 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 upper 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.
3. 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 covered the marked point B after
EN
auto-leveling finished. Rotate the instrument and aim
it to wall W1, after auto-leveling finished, 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 horizontal 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.
4. 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 on the wall.
3)
Adjust the instrument, make the vertical laser line V2
covered with the line and pass through the marked
point B after auto-leveling finished.
4)
Mark a point on the vertical laser line V1 on the wall as
C in the same height position with the marked point.
5)
Measure the height difference as H between two
marked points A and C.
