To check the accuracy of line laser level
To check the accuracy of line laser level (slope of plane)
Set up the instrument between two walls, the distance is
5m.Turn on the Cross Line Laser and mark the point of cross
laser line on the wall.
Set up the instrument 0,5-0,7m away from the wall and make,
as described above, the same masrks. If the difference {a1-
b2} and {b1-b2} is less then the value of “accuracy” (see spe-
sifications), there is no need in calibration. Example: when
you check the accuracy of Cross Line Laser the difference
is {a1-a2}=5 mm and {b1-b2}=7 mm. The instrument’s error:
{b1-b2}-{a1-a2}=7-5=2 mm. Now you can compare this error
with standard error. If the accuracy of Cross Line Laser isn’t
corresponding with claimed accuracy, contact the authorized
service center.
To check level
Choose a wall and set laser 5M away from the wall. Turn
on the laser and cross laser line is marked A on the wall.
Find another point M on the horizontal line, the distance is
around 2.5m. Swivel the laser, and another cross point of
cross laser line is marked B. Please note the distance of
3
B to A should be 5m. Measure the distance between M to
cross laser lune, if the difference is over 3mm, the laser is out
of calibration, please contact with seller to calibrate the laser.
To check plumb
Choose a wall and set laser 5m away from the wall. Mark
point A on the wall, please note the distance from point A
to ground should be 3m. Hang a plumb line from A point
to ground and find a plumb point B on ground. Turn on
the laser and make the vertical laser line meet the point B,
along the vertical laser line on the wall and measure the
distance 3m from point B to another point C.
Point C must be on the vertical laser line, it means the
height of C point is 3m. Measure the distance from point
A to point C, if the distance is over 2 mm, please, contact
with seller to calibrate the laser.
Care and cleaning
Please handle measuring instrument with care. Clean with
soft cloth only after any use. If necessary damp cloth with
some water. If instrument is wet clean and dry it carefully.
Pack it up only if it is perfectly dry. Transport in original con-
