and the horizontal reference line are parallel, i.e. parallel error, please calibrate as the follow methods:
Note: observe whether there is error between the horizontal laser line and the adjacent light ruler reference.
If there is error, please calculate the error into the reference on the wall. (if the adjacent light ruler laser line
locates on +2, the laser line on wall reference locates on +2 too, it means the laser line is in horizontal in this
direction, there is no need calibration.)
2.2.1.1.1 If the excursion is not more than 10mm, adjust the adjusting screw in two self check hole on point A
on the housing of the instrument (figure 3), make the horizontal laser line is coincident with the reference
line.

2.2.1.1.2 If the excursion is more than 3mm, disassemble the housing parts
，
disassemble the screws at B

,add weight stack
（
when horizontal line is lower than the reference

,remove the weight stack
（
when the horizontal line is higher than the reference
） ，
keep the horizontal line in a distance range of 10mm
to the reference line, and adjust 3 fine adjusting screw at C finally to make the horizontal line superposition
with the reference line.
2.2.2 Gradient error
As showed in Fifure 4, the laser line is incline to the reference line, this kind of error called gradient error
