How to use laser level!

 

      Laser Level, also known as inkline instrument, probation is the same as the previous ink fountain, the second is the decoration plan straight line and vertical line, the instrument placed in the center of your line to be adjusted to the extent that the boot, and then open the degree and Vertical line (H / V key), and then according to the wall according to the line to construction on it!
      When measuring the level instrument task surface close to the measured appearance, until the bubble full of movement can stop reading. The graduation value of the graduation meter is a graduation on the basis of one meter. To measure the practical graduation length of L, the argument of the contestant can be stopped by the following formula: Practical graduation value = graduation value * L * Because the degree of instrument zero banned caused by measurement error, and therefore before the instrument must be zero degree calibration stop or adjust.
Degree meter zero correction, adjustment methods:
      The instrument will be placed on the level of stability, the extent of the plate (or machine rail), until the bubble fluctuations, such as the left end of the reading, and set to zero. Then the degree of instrument turned 180 degrees, still on the tablet's original position, to be bubble after the original, is still the end (left) reading A grid degree instrument zero error of A grid. If the zero error exceeds the allowable limit, you need to adjust the degree instrument zero adjustment parts structure (adjust the screw or nut, zero error reduced to less than the agreed value. On non-regular adjustment of the screw, the nut can not be free to twist. The degree of instrument surface and the tablet must be rubbed Jie clean test after adjustment screws or nuts and other parts must be tightened)
