1.Characteristic
Alarm function beyond the safe range.
-----Magnetic damping compensation system ensures fast leveling time;
-----The line can be divided into three gears: horizontal,vertical and cross.The vertical line can extend over the zenith.
-----The laser point to the ground can be used for machine positioning (line 2 machine does not include the point to the ground).
-----360 degree rota-table base, equipped with fine adjustment structure,can makethe machine quickly find the target.
-----The working height of the machine can be adjusted arbitrarily with the tripod(with optional accessories).
2.Functions
-----The horizontal line can be drawn on the wall.
-----The vertical line can be drawn on the wall, and the cross line can be drawn to the ceiling.
-----The laser point to the ground is precisely located by the machine.

3.Emission diagram of 3D level:
Move the measuring instrument to the pipe wall B (no need to rotate the measuringinstrument), start the measuring instrument and make the instrument level.
Adjust the height of the measuring instrument (with the help of tripod, if necessary,use cushion block) so that the intersection of laser lines is accurately projected onpoint ll of wall B.
Rotate the measuring instrument 180 degrees, butdo not change the height of the measuring instrument, adjust the measuring instrument, let the laser line in the vertical direction pass through point 1 of wall , let the measuring instrument level, and make a markon the inter section point of the laserline of wall a (point lll).
The difference d between point 1 and pointll of wall a is the actual height deviation of themeasuring instrument.
Rotate the measuring instrument 180 degrees, but do not change the height of themeasuring instrument，adjust the measuring instrument,let the laser line in thevertical direction pass through point 1 of wall , let the measuring instrument level,and make a mark on the intersection point of the laser line of wall a(point lll).
The difference d between point 1 and point lll of wall a is the actual heightdeviation of the measuring instrument.
You can use the following formula to calculate the maximum allowable deviation, D-max/D-max = twice the wall spacing x0 2mm/m.
Example: if the distance between walls is 5m, the maximum allowable deviation D-max = 2x5m x 0.2mm/m = 2mm.So the distance between marks should not exceed2mm.
