Leveling staff for laser levels ADA Laser Staff - 100% analogue of geo-Fennel TN-20K with a level and a cover. Length ndash; 2.4 m. Weight ndash; 0.9 kg. Scale with division of units of measure in mm, division of units of measure in cm plusmn; 50. Used with the receiver when working with both laser rotational levels and plane builders. This leveling staff makes it much easier to work with a laser receiver and a laser level when leveling floors, unlike a traditional leveling staff. The last additional photo shows the method of working with this leveling staff: The leveling staff is divided into two sections - the bottom one, which shows the numbers (the total height to the "0" mark on the top of the staff is shown on the bottom of the staff - this is the last number directly below the top section) and the top one with a zero mark and a negative-red scale and a positive scale for measuring excesses in millimeters relative to the base point. We install the laser radiation receiver on the block moving along the upper part of the leveling rail so that the receiver mark quot; 0quot; matched with quot; 0quot; number on the top of the rack. Now we turn on the laser level and at the base point (relative to which we will measure the rest) and extend the lower part of the rail just enough so that the fixed receiver catches the beam exactly at quot; 0quot. This will be the zero mark and the first image of the rail in the photo with the number quot; 0quot. Let''s go to another point. Now we just move up the moving part with the receiver until the moment when the receiver again accurately catches the horizontal. The number on the top rail will be the difference in millimeters with respect to the base plane - in our case, the point is lower by 30 millimeters = quot; -30quot. Let''s move on to the next point. Again we move the moving part with the receiver along the upper part of the rail and fix the new result quot; + 47quot; - this means that the second point is 47 millimeters higher than the base point and must be lowered. Comes with a soft carrying case.
