Laser Level Application: DZJ-300A can be widely used in construction, engineering, installation, project supervision, deformation observation. Such as: high-rise buildings, elevators, mines, water towers, chimneys, installation of large equipment, aircraft manufacturing, shipbuilding and other industries. Features: ◆ outgoing laser brightness can be adjusted depending on the usage environment can adjust the brightness of the laser spot ◆ vertical quasi visible through a telescope eyepiece laser can be directly observed clearly visible laser, no harm to the eyes. Laser point to the effective distance of 100 meters. ◆ machine professional waterproof dustproof and waterproof design, completely avoid the rain caused by moisture inside the instrument, the whole dust and waterproof rating to IP54 ◆ Optional laser plummet Standard preparation for the optical plummet, and optional laser plummet device. Engineering Test-foot vertical degree is mainly used to detect the object plane; vertical deviation degree (walls, door frames decorative veneer) and other projects, levelness and flatness of any plane. Vertical detection: the detection scale for deployable structure, close surveying instruments offer one meter long, two meters long to start. Flatness detection: foot side abutting the test surface, the gap size scale detection plug its value that flatness deviation. Level detection: detecting foot side with vial, detectable levels of degrees, use the same general level meter. The main technical parameters (8 paperback) No. Name Range Accuracy 1. Vertical error detection scale 2000 × 55 × 25 ± 14/2000 ± 0.5 2. detect foot diagonal 970 × 22 × 13 1000-2420 (ruler) ± 0.5 3. Multi-function inside and outside the right angle detection scale 200 × 130 ± 7/130 0.5 4. cursor feeler 150 × 15 × 17 1-15 0.5 5. one hundred grid 240 × 115 ×× 3 standard brick 0.5% 6. reel 65 × 65 × 20 15m 7. mirror 110 × 65 × 15 8. drum sound hammer 25g laser vertical collimator 1. placement, alignment, leveling the tripod placed on the test site, the instrument is installed in the base of the tripod mandatory center hole, locking base clamp knob, the instrument stable. Adjust the height of the tripod, the telescope eyepiece roughly human eye contour. Open to point the laser switch, adjust the hand wheel on the spot focusing the laser is focused on the measurement site. Adjustable tripod, so the bubble is centered round blisters. Turn the instrument alidade so vial with screw connection between any two feet parallel, the same amount in the opposite direction rotating two leveling screws so that the bubble is centered. The instrument alidade rotated 90 ?, swirling spiral third leg, the bubble is centered. Using the above method repeatedly adjusted until the instrument is rotated to any position deviation does not exceed the maximum bubble fourth grid value. The instrument alidade rotates 180? Inspection of the circumstances, if any deviation from the mapping equipment, loosen the center screw, the entire instrument in domestic mapping equipment rack pan head, until the laser spot and precise alignment of the station. Turn the alidade, confirm that the instrument is rotated to any position, long level is centered, if deviation, repeat the above steps. After confirmation, the leveling completion of an optical surveying instruments, you can point the laser will be shut down to save electricity. 2. Place the grid laser sighting target at the target. Turn the telescope eyepiece reticle crosshairs makes clear, then turn the focusing knob in the laser target reticle clear imaging, and try to eliminate parallax, that is, when the observer moves slightly sight, there can be between the reticle and the target significantly offset. Otherwise, you should continue to ignore the above steps until the poor. 3. A. upward vertical collimator optics vertical quasi If the instrument has been calibrated, when the instrument is leveled, the collimation axis coaxial with the vertical axis error ≤5 °, can be used as vertical alignment, a prospective observational ensure vertical accuracy. However, in order to improve the vertical quasi-precision instrument should be rotated 180 ?, alidade get a second observation through a telescope, whichever number (midpoint) of the measured values.
