Engineering Inspection foot usage, Jinke instrumentation (certified), engineering inspection by foot Instrument Co., Ltd. Qingdao Branch. Instrument Co., Ltd. Qingdao Branch (www.qdjk17.com) is specialized in the "mapping equipment, analysis equipment, testing equipment, flow meters, optical instruments, temperature instruments," the enterprise, the company adhering to the "honesty, hard service" philosophy, to provide you with the highest quality products and services. Welcome to inquire! Contact: Li Yongjie. Product Applications: DZJ-300A can be widely used in building 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 dot laser ◆ vertical quasi visible through a telescope eyepiece can be directly observed clearly visible laser engineering inspection feet, no harm to the eyes. Laser pointing 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, optional laser plummet device. The use of laser vertical collimator 1. placement, alignment, leveling the tripod placed on the station, the instrument installed in the base of the tripod center hole to force special instrument engineering test foot, lock base clamp knob, instrument firm . Adjust the height of the tripod, the telescope eyepiece roughly human eye contour. Open-to-point laser switch, adjust the focusing knob on the spot, the laser is focused on the test site. Adjusting the tripod, so the bubble is centered round blisters. Turn the instrument alidade so long vial with screw connection of any two legs parallel to the opposite direction the same amount of swirling spiral Jinke two feet engineering inspection feet, the bubble is centered. The instrument alidade turned 90 ?, the third leg swirling spiral, the bubble is centered. Using the above method repeatedly adjusted until the instrument is rotated to any position, the bubble does not exceed one quarter of the maximum deviation from the grid value. The instrument alidade rotated 180? In the case of engineering inspection and examination of the entire foot sales, if any deviation from, loosen the central screw, the head of the entire instrument rack pan, until the laser spot and the station precise alignment. Rotate the alidade, confirm that the instrument is rotated to any position, long spirit level bubble is centered, if deviated, repeat the above steps. Confirmation, and after leveling is completed, will point the laser turned off to save electricity. 2. Place the grid laser sighting target at the target. Rotate the telescope eyepiece reticle crosshairs make clear, then turn the focusing knob on 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 difference. 3. A. upward vertical quasi-optical vertical quasi If the instrument is calibrated when the instrument after leveling, collimation axis coaxial with the vertical axis error ≤5 °, can be used as vertical alignment, one observation can ensure vertical quasi accuracy. However, in order to improve the vertical quasi precision instrument alidade should be rotated 180 ?, get a second observation through a telescope, whichever number (midpoint) of the measured value. B. Laser Verticality
