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 the locking base clamp knob, the instrument stable. Height adjustable tripod laser rangefinder principle, 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 of the ultrasonic range finder, bubble maximum deviation value does not exceed a quarter of the grid value. The instrument alidade rotates 180? Inspection of the circumstances, if any deviation from the range finder, infrared range finder loosen center screw, the head of the entire instrument rack pan, 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. 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. 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. B. laser vertical quasi-direct laser rangefinder to measure the distance: Press the first under the laser (note not facing the eye), targeting and then click to complete the distance measurements. Indirect measurement of distances: can indirectly measure the height of the front wall of the Pythagorean theorem. Measured area / volume: Use the space calculation function can easily calculate the area and volume of space. Splash measure: Thanks to IP54 protection grade design that allows you to operate freely in the construction site in a variety of harsh environments.
