Laser vertical collimator mainly to check the verticality of the top of the upper and lower laser, and then used in conjunction with laser target distance can be seen up and down the laser and exterior of the building to determine whether the vertical. 150 * 150 empty reserved. Must Zaokong. 5. After pouring ultrasonic range finder, when the upper axis measurements were cast. Set up in the control point on the vertical instrument alignment point upward projection of the laser beam, the laser receiver with top target was accepted. And rotate 360 ??° vertical collimator rangefinder, ... and then turn around, not in the center of the cross, then change the needle with debugging twist wire, which can specifically look for tips while debugging, cross the center of the laser spot close to half the time Infrared from the instrument, turn around in half tone, and so forth can be adjusted. Similarly under the laser spot. Leica laser rangefinder Leica DISTO D2: small partners in the base model compact, easy to carry, designed for indoor applications. Addition and subtraction can be performed and the area and volume through the shortcut keys, measuring fast and very reliable. Before the measurement results can be stored 10 times. As with all Leica laser distance meters, the laser spot which is clearly visible. Even if the target is difficult to access the site, you can always find the target anchor point. Leica DISTO D2 -? You no longer need to use a tape measure to measure up! Accurate measurements: fast and easy - fits any pocket laser vertical collimator performance indicators: Effective range: ≥120m (daytime) ≥250m (night) exit power: 1mw point under the minimum focusing distance: 0.5m Effective aperture: 36mm Magnification: 25X Field: 1 ° 50 'Imaging: As Minimum sight distance: 0.8m wavelength: 635nm Power: 2 AA alkaline batteries wavelength: 635nm spot diameter: ≤3mm / 50m FOV: 5 ° Imaging: Just as Magnification: 3X Focus Range: 0.5 ~ ∞ electronic rangefinder, Jinke instrumentation (certified), rangefinder provided by Qingdao Branch of the Instrument Co., Ltd.
