This kind of green laser pointer has a keychain for easy carrying

The correct use of the instrument must be noted that the 3.1 3.1.1 before use Please read this manual carefully. 3.1.2 The instrument is a bottom-up vertical collimator, also known as the zenith telescope, that is to launch a point to the zenith of the laser beam. Should be used with the instrument placed in the bottom of the measured target. Instrument installed in front of the card if lying down, need to put up slowly, slowly smoothing liquid compensator; such as the laser spot is not complete, the instrument can be rotated 90 °, and then put up slowly, patiently waiting for the spot as ring. 3.1.3 First tripod support above the ground reference point in the building, and then placed in the instrument tripod. The body color of china laser pointeris white.
The open point the switch, and instrument in the early set level status (ie, the bubble centered in the round blisters), and slowly move the instrument to make the point device to produce the laser beam on the ground reference point. And then tighten the hand wheel, the instrument firmly secured to a tripod. And observe whether the center of the bubble in the circular blisters, if not centered, adjust the hand wheel again, the instrument leveling. 3.2 measurement environment the choice of building vertical collimator measurement, the choice of the measurement environment is very important. In order to avoid deformation of the building due to direct sunlight, the general choice of this period of time between midnight and vertical collimator measurement. The body length of this kind ofchina laser pointeris short.
Should be selected under the conditions of the following wind speed of 3 to 4. LVL 4 Dalian Economic and Technological Development Zone Laser Technology Development Co., Ltd. Dalian Economic and Technological Development Zone Lats Laser Technology Development Co., Ltd. Economic and Technological Development Zone JZC-G manual during deformation observation of the building should be possible to select the same or similar measurement environment, in order to analyze and compare, and must turn to host the diameter measurement, in order to improve the accuracy of the vertical degree of baseline. 3.3 Instrument vertical accuracy of diameter measurement instrument a small amount of change as the ambient temperature changes, the laser beam will drift with the release of the stress of the passage of time and mechanical parts and the errors they cause are regular errors. So that this kind of china laser pointer is portable to carry around easily.
Must make use of this instrument when high-precision measurement of the diameter measurement (such as 0 ° and 180 °), measured at 0 ° for the X0, Y0; measured at 180 ° X1, Y1, obtained two measurements The average, X = error eliminated. 1 1 (X-0 + X 1); Y = (Y0 + Y1). So can layer measurement and the measuring point in the aging drift and ambient temperature of 22 construction of the building process to select 3.4 Building construction process layer measurement and selection of the measuring point during the measurements of the layer by layer, the laser beam is the baseline, the two-dimensional measurement shimmer target should be fixed on the measuring point of the deformation observed. Host will be placed in a fixed observation point (usually a fixed point of the first floor foundation) to be marked; adjust the blisters to a central location, open the host switch and the switch to the point, to point the spot coincide with the fixed point of the first floor foundation. This kind of green laser pointer has a keychain for easy carrying.
Open readings of the two-dimensional measurement shimmer target switch, the center of the laser beam spot on the two-dimensional measurement shimmer target, adjust the light on the target vernier, so that the spot center at the center of the X, Y, rope, and then align the center of the reticle, the first point cleared, set the reference point, after each point is relative to the first point of deviation, Xi, Yi, the value of each point measured is i X, Y coordinate values, ie the layer the spatial location of the reference point value. When the need for precision measurement, rotating hosts on the diameter measurement, in order to improve the accuracy of vertical measurements. Construction according to this measured value with the plane of the actinomycetes; acceptance according to the value of this test can determine the vertical and quality status of the building to meet the requirements. It is a very sweet and considerate design of china laser pointerfor the customer.
