The quality inspection of green laser pointer contains three processed

The entire building each measuring point selection: the reference point should be not less than two points, the plane shape of the building complex should be selected according to their shape. JZC-G, 3.5 in the use of the building deformation observation instrument, it can be measured back to the vertical quasi-measurement standard deviation is small, its repeatability data for building long-term deformation monitoring. Important buildings such as the reservoir dam, a large train station, high floor, and important buildings should be long-term observation of the deformation, especially in uneven settlement areas or even should be done in the construction in deformation monitoring in order to find defects as early as possible to take measures to bring an early resolution of. For this kind of china laser pointer, a piece of AAA battery is enough to switch on the laser pointer.
Along the dam dam, dam dam deformation monitoring of layout JZC-G instruments, a number of monitoring points located along its senior Factors due to changes in the reservoir water level, seasonal temperature changes, and uneven settlement of the dam foundation and cement shrinkage deformation, etc., dam of the dam will be a certain degree of deformation. JZC-G instrument is a high precision pointing to the zenith of the baseline, the relative position between the observed and recorded each monitoring point and baseline for the dam deformation analysis, in order to determine the dam the deformation is in the design of the allowable range. Building uneven settlement observations after the completion of the project, many of the reference point in the construction and monitoring points for each floor will follow the removal. The AAA battery used by china laser pointer is commonly seen in the store and supermarket so that the customer can buy AAA battery easily.
Building uneven settlement observation best position in a corner of the elevator shaft, set up observation points, regularly monitored. Can also use the Dalian Economic and Technological Development Zone, the elevator guide 5 Lats 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 rail vertical degree of change for regular monitoring. A large number of our buildings were built in the major rivers in alluvial plains. These high-rise buildings, should pay attention to the uneven settlement of the monitoring in order to take timely measures to ensure safety and extend the service life of the building. It is the quality inspection ofchina laser pointer.
The instrument self-test and self-inspection and self-calibration instruments from the school for the vertical accuracy of the instrument, that is, a single laser beam with the theoretical vertical angle of the self-test and self-calibration. 3.6.1 self-test self-test is used for diameter measurement, assumed Ranging L (mm), when the instrument azimuth 0 °, the significant light on the target number of two-dimensional micrometer, Y (can also be cleared simultaneously ); rotating reticle laser beam ring Shan on time, the reading on the X and Y coordinates of X1 (mm) (mm) instrument azimuth 180 °, re-adjust the reticle with the laser beam ring Shan alignment, both X and Y coordinates on the readings for the X2 (mm) and Y2 (mm). After accomplishment of producing china laser pointer, the quality inspection of the laser pointer should be timely and strictly implemented by the specific quality inspector.
First calculate the mean of X = 1 1 (X 1 + X 2); Y = (Y1 + Y2) 2 2 single beam vertical accuracy of the laser beam is calculated as follows:? = 3600 × arctg (X? X 1) 2 + (Y? Y1) 2 (〃) L (mm) (mm) (mm) (Screen) where: X1 and Y1 for the diameter measurement of a measured value of X and Y as diametrical two measured The mean value of L for the measurement of the optical path? single beam of the laser beam perpendicular to the degree of accuracy 3.6.2 Since the school-based instruments can be self-correcting. Bench, mirror I mirror II, two-dimensional measurement the shimmer target, magnetic table seat according to Figure 6 in the experimental stage (Figure 6), through the double-wedge adjustment can be a single laser beam of the vertical degree of accuracy is raised 2 〃 within. The quality inspection of green laser pointer contains three processed.
