Q:Laser level can see the horizontal line in the sunlight is that good
Green light, now a new red, green light level, the price is not high, easy to use, very good.
Q:Laser level sDB1, four threads are all broken, I do not know which welding!
Red is the power line VCC, black V1 V2 and OUT H are red, do not take the wrong line, other wrong never mind, is not corresponding to switch, can also be used, you can see the circuit board, marked above
Q:What brand of laser level is good? How much is the price?
A level instrument in which laser beams are used instead of manual readings. The laser beam emitted by the laser is introduced into the telescope cylinder to send a horizontal laser beam along the collimation axis. By means of the monochromatic nature and the coherence of laser, a piece of glass or a piece of metal with a certain shading pattern can be assembled in front of the telescope object lens, that is, the zone plate can cause diffraction interference. Through the telescope focusing, the focusing range zone plate, a bright and fine cross shaped or circular laser spot, thereby more accurate sighting target. If the photoelectric receiving target can be automatically tracked on the front and back level scales, leveling can be carried out. In the construction survey and assembly of large components, the laser level was used to establish the horizontal or horizontal lines in 1989.Digital level is the most advanced level, with a special bar level, through the instrument built-in digital imaging system, automatic level bar bar code readings, no manual reading is needed. This instrument can greatly reduce the labor intensity of Surveying and mapping work, avoid the subjective subjective reading error, and improve the measurement accuracy and efficiency
Q:Laser level, besides BOSCH, what other good brand?
DEWALT is acceptable
Q:Method for using laser infrared level instrument
Infrared level instrument, also known as throwing wire instrument, belongs to the basic line instrument, there is no difficulty, according to the instructions used
Q:When the laser level is opened horizontally, it does not move on one line when it moves around. How can it be corrected?
The laser level adjustment in the horizontal center position, must take the center point adjustment in the center position, the more accurate and better. Don't think that we didn't ring eccentric alarm at certain position in the center, in fact is not necessarily is the center, but at a distance shorter than not more than 10 meters outside the basic can be a one-time success. The largest error is not more than 3 mm. When the flat side of the distance is beyond the scope of the provisions of the level; if the adjustment center at this time is not accurate so you need to first level line type as the base line to end then extended or moving position and the direction of the words: it is certainly to the connection is not at the same level error is large, so the level of the line side must not!
Q:The role of the bottom magnet of the laser level
Specializing in the sale of precision measuring instruments - Wuxi Rongsheng
Q:I want to buy a laser level, I do not know is good or green, its principle is good, can see the horizontal line in the sun
Other colors are not easy to see during the day
Q:How can the laser level adjust the height of the horizontal line?
Seems to only be adjusted with a tripod, there is no other way
Q:What's the use of an automatic laser level?
A vertical line horizontal angle line, multi point used for interior decoration, outdoor light strong out of sight line
