Q:Laser level instrument broken line, how to repair?
This kind of instrument needs to be corrected on a special station. Even the general circuit problems need to be corrected after the maintenance, not to mention the laser tube is burned and needs to be replaced.
Q:The role of the bottom magnet of the laser level
Adsorption onto the surface of an object for ease of use
Q:What is the construction of the laser level meter and the dry cell?
We use the Hilti 5 batteries, seems to have a kind of 9V square battery
Q:What's the difference between 2 wire, 3 wire, 5 wire laser infrared level?
2 lines, 3 lines, 5 lines of laser infrared level is called a popular user name, the actual should be: 1 vertical 1 Ping (2 lines), 2 vertical 1 Ping (3 lines), 4 vertical 1 Ping (5 lines), 4 vertical 4 Ping (8 lines)2 lines: a horizontal line, a vertical line. Can measure the horizontal and the vertical line3 lines: a horizontal line, two vertical lines. Can measure the level and plumb line, one direction at right angles to the measured ground or zenith, vertical space point.5 lines: a horizontal line, four vertical lines. Can measure the level and plumb line, four directions at right angles to the measured ground or zenith, vertical space point.8 lines: one week horizontal line, four vertical lines. Can measure the level and plumb line, four directions at right angles to the measured ground or zenith, vertical space point.The difference is that the number of lines that can be emitted is different from the laser line, and the range of use is also different.
Q:What's the use of an automatic laser level?
It's for leveling
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 are the common problems with infrared laser levels? How should I solve it?
Product features:1. Launch a horizontal line2. Emit four vertical lines and cross each other at the zenith3. Launching a site for plumb points4 、 automatic Anping and over range automatic alarm function5 、 equipped with magnetic damping compensation system6, with the receiver, the effective distance of 30 meters
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:How to use laser level?
When measuring, the working surface of the level instrument is close to the tested surface, and the reading can be carried out until the bubble is completely stationary.The graduation of the level meter is based on the slope value of one meter long, and the actual tilt, if measured at L, can be calculated by the lower type:Actual slope value = division value *L* deviation grid numberIn order to avoid the measurement error caused by the zero position of the level instrument, the zero level of the level instrument must be checked or adjusted before use.Zero calibration and adjustment method of level instrument:Place the level gauge on a flat, substantially flat plate (or machine tool guide), until the bubble is stable, at one end, such as the left end, and zero. Then turn the level of 180 degrees, still placed in the original position of the plate, to be stable after the bubble, still in the original one (left) readings A, the level of zero error is two points A grid. If the zero error exceeds the permissible range, then adjust the level zero adjusting mechanism (adjustment screw or nut, the error is reduced to zero within the allowable value. The nut shall not be turned freely for the screws which are not specified. Adjust the level of working surface and the plate must be torn wipe clean. The adjusting screw or nut must be tight
Q:What happens when the vertical level of laser level is tilted?
Take back to the factory maintenance, their own bad operation
