How to use the laser level and its function
The laser level is an intelligent display device. The function of the laser level is that it can be installed on a moving object, collect the signal of the horizon, display the horizon in a large field of view, and display the movement posture of the object in real time. If the laser level is used on an airplane, it is of great significance to prevent spatial orientation disorders; in addition, in medical testing, using manual signals to adjust the position of the laser scanning line can perform certain pathological tests on the human brain, and it is also used in handicrafts. It is also widely used in construction and decoration fields. It is widely used in detection and measurement. Today, I will talk about the usage and functions of the laser level.
How to use the laser level
1. First turn on the switch, (the switch is on the side) whether the laser level is three-wire or five-wire. There should be an automatic correction system on the level (there is a water drop correction on it, and the water drop is in the circle.) If it is not level, it will automatically make a sound, and there will be no sound after it is level.
2. When measuring, make the working surface of the spirit level close to the surface to be measured, and take a reading after the bubbles are completely still.
3. The graduation value of the spirit level is the inclination value based on one meter. If you need to measure the actual inclination with a length of L, you can use the following formula to calculate: Actual inclination value = graduation value * L * deviation grid number
4. In order to avoid measurement errors caused by the inaccurate zero position of the level meter, the zero position of the level meter must be calibrated or adjusted before use.
Calibration of the zero position of the spirit level, the adjustment method:
Put the spirit level on a flat plate (or machine tool guide rail) with a solid foundation, and after the bubbles are stable, take a reading at one end such as the left end, and set it to zero. Then turn the level meter 180 degrees, and still put it on the original position of the plate. After the bubble is stabilized, still read the A grid at the original end (left end), and the zero position error of the level meter is 1/2 of the A grid.
If the zero error exceeds the allowable range, the level meter zero adjustment mechanism (adjustment screw or nut) needs to be adjusted to reduce the zero error to within the allowable value. For non-regulated adjustment screws, the nut must not be twisted at will. Before adjustment, the level meter works The surface and the plate must be wiped clean. After adjustment, the screws or nuts must be tightened).
