In fact, it is a type of measuring instrument made by installing and fixing a laser device on the telescope tube of an ordinary level. Project a horizontal and plumb laser line, and finally achieve the purpose of measurement.
Function:
1. The laser level meter can measure whether the plane is uneven or hanging paintings, etc.
2. Output the vertical plane and horizontal point of the laser.
3. There are horizontal beads on the laser level, which can measure whether the horizontal plane is level.
4. There are LED lamp beads on the laser level meter, you can see the horizontal beads clearly even at night.
5. The laser level meter can add a magnet to attract more practical and convenient functions.
Principle:
The principle of the wire throwing instrument is mainly gravity induction, and the main It is used to measure whether the object is up and down parallel to the level Face, whether the left and right are tilted.
The blisters are used to measure the left and right tilt, when you use just put the level on the surface of the object, turn the knob to center the bubble, and it's ready to use.
The Base Knowledge Of Laser Tools
The laser level is generally used in mechanical manufacturing for sheet metal processing and for scribing and positioning steel plates. Of course, it can also be used on various industrial production equipment to assist and position markings. Of course, it can also be used for equipment installation and positioning in the construction industry. It can be seen that the usage rate of this laser level in our daily life is really all aspects. The general people may not know how to use the laser level. The following editor will give you a brief introduction to the use of this laser level!
1: First turn on the switch, (the switch is on the side) whether the laser level meter is three-wire or five-wire. There should be an automatic correction system on the level meter (there is 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 level meter close to the surface to be measured, and take the reading after the bubble is completely still.
3: The graduation value of the level meter is the inclination value with one meter as the base length. If you need to measure the actual inclination with a length of L, you can calculate it by the following formula:
Actual tilt value=Graduation value*L*Deviation grid number
4: In order to avoid measurement errors caused by the inaccuracy of the zero position of the level meter, the zero position of the level meter must be calibrated or adjusted before use.
Level meter zero calibration, adjustment method:
Put the level meter on a stable foundation, roughly horizontal plate (or machine bed rail), after the bubble stabilizes, read at one end, such as the left end, and set it to zero. Turn the level meter 180 degrees again, and place it on the original position of the plate. After the bubble stabilizes, the level A is still reading at the original end (left end), and the zero position error of the level meter is A-half of the level.
If the zero error exceeds the allowable range, you need to adjust the level meter zero adjustment mechanism (adjust the screw or nut to reduce the zero error to within the allowable value. For non-specified adjustment screws, the nut should not be screwed at will. The level meter works before adjustment The surface and the plate must be peeled and wiped clean. The screws or nuts must be tightened after adjustment).
