Q:What is the construction of the laser level meter and the dry cell?

General No. 5 battery.

Q:BOSCH low level instrument to see the comment, the line out too thick. Are there any other good brands to recommend?. There are so many brands on Taobao that they look dazzling.

I'm using Black & Decker, and I feel fine.

Q:Which brand of laser marking instrument (level instrument) is of good quality?

Leica marking machine is the best in ChinaI feel the Leica laser shines brighter than the othersWhen a wide range of tile that put the apparatus on the Leica line closer to the machine (as opposed to other marking instrument)

Q:When the laser level is opened horizontally, it does not move on one line when it moves around. How can it be corrected?

Move the instrument around? If so, it is because of the uneven terrain, the height adjustment can be.If it's spinning around, that's the instrument itself. Need to be calibrated or repaired.

Q:The role of the bottom magnet of the laser level

Adsorbed onto the surface of an object

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:How can the laser level adjust the height of the horizontal line?

You can fix the level on the three stand and adjust the height of the horizontal line by adjusting the height of the three leg.Laser level meter operation mode: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 is based on the slope value of one meter as long as the actual tilt of the length of L is calculated by the following: the actual slope = the value of the division *L*, the number of deviationsIn 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.Level zero calibration method: the horizontal instrument is placed on the base of the stable and approximately horizontal plate (or machine tool guide rail). When the bubble is stable, the end is read at the 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.

Q:What's the use of an automatic laser level?

Paving tiles will be used to find horizontal and vertical lines

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
