How to Use the Level

- Apr 26, 2016 -

1. The scale value of the level is expressed by the angle (seconds) or the slope. Its meaning is expressed by the angle at which the bubble is shifted by one grid, or by the height of the bubble offset by one grid of the working surface.
2, because the angle of use of the level is very small, so tg, such as tg4 4 radians = 0.02mm / 1000mm, the level of the working surface of the level is close to the surface to be measured, after the bubble is stable, can be read, if you need to measure the actual length of L The tilt value can be calculated by the following formula.
