How to set up a digital level
How to set up the level? A level is an instrument for establishing a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points according to the leveling principle. The main components are telescope, tube level (or compensator), vertical axis, base, foot screw. According to the structure, it is divided into micro-tilt level, automatic leveling level, laser level and digital level (also known as electronic level). According to the accuracy, it can be divided into precision level and ordinary level. So how to set up the level? Zhuhai Tianchuang Instrument Co., Ltd. will explain in detail for you:
1) Choose a position that is easy to operate and easy to observe the measured target, elevation reference point, and reference line to install the level.
2) Open the tripod, step on the ground with three iron feet, and roughly level the frame head. The height of the upper plane of the frame head is too small or too low, which is not convenient for future operations. The appropriate height should be slightly lower. below the operator's jaw.
3) Take out the instrument, put it on the head L of the tripod, hold the instrument with one hand, and screw the central connecting bolt on the head of the stand into the bolt hole on the base plate of the level with the other hand to connect the level with the tripod .
4) Coarse leveling of the level: Adjust with three foot screws. The hammer crusher first rotates two foot screws (one to the left, one to the right, and the two rotation directions are opposite). Adjust the air bubble to the middle of the two foot screws, and then turn the other foot screw to adjust the air bubble to the center of the circular level. Rotate the telescope 90°. , 180. , observe whether the bubble in the circular level is still in the center position, if there is any deviation, adjust it again according to the above method until the telescope turns to any angle and the bubble in the circular level is still in the center position, indicating that the level has been roughly leveled (ie: preliminary leveling).
5) At this time, the bubble in the long level is not necessarily in the center, and can be adjusted by the fine-tuning knob of the long level. The degree of overlap of the two bubbles can be seen from the lens of the rock breaker. If they overlap completely, it means that the level has been leveled .
