The level (English: Level) is a instrument with a height difference between two points between the ground to determine the horizontal sight.The principle is to measure the height difference between the ground points according to the principle of the level.The main components are telescope, tube standard (or compensator), vertical axis, base position, and foot spiral.According to the structure, it is divided into micro -level levels, automatic security levels, laser levels, and digital level meters (also known as electronic standards).Classified by accuracy is divided into precision levels and ordinary levels.
What are the axes of the level instrument
First of all, the main axis of the standard: 1. Visited axis CC2, Tube -level device axis LL3, Circle Hermiter shaft LL4, vertical axis VV
Active correction method
1. The test and correction of the round -standard air bubble shaft: First of all, the spiral spiral operation of the foot is performed to allow the round -level air bubbles to be located in the center of the instrument, then rotate the level instrument by 180 degrees, and then check whether the position of the round -level air bubbles will change.If the position changes, the level instrument needs to be corrected.The correction method of round -level air bubbles first performs the rotation operation of the foot spiral, so that the round -level air bubbles are located in the center of the distance generated by the offset, and then use the correction needle to adjust the correction screw below the circular level to the correct position. Create the spiral spiralThere are three numbers, and repeated operations are continuously carried out. When the round -level bubbles no longer offset, the correction work is completed.

How to use the level
1. The resettlement instrument opens the triangle to make it height near the chest, the head of the shelf is roughly level, and step on the toes into the soil, and then use the connection to spiral to connect the instrument on the tripod.2. Understand the name of the instrument and the role of the components of the instrument and be familiar with the use method.At the same time, familiar with the schedules of the standard ruler.3. Roll up the two feet spirals to rotate the two feet, so that the round -level bubbles move to the middle, and then turn the spiral of the other foot to move the bubble to the center position.4. Aiming at the scoring spiral of the mirror mirror to make the cross wire clear; turn the instrument, aim at the level ruler with the quasi -star and the door, tighten the braking spiral (the hand -sensing spiral resistance), rotate the micro -movement spiralAt the point.When the imaging is not clear, rotate the spiral of the light to eliminate the visual difference and make the target clear.
