Flat or rough rough rough flat leveling instruments. Level three feet by rotating the base of the screw so that the circular level bubble is centered, the instrument of the vertical axis substantially vertically, so that a substantially horizontal axis collimation telescope. In the leveling process, the direction of rotation of the foot spiral circular level and direction of movement of the law is: with the left foot rotating spiral, the bubble moving direction and consistent left thumb (left thumb method) the direction of movement; with his right foot rotating spiral Level accuracy, the moving direction of the bubble movement in the same direction and the right index finger. The telescope pan 180 °, check the circular level is still centered, or re-use automatic leveling levelizer main function is automatic leveling levelizer aimed at measuring height or elevation of a point between the two points . AT-G series is equipped with automatic levelizer horizontal circle, can be used for angle measurement. AT-G series automatic levelizer can be used to measure the horizon, it is the use of the instrument line of sight with reticle scale wires with a ruler (eg leveling rod or line of sight ruler) to measure the distance. Targeting (1) focusing eyepiece: Loosen the brake screw, turn the telescope bright background (eg: Sky) electronic level, turn the eyepiece light spiral to make the reticle clear imaging (2) The initial aim: through the top of the telescope tube optical sight aiming ruler Level, tighten screw brake. (3) focusing lens: Turn the focusing knob, making clear image of the ruler. (4) the precise aim: Turn the micro handwheel, make ruler imaging center in the field of view.
