Firstly aimed at leveling rod eyepiece light. The telescope towards a bright background (such as the sky or white bright objects) and turn the telescope eyepiece focusing screws so the telescope crosshairs within the image is very clear. Then release the brake screw, turn the telescope Level, with crude telescope aiming sight leveling rod, then tighten clamp screws. Observation target from the telescope, the telescope lens focusing screw rotation, so that the standard of foot clear image. Then rotate the horizontal tangent screw to make the reticle foot vertical wire located on the side of the center line level or grade rod. Observer your eye moves up and down, whether observed level ruler image with crosshairs relative movement. If Optical Level principle, then there is the disparity, this time should be carefully adjusted the eyepiece and objective lens to light spiral, until the level ruler image with crosshairs no relative movement until the water level is measured according to the standard ground point elevation difference between the measurement principle of the instrument. Compensator under gravity to move relative to the telescope, thereby obtaining the scale reading at eye level quickly. This instrument representing leaning Level high efficiency, accuracy and stability. Level measurement can be achieved in three main areas. They are the height measurement, distance measurement, direction angle measurement. And we usually measure the water level height is commonly used to use, the following will explain how to use the Automatic Level elevation measurements performed. Level, automatic Anping compensator lens according to the structure can be divided into activities, events crosshairs and other hanging prisms. Compensation device has a "put" Level measurement correction, when the telescope line of sight is slightly tilted, the compensation component will produce swing, for the "pendulum" swings can be stabilized as soon as possible, be fitted with an air damper or magnetic damper. This instrument representing leaning Level high efficiency, accuracy and stability, especially in working more significant in windy and temperature changes in the region. _ Level Level DSZ2_ Branch of the Instrument choice is provided by the Qingdao Branch of the Instrument Co., Ltd.
