Level compensator cross put the instrument to correct errors in the correction stage water level calibration maintenance, adjustment circular bubble centered and leveled Level instrument precision instrument, then tilt the instrument (even if the instrument left high right low or right high left in the instrument compensation range low), then if the reticle crosshairs above or below the target crosshairs automatically 安平光 school Level, then prove that the instrument has a cross error can be corrected by adjusting the water level compensation on the side of the left and right sides of the two small screws until adjusted to within the permissible range is a measure of ground water level point level measurement principle based on the height difference between the instruments. 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 used the height measurements, the following will explain how to use the Automatic Level elevation measurements performed. When using the Automatic Level observation, when circular level is centered the instrument is flat, without further manual adjustments can be read by reading the time was eye level. It simplifies operating procedures, improve operating speed, to reduce measurement error caused by changes in ambient conditions. Automatic Level compensator kind compensation, in accordance with the damping can be divided into air damper compensator and reluctance compensator. Wherein the magnetic damping compensator can be divided according to the different desktops configured with magnetic damping compensator, cross-type magnetic damping compensator. Level calibration maintenance, level, provided by the Branch of the Instrument Instrument Co., Ltd. Qingdao Branch. Qingdao Branch of the Instrument Co., Ltd.
