Coarse level that is roughly flat coarse leveling instruments. Level three feet by rotating the base of the spiral bubble to the center of the circular level Level purposes, the vertical axis of the instrument substantially vertically, so that the substantially horizontal axis collimation telescope. In the process of leveling Suzhou Level dsz2, foot spiral direction of rotation law and the direction of movement of the circular level is: with his left foot rotary screw water level, the bubble moving direction and consistent left thumb (left thumb method) the direction of movement; with the right hand Turn the leveling screw, then the direction of movement and the right index finger of bubbles moving in the same direction. The telescope pan 180 °, check the circular level is still centered, or re leveling DSZ2 Product parameters: measuring the standard deviation per km roundtrip DSZ2: ± 1.5mm (general scale) ± 1.0mm (indium steel ruler) 32 × magnification Minimum sight distance 1.6m compensation in the range of ± 14 'compensation Anping accuracy ≤ ± 0.3 "Instrument Weight 2.5kg Branch of the Instrument (Figure), Level function, level provided by the Qingdao Branch of the Instrument Co., Ltd." mapping equipment, analytical instruments , testing equipment, flow meters, optical instruments, temperature instruments, "Preferred Instrument Co., Ltd.
