Level Operation points: two points in between is unknown, laid out a tripod, remove the water level mounted on a tripod base with three leveling screws from the instrument case, the circular bubble is centered, followed by leveling vial. Level system handwheel is leveling Level, within a horizontal triangular prism mirror reflection, coinciding level, it is the flat water. The telescope at the unknown point (1) foot tower, again leveling tube level is coincident readings readout foot tower (rear view), the telescope is rotated to the unknown point (2) foot tower, the regulator leveler Level calibration service, read out foot tower readings (front), credited to the record book. The formula: Two dots height = rear view - front view. Level aimed at (1) focusing eyepiece: Loosen the brake screw, turn the telescope bright background (eg: Sky), turn the eyepiece light spiral, make the reticle clear imaging (2) Initial sighting: through the top tube of the telescope optics aiming sight gauge, tighten the clamp screws. (3) The objective Focus: focusing hand wheel is rotated, so that the scale of the image clear. (4) precision targeting: Turn tangent screw, so the scale imaging center of the field. Su Light Level (automatic level) is defined within a certain range of the vertical axis tilt Level low sales, while compensating automatically get eye level leveler leveling staff readings. After the time is replaced by automatic Anping Level compensator tubular spirit level precision instrument, when the instrument is leaning compensation by gravity with respect to the telescope tube to move, so that the correct reading on the scale at eye level through the compensation level still falls crosshairs on. When observing the use of such water level, when the 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 the water level measurement error caused by changes in ambient conditions _ low sales Branch of the Instrument (certified) _ Level provided by the Qingdao Branch of the Instrument Co., Ltd. Qingdao Branch of the Instrument Co., Ltd. (www.qdjk17.com) is in Qingdao, Shandong analysis instruments leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Branch of the Instrument in leadership with the staff warmly welcome all inquiries negotiations to create the Branch of the Instrument better future.
