Su Yiguang Level: 1. Level is a precision optical instruments Level instruments, correct and reasonable use and care of the instrument precision and life have a great effect; 2. Avoid direct sunlight, do not permit just disassemble the instrument; 3. Each spinner should gently turn, do not use excessive force. Lens, the optical sheet contacts allowed hand; 4. Equipment failure, is familiar with the instrument structure or repair shop repair 5. After each use, clean water level instrument, keep dry. 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" domestic water level, when the telescope line of sight is slightly tilted, the compensation element 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. Su Light Level (automatic level) is defined within a certain range of the vertical axis tilt when compensating automatically get eye level leveler leveling staff readings. When using an automated Anping compensation instead of tubular vial, when the instrument is leaning compensation by gravity with respect to the telescope tube to move, so that the correct reading at eye level on the scale of compensation still falls after the adoption of the horizontal cross-hairs. 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, in order to reduce the external conditions of observation errors caused by changes in water level manufacturers, level, provided by the Branch of the Instrument Instrument Co., Ltd. Qingdao Branch. Qingdao Branch of the Instrument Co., Ltd. (www.qdjk17.com) strong, credible, in Qingdao, Shandong analytical instruments industry has accumulated a large number of loyal customers.
