Level of use include: Level placement, coarse level, aiming, fine flat, reading five steps. For automatic levelizer, the fine level of step can be omitted. Specific steps are as follows: Place the instrument placement is installed retractable tripod and placed between two observation points. First, open the tripod and medium height, with a visual estimation so stand tripod head is substantially horizontal and check whether the firm Electronic Level, and then open the instrument case with a screw connection to connect to the standard instrument tripod. Correction compensator zero calibration of the instrument placed on the stage water level, and to adjust the circular bubble centered leveling instrument domestic water level, if the compensator compensation range is 30 ", but when the error is 10", the compensator can not work, then prove the need for the compensator zero calibration, the compensator just below a row of four screws, the middle two letters paint immobile water level precision, the two screws on both sides can be adjusted to compensate the zero bits. DSZ2 can be used for three or four countries, such as the standard observation, to meet a variety of engineering and construction standards of measurement requirements. The product provides automatic compensation function, can greatly improve the operating efficiency and avoid errors. DSZ2 + FS1 can be used in a country, the second leveling and settlement of precision measuring deformation. Features: compensator check button sealing against dust, compact, easy to operate structure, beautiful appearance can be equipped with micrometer level, can be used for the national secondary settlement observation precision leveling and excellent temperature compensation performance level Level | Jinke instruments ( Certified) | Level by Instrument Co., Ltd.
