YHJ-50 （ A ) type Laser Slope Gauge Instruction Manual

Uses

YHJ-50 （ A ) The laser slope gauge is primarily used for aiming, positioning, and alignment along the working face in mining operations, as well as during installation and other related engineering tasks. It is specifically designed for coal mine coal-mining workfaces. The “Three-Flat-One-Consistent” standard has been met, and this new type of surveying product is used to replace traditional string lines in operations such as setting out center and waistlines for drilling and support at the tunneling face, positioning and installation of mechanical and electrical transportation equipment, and string-line layout for civil engineering and road construction. It boasts advantages such as compact size, light weight, portability, ease of operation, high operational efficiency, and minimal interference with other work processes. 。

to put YHJ-50 （ A ) The two external hooks of the laser slope gauge are hooked onto the provided center. ( waist ) On the device, turn on the power, and the laser line will project. Adjust the angle using the pointer, then proceed with construction according to the laser line.

IV. Precautions

YHJ-50 （ A ) The laser slope gauge is an optomechatronic measuring instrument; therefore, the following precautions should be observed during use. : Avoid any hard impacts or crushing of the instrument; handle it gently to prevent damage to the light-emitting tube and deformation of its external dimensions. During use, absolutely prohibit exposure to water or immersion. Use 1 If the instrument exhibits any appearance deformation after one year of use, it must be returned to the factory for verification and calibration to ensure it meets the required performance standards.

Turn off the power switch promptly after use.
