Level zero calibration, adjustment method:
Place the level on a flat plate (or machine tool guide) with a stable and roughly horizontal foundation. After the bubbles stabilize, read at one end, such as the left end, and set it to zero. Adjust the level by 180 degrees and still place it in the original position of the flat plate. Maintain the machine tool, scrape and grind the machine tool guide rail, repair the flat plate, Chongqing Square Square Sales Company, Chongqing Deflection Instrument Sales Company, Chongqing Level Sales Company, Sichuan Cast Iron Flat Platform Sales Company, Chongqing Cast Iron Flat Platform Sales Company, Guangxi Cast Iron Flat Platform Sales Company, Guizhou Cast Iron Flat Platform Sales Company, Yunnan Cast Iron Flat Platform Sales Company, After the bubble stabilizes, the Shaanxi Cast Iron Flat Platform Sales Company and Hubei Cast Iron Flat Platform Sales Company still read A grid at the original end (left end), resulting in a level zero error of two-thirds of A grid. If the zero position error exceeds the allowable range, the zero position adjustment mechanism of the level needs to be adjusted (adjust the screw or nut to reduce the zero position error to within the allowable value. For screws that are not regulated for adjustment, the nut cannot be unscrewed at will. Before adjustment, the working surface of the level and the flat plate must be wiped clean. After adjustment, the screw or nut and other components must be tightened)
Precautions:
1. Before using the level gauge, wash the anti rust oil on the working surface with non corrosive gasoline and wipe it clean with degreased cotton yarn before use.
2. Temperature changes can cause measurement errors and must be isolated from heat and air sources during use.
3. When measuring, it is necessary to wait for the bubbles to completely rest before reading.
4. After using the level, the working surface must be wiped clean and coated with anhydrous and acid free rust proof oil, covered with moisture-proof paper, and placed in a clean and dry place for storage.
5. Under the premise of correct use and storage, the level gauge shall be repaired, returned, or replaced for free within six months from the date of production due to manufacturing defects or malfunctions. However, the products required for entering and exiting this item must have a complete structure and undamaged appearance.
