The digital rebound hammer is designed and manufactured according to the industrial standard of the People's Republic of China, "Technical Regulations for Testing Concrete Compressive Strength by Rebound Method" JGJ/T23-2001. It is mainly used for non-destructive testing of ordinary concrete compressive strength in structural engineering. main feature: 1. One main machine can be equipped with multiple mechanical heads to ensure the smooth operation of the test. Digital rebound hammer operation interface 2, full Chinese large screen LCD display, easy to operate 3, the digital histogram double display rebound value, more intuitive 4, connected to the PC, can automatically generate reports Instructions 1. Hold the impact rod against the surface of the concrete, gently press the instrument to release the button, and when the pressure is relaxed, the impact rod extends and the hook is hooked. 2. Make the axis of the instrument always perpendicular to the surface of the concrete and apply pressure slowly and evenly. After the hammer is unhooked and impacted, the value of the pointer will be changed when the hammer rebounds to move the pointer backward to a certain position. The score line shows a certain value on the scale as the rebound value. 3. Keep the instrument movement against the concrete surface reading and record the rebound value. If the conditions are not conducive to reading, press the button to lock the movement and move the instrument to its reading. 4. Gradually decompress the instrument so that the impact bar protrudes from the instrument and is used next time. Conventional maintenance method 1. After the hook is unhooked, the movement is taken out, and then the impact rod (removing the buffer spring inside) and the triple piece (the hammer, the spring tension spring and the spring seat) are removed; 2. Wash the parts of the movement with gasoline, especially the center guide, the inner hole of the hammer and the impact rod and the impact surface. After cleaning, apply a layer of watch oil or sewing machine oil to the center guide rod. Do not apply oil to other parts. 3. Clean the inner wall of the casing, remove the scale, and check that the pointer friction force should be between 0.5-0.8N; 4. Do not rotate the zero adjustment screw that has been positioned and fastened on the tail cover; 5. Do not make or replace parts; 6. After maintenance, the test should be carried out according to the requirements, and the rate should be 80±2.
