回弹仪常见问题及维修（Common problems and maintenance of resiliometer）

回弹仪常见问题及维修（Common problems and maintenance of resiliometer） A bomb attack in the test, the pointer stopped at the starting position without moving the slider: 1. pointer spring break, the spring in the elastic hammer struck the hanging elastic hammer, the pointer stopped at the starting position without moving the slider. Maintenance method: replace the spring piece. 2., the take-off position of the hammer is not qualified, causing the pointer block to stop at the starting position. Maintenance method: adjust the position of the nut of the back cover and make the position of the hammer reach 100 lines. 3. pointer pointer slider relative to the pointer shaft angle is too small, then the pointer in the process of elastic hammer impact friction force is too small, so that the pointer does not slide. Maintenance method: remove the pointer part, pull the appropriate large angle, within the prescribed scope. Rising position, not moving 1. pointer pointer slider relative to the pointer shaft angle smaller than the pointer in the process of elastic hammer impact friction force is relatively small, so that the pointer does not slide. Maintenance method: remove the pointer part, pull the appropriate large angle, within the prescribed scope. With the loose 2. pointer slider and the pointer shaft, then the friction force between the pointer and the pointer shaft is too small, can not make the spring normally on elastic hammer, it will shake to a fixed location. Maintenance method: remove the pointer, appropriate that the small reed angle in the specified range. The 3. indicator slider is rubbed against the shell or scale to increase the friction force during the sliding of the index and to wobble to a certain position. Maintenance method: use small file, appropriate file, pointer, slider, flat or two shoulder, until friction elimination. Button not available 1. the buffer spring is jammed by the button and can not move. Maintenance method: open the back cover, remove the buffer
