Correct operation of the rebound tester 1. Put the ejector rod against the surface of the concrete, lightly press the instrument to loosen the button, when the pressure is released, the ejector rod is extended, and the hook is hooked with the hammer.
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 the impact rod is hit, the rebound of the hammer will move the pointer back to a certain position. The value line shows a certain value on the scale is the rebound value.
3. Make the movement of the instrument continue to bear against the concrete surface to take readings and record the rebound value. If the conditions are not conducive to reading, you can press the button, lock the movement, and move the instrument to another place to read.
4. Gradually depressurize the instrument so that the flick rod will protrude from the instrument until the next use.
