Htc Digital Rebound Hammer

How to Use a Digital Rebound Hammer: 1. Prepare the Concrete Surface: Ensure the surface is clean, smooth, and dry. Remove dust, debris, or coatings that could affect readings. 2. Power On and Set Parameters: Turn on the digital hammer, select measurement mode (if applicable), and check battery level. Some models allow you to set units or store data. 3. Position the Hammer: Hold the hammer perpendicular to the concrete surface. Keep it steady for accurate measurement. 4. Perform the Test: Press the plunger until the internal spring releases, striking the concrete. The digital display will automatically show the rebound value. 5. Take Multiple Readings: Conduct 8–10 tests in the same area for reliability. The hammer often calculates the average value automatically. 6. Estimate Compressive Strength 7. Record and Store Data
