3. Орнотуу

Before first use, ensure all components are present and in good condition. The device is pre-calibrated, but regular checks with the included grinding stone are recommended to maintain accuracy.

Сыноочуну даярдоо:

1. Remove any protective adhesive tape from the button area.
2. Press the impact plunger gently to ensure it moves freely and the button pops out. Slowly release the plunger.
3. If the concrete surface is rough or uneven, use the included grinding stone to smooth a small area for testing.

4. Иштөө нускамалары

Follow these steps for accurate concrete strength testing:

1. Prepare the Plunger: Tear off the adhesive tape and press the impact plunger to make the button pop out. Slowly release the impact plunger.
2. Position the Tester: Place the rebound hammer perpendicular to the concrete surface to be tested.
3. Кысым колдонуу: Slowly and evenly apply pressure to the tester until the plunger impacts the surface and a "bang" sound is heard. Keep the button pressed at this point.
4. Read Rebound Value: After the rebound, release the button once the hammer leaves the concrete surface. Read and record the rebound value indicated on the scale.
5. Кайра сыноо: Repeat the above steps multiple times (e.g., 9-12 times) in different spots within the test area to obtain an average rebound value.

Using the Correction Coefficient Table:

For more accurate results, especially when dealing with carbonated concrete, refer to the carbonation depth correction table provided in the manual or on the device label. The unit labeled on the instrument is MPa (N/mm²), where 1 MPa = 145 psi.

5. Техникалык тейлөө

Proper maintenance ensures the longevity and accuracy of your rebound tester.

• Тазалоо: After each use, wipe the tester clean with a soft, dry cloth. Ensure no concrete dust or debris remains on the plunger or scale.
• Сактагыч: Store the device in its protective case in a dry, cool environment, away from direct sunlight and extreme temperatures.
• Ташты майдалоо: Use the included grinding stone to periodically clean and smooth the plunger tip to maintain consistent impact.
• Калибрлөө текшерүү: Periodically check the calibration against a known standard or reference block to ensure continued accuracy.

6. Кыйынчылыктарды

If you encounter issues with your ZC3-A Concrete Rebound Tester, consider the following:

• Туура эмес окуулар: Ensure the testing surface is smooth and clean. Verify the tester is held perpendicular to the surface. Check if the plunger tip is clean and not worn.
• Plunger Not Rebounding: Check for any obstructions or damage to the internal mechanism. Ensure the button is pressed correctly after impact.
• Button Not Popping Out: Ensure no debris is blocking the button mechanism. Gently press and release the plunger to free it.
