    Tips: How to Maintain Surface Roughness Tester?

    • Cleanliness. Regularly clean the tester using a soft cloth or brush to remove any dust, debris, or contaminants that may affect the accuracy of the measurements. Ensure the measuring surfaces are free from dirt or oil.
    • Calibration. Perform regular calibration according to the manufacturer's instructions. This ensures accurate and consistent measurements. Use traceable calibration standards and adjust the tester if necessary.
    • Storage. Store the surface roughness tester in a clean and dry environment, away from extreme temperatures and humidity. Use the provided protective case or cover to prevent damage during storage.
    • Handling. Handle the tester with care, avoiding excessive force or impact that could damage its sensitive components.
    • Regular Inspection. Periodically inspect the tester for any signs of wear or damage, such as scratches, cracks, or loose parts.
