Durable, Efficient, and ConvenientConstructed from ABS plastic and stainless steel, the tester is lightweight yet robust. With approximately 20 hours of operating time per charge and a quick 4-hour recharge, it minimizes downtime. Auto-shutdown further preserves battery life, while a sturdy carrying case enhances portability and protection.
FAQs of Surface Roughness Tester:
Q: How does the Surface Roughness Tester measure surface roughness?
A: The tester utilizes a diamond-tipped piezoelectric stylus that traverses the sample surface at a speed of 1 mm/s. It detects variations in surface profile, calculates roughness parameters such as Ra and Rz, and displays the results on a large backlit LCD.
Q: What materials and applications is this tester suitable for?
A: This instrument is suitable for inspecting metals, plastics, glass, and ceramics. It is commonly used in quality control, manufacturing, and laboratory environments to evaluate and document surface finishes according to ISO, DIN, ANSI, and JIS standards.
Q: When should I perform calibration on the tester?
A: Calibration is recommended before initial use, after significant changes in ambient conditions (like temperature shifts), or after extended storage. The included standard specimen makes it easy to perform calibration and maintain measurement accuracy.
Q: Where is the data stored and how can it be exported?
A: Measurement results are stored internally, with a capacity of up to 100 records. Data can be exported via USB to a computer in TXT or CSV format, facilitating easy analysis and report generation.
Q: What is the process for changing display units or language?
A: You can select between m and inch or switch menu language (English/Chinese) directly via the user interface on the LCD display, allowing for flexible operation suited to different user preferences and regional requirements.
Q: How does the auto shutdown feature benefit the user?
A: Auto shutdown conserves battery life by powering off the device after periods of inactivity, helping to extend operational time and reduce the need for frequent recharging.
Q: What safety or protective measures come with the tester?
A: A sturdy carrying case is included for transport and storage, protecting the device from physical damage. However, the tester is not waterproof, so it should be kept away from moisture during use and storage.
