Maintenance Information
Regularly clean the goniometer and headform surfaces to remove dust and debris.
Inspect and replace drive belts and bearings periodically to ensure smooth operation.
Verify angular encoder calibration at least once every 6 months using NIST-traceable instruments.
Store the machine in a dry environment to prevent corrosion of aluminum and steel components.
Follow standard electrical safety protocols when connecting power supply.
FAQ
1. What is a Standard Helmet Visual Field Tester?
This device is used to evaluate the wearer’s field of vision when wearing a helmet, ensuring that the helmet design does not obstruct peripheral or direct sight and meets safety standards.
2. How does the visual field test work?
The helmet is mounted on a headform or worn by a test subject, and visual field measurement tools or optical sensors map the visible area in all directions. Obstructions caused by the helmet are quantified.
3. What types of helmets can be tested?
It can test industrial safety helmets, construction helmets, bicycle helmets, motorcycle helmets, and other protective headgear that requires adequate visual clearance.
4. What parameters are measured during testing?
The tester measures horizontal and vertical field of view, blind spots, obstruction angles, and visibility limitations. Some systems provide digital mapping and visual field diagrams.
5. Why is helmet visual field testing important?
Testing ensures that helmets do not compromise wearer safety by restricting vision, allowing users to detect hazards and operate safely. Compliance with standards such as EN 397. ANSI Z89.1. or ISO is verified.
