Move the tester along the cable or inspect connector end faces to detect dirty or damaged areas. Switch the device off after testing to preserve battery life.

Recommendations

Use eye protection and avoid direct eye exposure to the visible light source. Clean connector end faces before testing for more accurate results and use proper adapters when necessary to match different connector types.
