How To Adjust The Sid-View Focus

For NTG500, NTG500H, NTG500P Fixed-Focus Borescope

For example:

• A. For a .22 caliber barrel, screw the mirror out to a position farther away from the camera and fix it with the lock ring. (Approximate distance: 5.56mm from camera, 2.78mm from mirror end).
• B. For a .30 caliber barrel, screw the mirror closer to the camera. (Approximate distance: 7.62mm from camera, 5.8mm from mirror end).
