Illumination System (Continued)

Borescope Body

The body is the hand-piece of the borescope. Focus, Zoom, Rotary Scan and Swing

Prism control knobs are conveniently located on the body.

Shaft (or Barrel)

The shaft, or barrel, is the working length of the borescope and carries the optical

train into equipment to be inspected. The shaft’s unique triple tube design provides

special protection of the optical train and enhances the durability of the scope.

Distal Section

The distal section houses the termination point of the illumination fiber-optic bundle and

the lens set that focuses images into the optical train. These components are assembled

in a precise orientation to provide the highest possible imaging performance, along with

the desired direction and field-of-view.

Setup consists only of focusing the eyepiece to your eye, plugging a light guide into the post

and available light source, and making a few checks to ensure the borescope is operating

properly.

Focus the Eyepiece: Remove protective lens caps and, if desired and available, attach the

rubber eyecup. Focus the eyepiece for your eye by rotating the focus knob while looking into

the eyepiece. The viewing tip should be pointed at an object with sharply defined edges. Typed

Plug into a Light Source:ConnecttheexitendofanACMIlightguidetotherigidscopepost

and insert the other end into the light guide socket of an Everest VIT or other compatible light

source. Turn the light source on, wait about 30 seconds for the lamp to reach peak intensity,

and check to ensure that a bright light is projected from the tip of the borescope. The scope

is now ready to use.

Check Operation: Look through the eyepiece to ensure the scope is providing a sharp, clear

image. Clean the eyepiece and distal cover glass if dirty. Check the operation of all equipped

features, such as focus, rotary scan, zoom and swing prism. If performance of any of these fea-

tures is degraded, return the scope to the Service Center for evaluation and repair. Continued

use of a damaged scope could cause further damage.
