Inspecting Connectors

Adjusting Diopter

Prior to inspecting fiber optic connectors, you need to perform a diopter

adjustment to provide proper viewing of the display for your vision. This is

accomplished by observing the display with no fiber in the inspection port.

Note: This adjustment needs to be performed once unless your vision

changes over time.

Turn on the VS 300 inspection scope.

Slowly turn the eyepiece clockwise/counterclockwise until edges of the

display becomes clear, sharp lines and pixels become visible.

This adjustment provides optimum focus of the display for your vision.

Inspecting Connectors

The VS 300 offers 3 methods of inspecting fiber optic connectors:

•

Viewing fiber-end images on the VS 300 display by looking directly into the

eyepiece. This method provides the 400X magnification (23-degree field

of view comparable to an 8" monitor viewed at a distance of 20").

•

Viewing fiber-end images on the external video monitor connected to the

VS 300. This method provides the 600X magnification on a 12" monitor

and requires a video cable and external video monitor.

•

Transferring fiber-end images to a PC for viewing, saving, and printing.

This method provides the 600X magnification on a 12" monitor and

requires a video cable and computer that is equipped with an external or

internal NTSC video digitizer.
