VS300 Series Quick Reference Guide
The VS 300 is a complete video microscope system in a handheld and directly
viewed package. The VS 300 view safe microscope removes concerns for
eye safety while inspecting optical fiber connectors. The design of this video
microscope eliminates the optical path to the eye by utilizing a miniature
camera and a state-of-the-art microdisplay that achieves unparalleled clarity
and resolution.
Magnification of the VS 300 inspection scope is equivalent to 400X (23degree field of view comparable to an 8” monitor viewed at a distance of 20”)
and provides 600X when images are displayed on a 12” monitor connected to
the VS 300. The VS 300 video microscope uses thread-on adapter caps and
has an energy saving automatic shutoff.
The VS 300 is supplied with a 2.5mm Universal adapter cap and neck strap.
For greatest inspection flexibility additional adapter cap styles are available
from Noyes. For a list of available adapter caps contact Noyes, or visit our web
at www.AFLtele.com/go/Noyes.
Optical ports and connector end faces must be kept free from dirt or other
contaminates to ensure accurate measurements and operation. For cleaning
connector end faces on test jumpers and in fiber frames or adapters, use
optical quality cleaning fluid such as AFL FCC2 connector cleaning fluid and
AFL CCT molded cleaning tips. For cleaning the lenses and adapter caps, use
lint-free optical cleaning wipes such as AFL FiberWipes and optical quality
cleaning fluid such as AFL FCC2 connector cleaning fluid (or IPA - reagent
grade isopropyl alcohol 99% or better).

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.
1. Turn on the VS 300 inspection scope.
2. 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.

Centering Images/Panning Ferrule
If the fiber-end image is not centered in the display, the adapter cap and
adapter cap mount may be moved by hand to correct the problem.
1. Loosen the locking ring.
2. Apply left/right or front/back pressure on the adapter cap and the fiberend image will move accordingly on the display (motion will be reversed
when viewed on an external monitor).
3. When centering a fiber-end image or viewing ferrule is complete, tighten
the locking ring.
Note: The VS 300 is a complex imaging system. Occasionally, an image
may not appear after the instrument is powered up. To correct this problem,
remove and reinstall the batteries.

Viewing Fiber Ends
Transferring Images to a PC or Video Monitor
To inspect fiber optic connectors by viewing fiber-end images on the external
video monitor or transfer images to a PC, perform the following steps:
1. Select the appropriate video cable.
2. Plug one end of the video cable into the video Out port on the VS 300.
3. Plug the other end into a video In port on the external video monitor or
PC video capture device. Refer to the digitizer’s manual for additional
information on capturing, saving, and printing images.
After focusing is complete, the magnified view will reveal the condition of the
core and cladding. Below are the various examples of fiber ends ranging from
excellent to very poor conditions.
Excellent condition
Lint or dust
Cleaning residue
Scratches and dirt

Safety Information
WARNING! Use only the specified AC adapter. Use of another type of
AC adapter can damage the instrument and create the danger of fire and
electrical shock.
CAUTION! To avoid serious eye injury, never look directly into the optical
outputs of fiber optic network equipment, test equipment, patch cords, or test
jumpers. Always assume that optical outputs are on.
NOTICE! The VS 300 inspection scope contains no user serviceable parts.
Except for changing batteries and cleaning optical ports, these units must be
returned to Noyes or authorized agents for repair and calibration.
IMPORTANT! Although the VS 300 inspection scope has been designed to
operate in a wide range of environmental conditions, care should be taken
when handling or storing any precision optical equipment such as the VS 300
inspection scope.
