AFL VS300 Series Quick Reference Manual

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 (23- degree 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).

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. 1. Slowly turn the eyepiece clockwise/counterclockwise until edges of the 2. 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.

Select an adapter cap that matches the connector to be inspected. 1. Mount the selected adapter cap on the VS 300 inspection port. 2. Insert the cable to be inspected in the adapter cap. 3. Turn on the VS 300 either by pressing the power button or by connecting 4. an AC adapter. Slowly adjust the focus knob to focus the fiber-end image on the camera. 5.

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. Loosen the locking ring. 1. Apply left/right or front/back pressure on the adapter cap and the fiber- 2. end image will move accordingly on the display (motion will be reversed when viewed on an external monitor). When centering a fiber-end image or viewing ferrule is complete, tighten 3. 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. L O C K U N L O C K Locking ring Adapter cap Focus knob
