To connect the appropriate adapter tip, place the tip on the end of the probe. Carefully screw
the adapter to the Adapter Tip Ring completely and finger tight only. DO NOT HOLD OR TURN
THE FOCUS RING WHILE ATTACHING THE ADAPTER TIP. For bulkhead adapters, it is helpful to
align the key of the adapter tip to the center position facing the user.
2. Focus Ring – Two focus methods are used to adjust the image while using the VIS 300. The first
technique is used when using any of the “universal” tips for direct connector inspection. To
focus, insert the connector into the adapter tip and adjust the image by turning the Focus Ring
with the users thumb.
To focus on the bulkhead connector surface, the VIS 300 uses a unique focus system by use of
specially equipped adapter tips. These bulkhead tips include key way devices to lock the VIS
probe into the bulkhead under inspection. To focus on the bulkhead, simply insert the bulkhead
adapter tip into the bulkhead and rotate the probe slightly either direction for full focus
control. The probe may be held anywhere while rotating, allowing for much easier focus
control.
3. Probe Body – The Probe Body houses the optical interface, camera system and lighting system.
The probe body houses no user serviceable devices inside the housing. Please refer to the
maintenance section for proper care of the optical interface at the tip of the probe.
