Cleaning the Output Port
Cleaning all connectors before coupling them to the Fault Finder ensures proper
maintenance of the output port and laser lens. Always cover the output port with the
dust cap when you're not using the Fault Finder.
If binding or stickiness is felt when inserting connectors into the output port, the
ceramic sleeve should be cleaned. Insert a cleaning wand (not included) into the
output port until it stops. Twist the wand, remove it, and discard. Do not reuse the
cleaning wand.
Cleaning the Laser Lens
If the intensity of the light output decreases considerably, despite the batteries
being in good condition, the laser lens is probably dirty. Loose dirt can be removed
by applying suction to the output port.
Do not blow air into the output port to remove dirt particles. Doing so
will only pack the dirt and make it harder to remove.
If the lens is extremely dirty, flush out the output port with a small amount of
reagent-grade isopropyl alcohol, then apply gently suction to remove any
remaining dirt. Make sure that all residual alcohol has evaporated before resuming
testing.
