Using the 2.5-mm "Quick Connect" Output Port
1. Insert the ferrule of a fiber optic connector into the "quick connect" output
port, ensuring that it seats completely. You should always clean the endface of
the connector before inserting it in the quick connect output port.
2. Rotate the switch to the desired operating mode by moving it to the right. The
first position puts the instrument in continuous wave (CW) mode. The second
position puts the instrument in blink (MOD) mode. The LED indicator on the
unit will light steadily in CW mode. It will blink in MOD mode.
3. See the Applications section for instructions on tracing faults in optical fibers.
Fault Finder Snap-On Connector Adapters
Optional Fault Finder snap-on connector adapters are available for ST, SC, and FC
fiberoptic connectors. These adapters fasten securely to fiberoptic connectors and
prevent them from pulling loose from the instrument. To use a snap-on connector
adapter with the Fault Finder, follow the steps below.
1. Select the appropriate Fault Finder snap-on connector adapter and press it
firmly over the quick connect output port.
2. Insert the connector under test into the adapter and secure it. Most fiberoptic
connectors are secured by turning the outer sleeve clockwise.
3. Rotate the switch to the desired operating mode.
