Verify that the reference test cord is connected to the
tester's INPUT port and that all other connections are
secure.
Verify that the wavelength you selected on the tester
matches the source's wavelength.
If you are measuring the output of a source used for
testing, verify that the source's output is set to
continuous wave. The modulated output produces a
lower power reading than the continuous wave
output.
Verify that all patch cords and adapters are good and
are of the appropriate type and core size for the
source.

If you are measuring the power received through
cabling, use the OTDR to check the cabling for faults.
Disconnect the source before connecting the
OTDR to the cabling. Live sources can damage the
OTDR’s receiver.
Clean all fiber connections, then retest.
Use a fiber microscope, such as the Fluke Networks
FiberInspector probe, to inspect the fiber connectors.
Polish the connectors if necessary, then retest.
