4. Press Take Reference. After a few seconds, the unit displays new
reference values for each wavelength. If values are not acceptable, try
to clean connectors and repeat this step.
5. Disconnect the reference patchcord from the power meter adapter
only and connect it to the fiber under test.
6. Repeat the procedure with the second unit.
IMPORTANT
You can turn off the unit without losing the reference.
If you disconnect the patchcord from the FASTEST port, you must
take a new reference.
