wavelength, select that wavelength both at the
Power Meter unit and the source unit. Press F3 to
change the wavelength for the Fiber Meter Power

Once the reference measurement has been made and you
are ready to begin testing, do not disconnect the test
jumper from the optical source (TX port of the Fiber Meter
handset.) Disconnecting the test jumper from the optical
source will affect the reference and will require
re-establishing references at 850 nm and 1300 nm.
