Normalizing
To ensure a high measurement accuracy, it is required to
normalize the unit from time to time. This is done with the
port open, i.e. no DUT is connected.
To normalize the unit:
1. Disconnect DUT from test port.
The normalization can be performed only with an open
test port.
2. Unmount test adapter from test port, clean fibre
surface of test port and mount test adapter.
3. Switch on laser.
4. Press
[MENU ENTER]
to open the ORL MAIN menu.
