Cleaning the test port
It is a good idea to check that the optical connections are clean
and clean them if necessary before starting measurements. Even
very small dust particles on the end surfaces of the plugs or in
the test adapters can adversely affect the accuracy of the
measurement.
1. Switch off the instrument.
2. Remove the test adapter from the optical connection.
The plug end surface is now accessible.
3. Wipe off the plug end surface using a cotton bud soaked in
isopropanol.
This cleaning method is very effective and leaves no residue.
4. Blow out the test adapter with clean compressed air (available
in spray cans, e.g. anti-dust spray).
Notes: Cover the optical connections with the dust cap
whenever they are not in use. This prevents them from
getting dirty.
WARNING
Dangerous voltage and invisible laser radiation
Maintenance or cleaning of the instrument while it is con-
nected or operating may damage the instrument or injure
you.
► Make sure that the instrument is switched off and
disconnected from all power sources and optical radiation
sources before maintenance or cleaning.
