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).
NOTE:
Cover the optical connections with the dust cap whenever they
are not in use. This prevents them from getting dirty.
Cleaning the instrument
If the instrument gets dirty through use, you can clean it using a
soft cloth moistened with a mild solution of detergent.
