Cleaning the test port
It is a good idea to check that the optical connections are
clean and to 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 device and disconnect it from all power
sources including at least one battery and any optical
radiation sources.
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 residues.
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.
