4 OPERATION
Maintenance
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. Power off the device.
2. Remove the test adapter from the optical connection
(see page 14).
The plug end surface is now accessible.
3. Wipe off the plug end surface using a cotton bud
soaked in isopropanol. This is a particularly effective
way of cleaning which leaves no residues.
4. Blow out the test adapter with clean compressed air
(available in spray cans, e.g. Anti Dust Spray).
Tip: 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 has become dirty through use, it can be
cleaned using a soft cloth moistened with a mild solution
of detergent.
⇒ Parts which have become very dirty may also be
cleaned carefully using alcohol.
CAUTION
Damage of device
Cleaning solution getting inside the
instrument can damage or destroy the
device.
! Make sure that the cleaning solution
does not get inside the instrument.
