Other Cleaning Tools - HP E5970A User Manual

These are available from tobacco shops.
Ensure that the bristles of the pipe-cleaner are soft, so that they do not scratch
your device during cleaning.
Caution
Store your pipe-cleaner carefully and never reuse them as dust and dirt from
the air or from previous cleaning can scratch and dirty your optical device.
Compressed Air This is available from laboratory suppliers.
It is essential that your compressed air is free of dust, water and oil. Only use
clean, dry air. If you do not, it can lead to filmy deposits or scratches.
When using compressed air from a can,
rn Hold the can upright. A slant can cause propellant to escape with the
compressed air and dirty your optical device.
rn
Spray the first couple of seconds into the air, as the first stream of
compressed air can contain condensation or propellant. Any condensation
produces a filmy deposit.
If you are using compressed air from a can, you should select one with a
CFC-free propellant, for the sake of the environment.
Other Cleaning Tools
To examine devices you also require:
Microscope
Ultrasonic bath
Premoistened
cleaning wipes
Select a microscope with a magnification range of between 50X and 300X.
These should be available from photographic stores or laboratory suppliers.
Ensure that the light source of the microscope is flexible. This helps you to
examine your device closely and from different angles.
A microscope allows you to determine the type of dirt on your device and its
extent. Then you can choose the correct cleaning procedure and later to
examine the results of cleaning. With a microscope you can also decide if your
optical device is scratched.
These are typically available from photographic stores or laboratory suppliers.
An ultrasonic bath very gently removes greasy and other stubborn
dirt
from
optical devices.
Only use an ultrasonic bath with isopropyl alcohol, as other solvents can
damage or dirty your optical device.
These are available from HP. The part number is HP 92193N (80 Wipes per
box). These are tissues that are moistened with isopropyl alcohol.
