Inspection and Cleaning
Inspection and Cleaning describes how to inspect for dirt and damage on
and how to clean the exterior and interior of the oscilloscope. You should
perform inspection and cleaning as preventive maintenance. Preventive
maintenance, when done regularly, may prevent oscilloscope malfunction
and enhance its reliability.
Preventive maintenance consists of visually inspecting and cleaning the
oscilloscope and using general care when operating it.
How often to do maintenance depends on the severity of the environment in
which you use the oscilloscope. A proper time to perform preventive mainteĆ
nance is just before oscilloscope adjustment.
CAUTION
Static discharge can damage any semiconductor component in this
oscilloscope.
Precautions
When performing any service which requires internal access to the oscilloĆ
scope, adhere to the following precautions to avoid damaging internal
modules and their components due to electrostatic discharge (ESD).
1. Minimize handling of staticĆsensitive modules.
2. Transport and store staticĆsensitive modules in their static protected
containers. Label any package that contains staticĆsensitive modules.
3. Discharge the static voltage from your body by wearing a grounded
antistatic wrist strap while handling these modules. Do service of
staticĆsensitive modules only at a staticĆfree work station.
4. Do not remove the oscilloscope cabinet unless you have met precaution
number 3, above. Consider all internal modules staticĆsensitive.
5. Nothing capable of generating or holding a static charge should be
allowed on the work station surface.
6. Handle circuit boards by the edges when possible.
7. Do not slide the modules over any surface.
