Maintenance
6–2 TDS3000 Series Service Manual
3. Discharge the static voltage from your body by wearing a grounded antistatic
wrist strap while handling these modules. Do service of static-sensitive
modules only at a static-free work station.
4. Nothing capable of generating or holding a static charge should be allowed
on the work station surface.
5. Handle circuit boards by the edges when possible.
6. Do not slide the modules over any surface.
7. Avoid handling modules in areas that have a floor or work-surface covering
capable of generating a static charge.
Inspection and CleaningThis section describes how to inspect for dirt and damage, and how to clean the
oscilloscope. Inspection and cleaning are done as preventive maintenance.
Preventive maintenance, when done regularly, may prevent malfunctions and
enhance 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 the oscillo-
scope is used. A proper time to perform preventive maintenance is just before
adjustment of the oscilloscope.
Protect the oscilloscope from adverse weather conditions. The oscilloscope is not
waterproof.
Do not store or leave the oscilloscope where the LCD display will be exposed to
direct sunlight for long periods of time.
CAUTION. To avoid damage to the oscilloscope, do not expose it to any sprays,
liquids, or solvents.
Inspect and clean the oscilloscope as often as operating conditions require. The
collection of dirt on internal components can cause them to overheat and
breakdown. Dirt acts as an insulating blanket, preventing efficient heat dissipa-
tion. Dirt also provides an electrical conduction path that could cause an
oscilloscope failure, especially under high-humidity conditions.
