TPS2000 Series Digital Storage Oscilloscopes Service Manual
H
Transport and store static-sensitive modules in their static protected
containers or on a metal rail. Label any package that contains static-sensitive
modules.
H
Discharge the static voltage from your body by wearing a grounded antistatic
wrist strap while handling these modules.
H
Service static-sensitive modules only at static-free workstations. Do not
allow anything capable of generating or holding a static charge on the
workstation surface.
H
Handle circuit boards by the edges when possible.
H
Do not slide the modules over any surface.
H
Avoid handling modules in areas that have a floor or work-surface covering
capable of generating a static charge.
Inspection and Cleaning
This section describes how to inspect for dirt and damage, and how to clean the
oscilloscope. Inspection and cleaning are done as preventive maintenance which,
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. Perform preventive
maintenance more often if you operate the oscilloscope in a severe environment.
A good time to perform preventive maintenance is just before adjustment of the
oscilloscope.
For optimum performance, follow these recommendations:
H
Protect the oscilloscope from adverse weather conditions. The oscilloscope is
not waterproof.
H
Do not store or leave the oscilloscope where the liquid crystal display (LCD)
will be exposed to direct sunlight or high humidity for long periods of time.
H
The front and rear cases help keep dust out of the oscilloscope and must be in
place during normal operation.
H
To avoid damage to the oscilloscope or probes, do not expose them to any
sprays, liquids, or solvents.
The accumulation of dirt on internal components can cause them to overheat and
fail. Dirt also provides an electrical conduction path that could cause an oscillo-
scope failure, especially under high-humidity conditions. Inspect and clean the
oscilloscope and probes as often as operating conditions require.
