Maintenance
How often you do maintenance depends on the severity of the environment in
which the oscilloscope is used. A proper time to perform preventive maintenance
is just before oscilloscope adjustment.
General Care The cabinet helps keep dust out of the oscilloscope and should normally be in
place when operating the oscilloscope.
WARNING.
To avoid injury, power off the instrument and disconnect it from line
voltage before performing any procedure that follows.
Flat Panel Display Cleaning The display is a soft plastic display and must be treated with care during cleaning.
CAUTION.
Improper cleaning agents or methods can damage the fl at panel
display.
Avoid using abrasive cleaners or commercial glass cleaners to clean the display
surface.
Avoid spraying liquids directly on the display surface.
Avoid scrubbing the display with excessive force.
Clean the fl at panel display surface by gently rubbing the display with a
clean-room wipe (such as Wypall Medium Duty Wipes, #05701, available from
Kimberly-Clark Corporation).
If the display is very dirty, moisten the wipe with distilled water or a 75%
isopropyl alcohol solution and gently rub the display surface. Avoid using excess
force or you may damage the plastic display surface.
Exterior Cleaning
CAUTION. To prevent getting moisture inside the oscilloscope during external
cleaning, use only enough liquid to dampen the cloth or applicator.
Clean the exterior surfaces of the chassis with a dry lint-free cloth or a soft-bristle
brush. If any dirt remains, use a cloth or swab dipped in a 75% isopropyl alcohol
solution. Use a swab to clean narrow spaces around controls and connectors. Do
not use abrasive compounds on any part of the chassis that might damage the
chassis.
