Preventive maintenance mainly consists of periodic cleaning. Periodic cleaning
reduces instrument breakdown and increases reliability. Clean the instrument as
needed, based on the operating environment. Dirty conditions may require more
frequent cleaning than computer room conditions.
The flat panel display is a soft plastic display and must be treated with care
during cleaning.
CAUTION.
Improper cleaning agents or methods can damage the flat panel
display.
Do not use abrasive cleaners or commercial glass cleaners to clean the display
surface.
Do not spray liquids directly on the display surface.
Do not scrub the display with excessive force.
Avoid getting moisture inside the instrument while cleaning the display; use
only enough solution to dampen the wipe.
Clean the flat panel display surface by gently rubbing the display with a
cleanroom 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.
Clean the exterior surfaces with a dry, lint-free cloth or a soft-bristle brush. If dirt
remains, use a cloth or swab dampened with a 75% isopropyl alcohol solution. A
swab is useful for cleaning in narrow spaces around the controls and connectors.
Do not use abrasive compounds on any part of the instrument.
To avoid damaging the instrument follow these precautions:
Avoid getting moisture inside the instrument during external cleaning and use
only enough solution to dampen the cloth or swab.
Do not wash the front-panel power switch. Cover the switch while washing
the instrument.
Use only deionized water when cleaning. Use a 75% isopropyl alcohol
solution as a cleanser and rinse with deionized water.
Do not use chemical cleaning agents; they may damage the instrument. Avoid
chemicals that contain benzene, toluene, xylene, acetone, or similar solvents.
