Maintenance
Do not allow anything capable of generating or holding a static charge on the
work station surface.

Do not slide the modules over any surface.
Avoid handling modules in areas that have a fl oor or work-surface covering
capable of generating a static charge.
Inspection and Cleaning
Inspection and Cleaning describes how to inspect for dirt and damage, and how to
clean the exterior and interior of the instrument. Inspection and cleaning are done
as preventive maintenance. Preventive maintenance, when done regularly, may
prevent instrument malfunction and enhance its reliability.
Preventive maintenance consists of visually inspecting and cleaning the
instrument and using general care when operating it.
How often to do maintenance depends on the severity of the environment in which
the instrument is used. A proper time to perform preventive maintenance is just
before instrument adjustment.
General Care For optimum performance, follow these recommendations:
Protect the instrument from adverse weather conditions. The instrument is
not waterproof.
Do not store or leave the instrument where the liquid crystal display (LCD)
will be exposed to direct sunlight or high humidity for long periods of time.
The cabinet helps keep dust out of the instrument and must be in place during
normal operation.
To avoid damage to the instrument, do not expose it to any sprays, liquids,
or solvents.
