Inspection and Cleaning
Inspect and clean the instrument as often as your operating conditions require.
The collection of dirt can cause instrument overheating and operational failure.
Dirt acts as an insulating blanket, preventing ef
fi
cient heat dissipation. Dirt
also provides an electrical conduction path that can cause an instrument failure,
especially under high-humidity conditions.
CAUTION.
Avoid the use of chemical cleaning agents that might damage the
plastics used in this instrument. Use only deionized water when cleaning the
front-panel controls. Use a 75% Isopropyl alcohol solution as a cleaner, and rinse
with deionized water.
Avoid the use of high-pressure compressed air when cleaning dust from the
interior of this instrument. High-pressure air can cause Electro Static Discharge
(ESD). Instead, use low-pressure compressed air (about 9 psi).
Exterior Inspection
Using the following table as a guide, inspect the outside of the instrument for
damage, wear, and missing parts. You should thoroughly check instruments that
appear to have been dropped or otherwise abused to verify correct operation and
performance. Immediately repair defects that could cause personal injury or lead
to further damage to the instrument.
