Appendix C: Inspection and Cleaning

Inspect and clean the instrument as often as operating conditions require. The
collection of dirt can cause instrument overheating and breakdown. Dirt acts as
an insulating blanket, preventing efficient heat dissipation. Dirt also provides an
electrical conduction path

that

can cause an instrument failure, especially under

high-humidity conditions.

CAUTION. To prevent damage avoid the use of chemical cleaning agents that
might damage the plastics used in this instrument. Use only deionized water
when cleaning the menu buttons or front-panel buttons. Use a ethyl 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 ESD.) Instead, use low
pressure compressed air (about 9 psi).

Using Table C–1 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 perfor-
mance. Immediately repair defects that could cause personal injury or lead to
further damage to the instrument.
