Appendix G: 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 efficient heat dissipation. Dirt also
provides an electrical conduction path that can cause an instrument failure,
especially under high-humidity conditions.
Exterior Inspection
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. Have a qualified
service technician immediately repair defects that could cause personal injury or
lead to further damage to the instrument.
Exterior Cleaning
Perform the following steps when you clean the exterior of the instrument:
1. Remove loose dust on the outside of the instrument with a lint-free cloth.
2. Remove remaining dirt with a lint-free cloth dampened with a general purpose
detergent-and-water solution. Do not use abrasive cleaners.
3. Clean the monitor screen with a lint-free cloth dampened with a gentle, general
purpose detergent-and-water solution.
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% 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 Electro Static Discharge (ESD).
Instead, use low-pressure compressed air (about 9 psi).
WARNING.
To avoid injury or death, unplug the power cord from the line voltage
before cleaning the instrument. Avoid getting moisture inside the instrument during
external cleaning. Use only enough liquid to dampen the cleaning cloth.
