AFG3000 Series Arbitrary/Function Generators Service Manual 6-3
Inspection and Cleaning
procedures
The collection of dirt on internal components can cause them to overheat and fail.
Dirt also provides an electrical conduction path
that could cause an
arbitrary/function generator failure, especially under high-humidity conditions.
Inspect the arbitrary/function generator as often as operating conditions require.
Exterior Inspection. Inspect the outside of the arbitrary/function generator for
damage, wear, and missing parts, using Table 6-1 as a guide. Arbitrary/function
generator that appears to have been dropped or otherwise abused should be
checked thoroughly to verify correct operation and performance. Immediately
repair defects that could cause personal injury or cause further arbitrary/function
generator.
Exterior Cleaning Procedure. Do the following steps to clean the arbitrary/function
generator exterior:
1. Remove loose dust on the outside of the arbitrary/function generator with a
lint-free cloth. Use care to avoid scratching the clear glass display shield.
2. Remove remaining dirt with a lint free cloth dampened in a general purpose
detergent-and-water solution. Do not use abrasive cleaners.
CAUTION. Avoid the use of chemical cleaning agents which might damage the
plastics used in this AFG3000 Series arbitrary/function generator. Use only
deionized water when cleaning the front-panel buttons. Use an ethyl alcohol
solution as a cleaner and rinse with deionized water.

To avoid damage to the surface of the arbitrary/function generator, do not use any
abrasive or chemical cleaning agents.
