Exterior Inspection. Examine the outside of the generator for damage, wear, and
missing parts, using Table 6–2 as a guide. Waveform generators that appear to
have been dropped or otherwise mishandled should be checked thoroughly to
verify correct operation and performance. Immediately repair defects that could
cause personal injury or cause further generator damage.

pose detergent-and-water solution. Do not use abrasive cleaners.
3. Clean the light filter protecting the monitor screen with a lint-free cloth
dampened with either ethyl alcohol or preferably, a mild, general purpose

cleaning, use only enough liquid to dampen the cloth or applicator.
