8. Avoid handling modules in areas that have a floor or workĆsurface coverĆ
ing capable of generating a static charge.
9. Do not use highĆvelocity compressed air when cleaning dust from
modules.
The cabinet helps keep dust out of the oscilloscope and it is a major compoĆ
nent of its cooling system. It should normally be in place when operating the
oscilloscope. The optional oscilloscope front cover protects the front panel
and display from dust and damage. Install it when storing or transporting the
oscilloscope.
Inspect and clean the oscilloscope as often as operating conditions require.
The collection of dirt on components inside can cause them to overheat and
breakdown. (Dirt acts as an insulating blanket, preventing efficient heat
dissipation.) Dirt also provides an electrical conduction path that could cause
an oscilloscope failure, especially under highĆhumidity conditions.
CAUTION
Avoid the use of chemical cleaning agents that might damage the
plastics used in this oscilloscope. Use only deionized water when
cleaning the menu buttons or frontĆpanel buttons. Use a 75%
isopropyl alcohol solution as a cleaner and rinse with deionized
water. Before using any other type of cleaner, consult your Tektronix
Service Center or representative.
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).
Inspection Ċ Exterior
Using Table 6Ć1 as a guide, inspect the outside of the oscilloscope for damĆ
age, wear, and missing parts. You should thoroughly check oscilloscopes
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 oscilloscope.
