10. Use only approved antistatic, vacuum-type desolder
ing tools for component removal.
PREVENTIVE MAINTENANCE
INTRODUCTION
Preventive maintenance consists of cleaning, visual
inspection, lubrication, and checking instrument
performance. When accomplished regularly, it may prevent
instrument malfunction and enhance instrument reliability.
The severity of the environment in which the instrument is
used determines the required frequency of maintenance. An
appropriate time to accomplish preventive maintenance is
just before instrument adjustment.
GENERAL CARE
The cabinet minimizes accumulation of dust inside the
instrument and should normally be in place when operating
the 2213. The optional front-panel cover provides both
dust and damage protection for the front panel and crt
face, and it should be in place whenever the instrument is
stored or is being transported.
INSPECTION AND CLEANING
The instrument should be visually inspected and cleaned
as often as operating conditions require. Accumulation of
dirt in the instrument can cause overheating and com
ponent breakdown. Dirt on components acts as an
insulating blanket, preventing efficient heat dissipation. It
also provides an electrical conduction path that could result
in instrument failure, especially under high-humidity
conditions.
> CAUTION (
Avoid the use o f chemical cleaning agents which
might damage the plastics used in this instrument.
Use a nonresidue-type cleaner, preferably isopropyl
alcohol, denatured ethyl alcohol, or a solution o f 1%
m ild detergent with 99% water. Before using any
other type of cleaner, consult your Tektronix Service
Center or representative.
Exterior
INSPECTION. Inspect the external portions of the
instrument for damage, wear, and missing parts; use
Table 6-2 as a guide. Instruments that appear to have been
dropped or otherwise abused should be checked thoroughly
to verify correct operation and performance. Deficiencies
found that could cause personal injury or could lead to
further damage to the instrument should be repaired
immediately.
To prevent getting moisture inside the instrument
during external cleaning, use only enough liquid to
dampen the doth or applicator.
CLEANING. Loose dust on the outside of the instru
ment can be removed with a soft cloth or small soft-bristle
brush. The brush is particularly useful for dislodging dirt
on and around the controls and connectors. Dirt that
remains can be removed with a soft cloth dampened in a
mild detergent-and-water solution. Do not use abrasive
cleaners. Clean the light filter and the crt face with a soft
lint-free cloth dampened with either denatured alcohol or
a mild detergent-and-water solution.
Interior
To gain access to internal portions of the instrument for
inspection and cleaning, refer to the "Removal and
Replacement Instructions" in the "Corrective Maintenance"
part of this section.
INSPECTION. Inspect the internal portions of the
instrument for damage and wear, using Table 6-3 as a guide.
Deficiencies found should be repaired immediately. The
corrective procedure for most visible defects is obvious;
however, particular care must be taken if heat-damaged
components are found. Overheating usually indicates other
trouble in the instrument; therefore, it is important that the
cause of overheating be corrected to prevent recurrence
of the damage.
