Inspect and clean the instrument and probes as often as operating conditions
require. The collection of dirt on internal components can cause them to overheat
and breakdown. Dirt also provides an electrical conduction path
that could cause
an instrument failure, especially under high-humidity conditions.
Inspection — Exterior. Inspect the outside of the instrument for damage, wear, and
missing parts. Instruments that appear 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 lead to further
damage to the instrument.
Cleaning Procedure — Exterior. To clean the instrument exterior and probes,
perform the following steps:
1. Remove loose dust on the outside of the instrument and probes with a lint
free cloth. Use care to avoid scratching the clear plastic display shield.
2. Use a soft cloth dampened with water to clean the instrument. You can use a
75% isopropyl alcohol solution for more efficient cleaning.
CAUTION. To avoid damage to the surface of the instrument or probes, do not use
any abrasive or chemical cleaning agents.
Inspection — Interior. During normal use, the instrument case guards the internal
components against common dust and dirt. However, if it appears that the
instrument may have been damaged or has been exposed to an unusually dirty
environment, you should inspect and clean the interior.
To inspect and clean the interior, disassemble the instrument by completing each
of the disassembly procedures in the order given starting on page 6–12.
Inspect the internal portions of the instrument for damage and wear using
Table 6–1 as a guide. Defects found should be repaired immediately.
