Section 6— 2230 Service
MAINTENANCE
This section contains information for conducting preventive maintenance, troubleshooting, and corrective maintenance on
the instrument. Circuit board removal procedures are included in the corrective maintenance part of this section.
STATIC-SENSITIVE COMPONENTS
The following precautions are applicable when perform
ing any maintenance involving internal access to the
instrument.
Static discharge can damage any semiconductor
component in this instrument.
This instrument contains electrical components that are
susceptible to damage from static discharge. Table 6-1
lists the relative susceptibility of various classes of sem
iconductors. Static voltages of 1 kV to 30 kV are common
in unprotected environments.
When performing maintenance, observe the following
precautions to avoid component damage:
1. Minimize handling of static-sensitive components.
2.
Transport and store static-sensitive components or
assemblies in their original containers or on a metal rail.
Label any package that contains static-sensitive com
ponents or assemblies.
3.
Discharge the static voltage from your body by
wearing a grounded antistatic wrist strap while handling
these components. Servicing static-sensitive components
or assemblies should be performed only at a static-free
work station by qualified service personnel.
4.
Nothing capable of generating or holding a static
charge should be allowed on the work station surface.
5.
Keep the component leads shorted together when
ever possible.
6.
Pick up components by their bodies, never by their
leads.
