Maintenance
This section describes procedures for preventive maintenance, troubleshooting
methods, corrective maintenance, and procedures for recalibrating those
assemblies that normally do not require routine calibration.
Static Sensitive Components
This instrument contains electrical components that can be damaged by static
discharge. See Table 6--1 for the relative susceptibility of various classes of
semiconductors. S tatic voltages of 1 kV to 30 kV can occur in unprotected
environments.
Observe the following precautions to avoid damage:
H Minimize handling of static sensitive components.
H Transport and store static sensitive components or assemblies in their
original containers, on metallized or conductive foam. Label packages that
contain static sensitive assemblies or components.
H Discharge body static voltage by wearing a grounded wrist strap while
handling these components. Static sensitive assemblies or components
should be handled and serviced only at static free work stations by qualified
service personnel.
H Nothing capable of generating or holding a static charge should be allowed
on the work station surface.
H Keep the component leads shorted together whenever possible.
H Pick up components by the body, never by the leads.
H Do not slide the components over any surface.
H Avoid handling components in areas that have a floor or work surface
covering capable of generating a static charge.
H Use a soldering iron that is connected to earth ground.
H Use only antistatic suction or wick type desoldering tools.
