AM700 Audio Measurement Set Service Manual
6–3
H Keep the component leads shorted together whenever possible.
H Pick up the 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.
NOTE. A 2% RMA flux content solder is recommended for making repairs in this
instrument. Cleaning of rosin residue is not recommended. Most cleaning
solvents tend to reactivate the rosin and spread it under components where it
may cause corrosion under humid conditions. The rosin residue, if left alone,
does not exhibit these corrosive properties.
H Use only special antistatic, suction, or wick-type desoldering tools.
CAUTION. Any repair procedures should be performed only by qualified service
personnel. Performing these procedures incorrectly could damage the instru-
ment. Refer all repair and replacement procedures to a qualified service
technician.
