Electrostatic Discharge (ESD) Precautions
Almost all electrical components can be damaged by electrostatic
discharge (
ESD) during handling. Component damage can occur at
electrostatic discharge voltages as low as 50 volts.
The following guidelines will help prevent
ESD damage when servicing
the function generator or any electronic device.
Disassemble instruments only in a static-free work area.
Use a conductive work area to dissipate static charge.
Use a conductive wrist strap to dissipate static charge accumulation.
Minimize handling.
Keep replacement parts in original static-free packaging.
Remove all plastic, styrofoam, vinyl, paper, and other static-generating
materials from the immediate work area.
Use only anti-static solder suckers.
WARNING
SHOCK HAZARD. Only service-trained personnel who are aware
of the hazards involved should remove the instrument covers.
To avoid electrical shock and personal injury, make sure to
disconnect the power cord from the function generator before
removing the covers.
Surface Mount Repair
Surface mount components should only be removed using soldering irons
or desoldering stations expressly designed for surface mount components.
Use of conventional solder removal equipment will almost always result in
permanent damage to the printed circuit board and will void your Agilent
factory warranty.
