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 instrument 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.
W A R N I N G
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 instrument 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.
