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 modular DMM 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 antistatic solder remover.
