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 reduce static charges.
 Use a conductive wrist strap to reduce static accumulation.
 Minimize handling.
 Keep replacement parts in original static-free packaging.
 Remove all plastic, foam, vinyl, paper, and other static-generating
materials from the immediate work area.
