Electrostatic discharge (ESD) considerations
N O T I C E
Potential Instrument Damage. Delicate internal electronic components can be damaged by static
electricity, resulting in degraded performance or eventual failure.
Refer to the steps in this procedure to prevent ESD damage to the instrument:
• Touch an earth-grounded metal surface such as the chassis of an instrument, a metal conduit or
pipe to discharge static electricity from the body.
• Avoid excessive movement. Transport static-sensitive components in anti-static containers or
packages.
• Wear a wrist strap connected by a wire to earth ground.
• Work in a static-safe area with anti-static floor pads and work bench pads.
