The opening of covers or removal of parts is likely to expose the user to
dangerous voltages. Disconnect the instrument from all voltage sources before
being opened.
Electrostatic Discharge Protection
Electrostatic discharge (ESD) can damage or destroy electronic components. The instrument is
shipped in materials that prevent damage from static, and should only be removed from the
packaging in an anti-static area ensuring that the correct anti-static precautions are taken.
Two types of ESD protection are listed below. Purchase acceptable ESD accessories from your
local supplier.
• Conductive table-mat and wrist-strap combination
• Conductive floor-mat and heal-strap combination
Both types, when used together, provide a significant level of ESD protection. To ensure user
safety, static-safe accessories must provide at least 1 M
Ω
of isolation from ground.
