Warnings and Precautions

• This instrument is EN61010-1:2001 and EN61010-2-32 certified for
Installation Category III. It is recommended for use with local level
power distribution, appliances, portable equipment, etc, where only
smaller transient overvoltages may occur, and not for primary
supply lines, overhead lines and cable systems.
• This instrument must not be used on uninsulated conductors at a
voltage greater than 600V ac/dc.
• Use extreme caution when working around bare conductors and bus
bars.
• Do not exceed the instrument overload limits per function (see
specifications) nor the limits marked on the instrument.
• Exercise extreme caution when: measuring voltage >60 V DC or 30 V
AC RMS // current >10 mA // AC power lines with inductive loads //
AC power lines during electrical storms // servicing CRT equipment.
High voltages can be lethal and high voltage transients may occur at
any time.
• Never measure current while test leads are inserted in the input
jacks.
