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.
Always inspect your instrument, test leads and accessories for
•
signs of damage or abnormality before every use. If abnormal
conditions exist (broken or damaged test leads, cracked case,
display not reading, etc.), do not use.
When making voltage measurements, make sure these
•
ranges function correctly. Take a reading of a known voltage
first.
