Safety Information
A “XW Warning” statement defines hazardous conditions
and actions that could cause bodily harm or death.
A “W Caution” statement identifies conditions and actions
that could damage the Meter or the equipment under test.
XWRead First: Safety Information
To ensure safe operation and service of the
Meter, follow these instructions:
•Read the Users Manual before use and
follow all safety instructions.
•Use the Meter only as specified in the
Users Manual; otherwise, the Meter's
safety features may be impaired.
•Avoid working alone so assistance can be
rendered.
•Never use the Meter on a circuit with
voltages higher than 600 V or a frequency
higher than 400 Hz fundamental. The Meter
may be damaged.
•Never measure ac current while the test
leads are inserted into the input jacks.
•Do not use the Meter or test leads if they
look damaged.
•Use extreme caution when working around
bare conductors or bus bars. Contact with
the conductor could result in electric
shock.

•Use caution when working with voltages
above 60 V dc or 30 V ac rms or 42 V ac
peak. Such voltages pose a shock hazard.
•Clean the case with a damp cloth and mild
detergent only. Do not use abrasives or
solvents.
•To avoid false readings that can lead to
electrical shock and injury, replace the
batteries as soon as the low battery
indicator (B) appears. As the Meter gets
to the point where the low batteries affect
the readings, the Meter locks and no
measurements can be made until the
batteries are changed.
•Do not hold the Meter anywhere beyond
the tactile barrier, see Figure 1.
•Adhere to local and national safety codes.
Individual protective equipment must be
used to prevent shock and arc blast injury
where hazardous live conductors are
exposed.
