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.

902

Users Manual

•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.
