Warning
To prevent possible electrical shock or personal injury, follow these guidelines:
•Use the Meter only as specified in this manual or the protection provided by the
Meter can be compromised.
•Examine the case before you use the Meter. Look for cracks or missing plastic.
Carefully look at the insulation around the connectors.
•Never measure current while the test leads are inserted into the input jacks.
•Make sure the battery door is closed and latched before operating the Meter.
•Remove the test leads from the Meter before the battery door is opened.
•Examine the test leads for damaged insulation or exposed metal. Check test lead
continuity. Replace damaged test leads before using the Meter.
•Do not use the Meter if it operates incorrectly. Protection can be compromised.
When in doubt, have the Meter serviced.
•Do not use the Meter around explosive gas, vapor or in damp or wet
environments.
•Use only type AA batteries, properly installed in the Meter case, to power the
Meter.
•When measuring, keep fingers behind the Tactile Barrier. See "The Meter" .
•To avoid false readings that can lead to electrical shock and injury, replace the
batteries as soon as the low battery indicator () appears.
•When servicing the Meter, use only specified replacement parts.

•Have the Meter serviced only by qualified service personnel.
•Be careful around voltages >30 V ac rms, 42 V ac peak, or 60 V dc. Such voltages
pose a shock hazard.
•Do not apply more than the rated voltage, as marked on the Meter, between the
terminals or between any terminal and earth ground.
•When using the probes, keep fingers behind the finger guards on the probes.
•Connect the common test lead before connecting the live test lead. When
disconnecting test leads, disconnect the live test lead first.
•Do not work alone so assistance can be rendered in an emergency.
•Use extreme caution when working around bare conductors or bus bars. Contact
with the conductor could result in electric shock.
•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.
•Disconnect circuit power and discharge all high-voltage capacitors before you
do diode tests or measure resistance or continuity.
•Do not measure ac/dc current in circuits carrying more than 600 V or 200 A with
the Meter Jaw.
•Never operate the Meter with the back cover removed or the case open.
