Getting Started
•
Remove test leads from the Meter before opening the
battery door.
•
Inspect the test leads for damaged insulation or
exposed metal. Check the test leads for continuity.
Replace damaged test leads before you use the Meter.
•
Do not apply more than the rated voltage, as marked
on the Meter, between the terminals or between any
terminal and earth ground.
•
Never operate the Meter with the cover removed or the
case open.
•
Use caution when working with voltages above 30 V ac
rms, 42 V ac peak, or 60 V dc. These voltages pose a
shock hazard.
•
Use only the replacement fuses specified by the
manual.
•
Use the proper terminals, function, and range for
measurements.
•
Avoid working alone.
•
When measuring current, turn off circuit power before
connecting the Meter in the circuit. Remember to
place the Meter in series with the circuit.
•
When making electrical connections, connect the
common test lead before connecting the live test lead;
when disconnecting, disconnect the live test lead
before disconnecting the common test lead.

•
Do not use the Meter if it operates abnormally.
Protection may be impaired. When in doubt, have the
Meter serviced.
•
Do not operate the Meter around explosive gas, vapor,
or dust.
•
Use only 1.5 V AA batteries, properly installed in the
Meter case, to power the Meter.
•
When servicing the Meter, use only specified
replacement parts.
•
When using probes, keep fingers behind the finger
guards on the probes.
•
Do not use the Low Pass Filter option to verify the
presence of hazardous voltages. Voltages greater than
what is indicated may be present. First, make a
voltage measurement without the filter to detect the
possible presence of hazardous voltage. Then select
the filter function.
•
Only use test leads that have the same voltage,
category, and amperage ratings as the meter and that
have been approved by a safety agency.
•
Use proper protective equipment, as required by local
or national authorities when working in hazardous
areas.
•
Comply with local and national safety requirements
when working in hazardous locations.
