Safety Information

• 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 a single 9 V battery, 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.
