PRECAUTIONS
WARNING: Measure known voltage with the meter to
verify that the meter is working properly. If the meter is
working abnormally, stop using it immediately. A protective
device may be damaged. If there is any doubt, have the
meter inspected by a qualified technician.
WARNING:Do not use the meter or test leads if they look
damaged. Check to see if the test wire has insulation
damage or bare metal. Check test wire continuity. If the
wire is damaged, replace it with a new one before using the
meter.
WARNING: When testing voltage that exceeds 30V AC or
60V DC, be particularly careful to avoid electric shock.
WARNING: When measuring, use the correct jack, and
select the proper function and measuring range.
WARNING: When making 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.
WARNING: Do not use under direct sunlight or high
temperatures.
WARNING: Disconnect power to the circuits and
discharge all high-voltage capacitors before testing
resistance, continuity, diodes, or capacitance.
WARNING:Before measuring current, check the meter’s
fuse and turn off power to the circuit before connecting the
meter to the circuit.
WARNING: Do not measure voltages exceeding the rated
voltage marked on the meter.
WARNING: Do not operate the meter with any part
removed or damaged.
WARNING: When the battery low voltage indicator
illuminates, replace the battery immediately. A low battery
will cause meter reading errors and may result in electric
shock or personal injury.
WARNING: Do not operate the meter around explosive
gas, vapor, or dust.
CAUTION: Pay attention to the battery polarity when
changing the battery.
CAUTION: When maintaining the meter, use replacement
parts specified by the factory.
CAUTION: To avoid damage to the meter, do not exceed
the maximum limits of the input values shown in the
Specification tables.
CAUTION: Before changing functions, disconnect the test
leads from the circuit under test.
NOTE: Keep your fingers behind the protection guards
while measuring.
