• 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, please have the meter inspected
by a qualified technician.
• Do not test voltage exceeding rated voltage marked
on the meter (600V).
• When testing voltage exceeding 30V AC voltage RMS,
42V AC peak or 60V DC, be particularly careful to
avoid electric shock.
• When measuring, use correct jack, and select the
proper function.
• Do not use the meter in explosive gas, vapor or dusty
environments.
• When using the probe, fingers should be behind the
probe protection device.
• Before measuring resistance, continuity, first turn off
power and discharge all high voltage capacitors.
• If the meter is not used in accordance with the
instructions, the meter's safety protective function
may become invalid.
• When opening the case (or part of the case), turn
the meter off.
• When the battery low voltage indicator «
becomes lit, replace the battery at once. A low battery
will cause meter reading errors and may result in
electric shock or personal injury.
• Before opening the case or the battery cover, remove
the test wires from the meter.
• When maintaining the meter, use replacement parts
specified by the factory.
