WARNING AND PRECAUTION
o avoid possible electric shock or personal injury, and to avoid possible damage to the meter or
to the equipment under test, comply with the follow practices:
• Do not use the meter if it is damaged. Before you use the meter, inspect the case. Pay
particular attention to the insulation surrounding the connectors.
• 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 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.
• Do not apply more than the rated voltage, as marked on the meter, between terminals or
between any terminal and earth ground.
• Before use, verify the meter's operation by measuring a known voltage.
• When measuring current, turn off circuit power before connecting the meter in the circuit.
• When servicing the meter, use only specified replacement parts. Do not use the Meter in a
manner not specified by this manual, or the safety features of the Meter may be impaired.
• Use with caution when working above 30V ac rms, 42V peak, or 60V dc. Such voltages pose a
shock hazard.
