SAFETY RULES:

• The DMM51FSG complies with IEC 1010-1 CAT I 1000V, CAT II 600V and CAT III
300V overvoltage standards. Use the meter only as specified in this manual,
otherwise the protection provided by the meter may be impaired.
• CAT I - For signal level, telecommunication, electronic with small transient over
voltage.
• CAT II - For local level, appliances, main wall outlets, portable equipment.
• The meter is designed to withstand the stated maximum voltages. For Safety
reasons,do not exceed the maximum stated voltage ranges.
• Do not operate the meter before the casing has been closed and screwed safely as
the terminals can carry voltage.
• Make sure the meter is set to the correct range before taking each measurement.
• Before using the meter, please inspect the case and test leads for damaged
insulation or exposed metal.
• Connect the red and black test lead to the correct measuring input jack properly.
• Do not input values over the maximum range of each measurement scale to avoid
damages of the meter.
• Do not turn the rotary function switch during Voltage and Current measurement,
otherwise the meter could be damaged.
• Make sure to use new fuses with proper rating. Do not use incorrect fuses.
• To avoid electric shock or damages, do not apply more than 1000V between the
COM terminals and earth ground
• Use caution when working with Voltages above 60V (DC) or 30Vrms (AC). These
Voltages pose shock hazard.
• Replace the battery as soon as the battery indicator icon "
low battery, the meter might produce false readings that can lead to electric shock
and personal injury.
• Turn off the meter once finished measuring. Take out the battery, when the meter
will not be used for long period.
• Do not operate the meter under adverse environmental conditions such as
excessive humidity.
• To avoid damage and dangerous operation, do not alter or change the circuit.
• To clean, periodically wipe the case with a damp cloth and mild detergent. Do not
use abrasives or solvents.
