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 “ ” appears. With a

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.

• International Electrical Symbols:
