To avoid possible electric shock or personal injury, and to avoid possible damage to

the Meter or to the equipment under test, follow these guidelines:

• Before using the Meter inspect the case. Do not use the Meter if it is damaged.

Look for cracks or missing plastic. Pay particular attention to the insulation

around the connectors.

• Inspect the test leads for damaged insulation or exposed metal. Check the test

leads for continuity. Replace damaged test leads before using the Meter.

• Verify the Meter's operation by measuring a known voltage. Do not use the Meter

if it operates abnormally. Protection may be impaired. When in doubt, have the

Meter serviced.

• Do not apply more than the rated voltage, as marked on the Meter, between the

terminals or between any terminal and earth ground.

• Use caution when working with voltages above 30 V ac rms, 42 V ac peak, or 60 V

dc. These voltages pose a shock hazard.

• Use the proper terminals, function, and range for your measurements.

• Do not operate the Meter around explosive gas, vapor, or dust.

• When using the probes, keep your fingers behind the finger guards.

• 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.

• Disconnect circuit power and discharge all high-voltage capacitors before testing

resistance, continuity, diodes, or capacitance.

• Before measuring current, check the Meter's fuses (see "Testing Fuses") and

turn OFF power to the circuit before connecting the Meter to the circuit.

• Do not operate the Meter with the case (or part of the case) removed.

• Use only a single 9 V battery, properly installed in the battery receptacle, to

power the Meter.

• Replace the battery as soon as the battery indicator (M) appears. With a low

battery, the Meter might produce false readings that can lead to electric shock

and personal injury,

• Remove test leads from the Meter before opening the Meter case.

•

When servicing the Meter, use only specified replacement parts.
