WARNING: Read before using

• To avoid possible electrical shock or personal injury, follow these

instructions and use the Meter only as specified in this manual.

• Do not use the Meter or test leads if they appear damaged, or if the

Meter is not operating properly. If in doubt, have the Meter serviced.

• Always use the proper function and range for measurements.

• Before rotating the function range selection switch, disconnect test

probe from circuit under test.

• Verify the Meter’s operation by measuring on a known voltage source.

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

the test probe or between any test probe and earth ground.

• Use the Meter with caution for voltages above 30 V ac rms, 42 V ac peak,

or 60 Vdc. These voltages pose electrical shock hazards.

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

testing resistance.

• Do not use the Meter around explosive gas or vapor.

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