• 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 Vac rms, 42 Vac peak, or

60 Vdc. These voltages pose electrical shock hazards.

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

testing resistance, continuity and diode.

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

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

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

• If the meter is used in a manner not specified in the users manual, the

protection provided by the equipment may be impaired.

• To avoid injury, when the "battery low" indicator is present in the display,

the product should NOT be used. A false measurement may occur. The

battery should be replaced immediately.

MAKING MEASUREMENT

X�

1. Use the proper function and range for measurements.

2. To avoid possible electrical shock, personal injury or damages to the Meter,

disconnect circuit power and discharge all high-voltage capacitors before

testing resistance, continuity and diode.

3. Connecting test leads:

• Connect the common (black) test lead to the circuit before connecting the

live lead;

• After measurement, remove live lead before removing the common

(black) test lead from the circuit

4. Over-range indication: "1", "-1", or maximum display reading.
