Instruction Sheet
WRead First: Safety Information

Never use the meter if the meter or test leads look damaged.

Be sure the test leads and switch are in the correct position for the desired measurement.

Never measure resistance in a circuit when power is applied.

Never touch the probes to a voltage source when the test leads are plugged into the 10 A or 300 mA input jack.

Never apply more than the rated voltage between any input jack and earth ground.

Be careful when working with voltages above 60 V dc or 30 V ac rms. Such voltages pose a shock hazard.

Keep your fingers behind the finger guards on the test probes when making measurements.

WWarning

To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator (M) appears.
