• 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 guard
