. Press SELECT button momentarily to select Continuity function that is

convenient for checking wiring connections and operation of switches. A continuous
beep tone indicates a complete wire.

CAUTION
Using resistance and continuity function in a live circuit will produce false results and
may damage the instrument. In many cases the suspected component must be
disconnected from the circuit to obtain an accurate reading
