Inductive Measuring Mode
When the prob is placed close o the AC votage, the buzzer sounds and the voHage level will show on display. The
higher he voltage, the more rapid the buzzer sounds. Likewise, *HI"on the display Indcates high voliage,"U" indcates.

AC Voltage Detect
When the tester s on, press the button to enter AC voltage testing mode. The screen displays the AC voltage
reading when the test probe contacts an AC voltage source. This function can also detect AC voltage and
distinguish zero and live wires according to the voltage.
Continuity Detection O
When the tester is on, press the buton with th right han, and hold ane end of the uncharged wire with the
lefthand while contacting the other end o the wire with the test probe. I the wire is connected correctly, the
