Continuity Testing:

1. The red clip is to be connected with the positive (+) polarity, and the black clip is connected with the negative (-) polarity. The LED will display “00.0” when nothing is connected with the testing probe
2. Connect the extension cable with the black clip or the negative (-) polarity
3. Connect the opposite clip of the extension cable with the opposing end of the testing target. If the current flows, a green LED indicator will display with an audible tone
