Instructions

Measuring Voltage:

1. The red clip is to be connected with the positive (+) polarity, and the black clip connected with the negative (-) polarity. The LED will display “00.0” when nothing is connected with the testing probe
2. When the test probe is connected to a positive voltage, the LED display will show a reading only if the voltage is greater than 0.3VDC. If the voltage is greater than 62VDC, the LED display will read “Err”

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

1. 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
