• Audible circuit tester with digital display for accurate voltage reading
• Use on 12, 24 & 48V DC systems, found on many new vehicles
• LED illuminates when grounded
• Stainless steel testing probe
• Operation Temperature: 32-¦ - 122-¦F (0-¦ - 50-¦C)
• Measured Voltage: 0.3 - 60 VDC
• Testing Current: <10 mA
• Computer Safe (Low Draw)

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 GÇ£00.0GÇ? 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 GÇ£ErrGÇ?

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 GÇ£00.0GÇ? 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
