Feature: *AC voltage display and buzzer alarm: When measuring AC voltage, the tip of the pen touches the live wire, and the hand touches the touch electrode on the side. When measuring the voltage, the human body simulates the earth and has deviations that vary from person to person. *Zero Live Wire Identification, fast and highly sensitive discrimination: (Zero Live Wire Identification) Touch the touch pole with your hand, insert the pen tip metal into the hole, the red screen and rapidly beeping sound are the Live Wire; the green screen displays the voltage 0V, which is the Neutral Wire *Intelligent non-contact, NCV power induction: (non-contact induction) When the nearby AC voltage is detected, the screen index rises from LOW to HiS, and the closer the power source is, the more rapid the beeping alarm sounds. *Line breakpoint detection, test pen function: (Measure line breakpoints) Detect the screen index along the line to HiS and beep sharply to indicate that the line is smooth and good, and when the line is disconnected, the index is LOW *LED lighting function to illuminate the front for you: (flashlight) No matter what the environment, it can illuminate clearly to eliminate the risk of electric shock and assist in night measurement work *Double-color digital display color screen, real-time prompt: (Double-color screen) alarm sound prompt, two-color distinction to distinguish the zero live line, quick identification Specification: Product model: VD807 Measuring range: 12-300V Weight: 33g Alarm mode: sound and light alarm Frequency: 50Hz/60Hz Batteries used: 2 AAA size 7 batteries (batteries not included) Flashlight: LED lighting Automatic shutdown:√ Identification of zero live wire: Touch the touch pole with your hand and touch it with the tip of a pen. The high voltage is the live wire, and the low voltage is the neutral wire.
