KAIWEETS Voltage AC Adjustable Screwdriver with LED Percentage Voltage Detection Tester, 12-1000V / 70-1000V AC, Sensitivity, Pen-Shaped Flashlight,

---------------------------------------------------------------------- Non-Contact Voltage Tester: Includes an NCV probe for AC voltage; the tip glows red and the pen beeps to indicate voltage is present. The live wire detector automatically detects live or neutral wires. Ideal for testing breakpoints. A convenient circuit tester for electricians and homeowners. [Safety First] Multiple alarms with sound and light. When voltage is detected, the tip will glow red and a beep will sound. The higher the detected voltage or the closer it is to a voltage source, the higher the frequency of the beep and the larger the percentage value. At the same time, the screen will turn red or green. Red indicates high voltage and live wires, and green indicates low voltage and null wires. Dual Range: Detects both standard and low voltages (12-1000V AC / 70-1000V AC), providing greater sensitivity and flexibility. Press the S button to adjust the sensitivity and use the low range for doorbells, thermostats, irrigation wiring, and more. The NCV sensor automatically detects voltage and displays it on a bar graph. The percentage value provides a more intuitive indication of voltage signal strength. [Security Level] Compliant with IEC standards CAT III 1000V, CAT IV 600V, and CE standards. High voltage warning function turns the screen red and displays a safety symbol if the voltage exceeds 90V. Compact Design: This LED flashlight provides bright light even in dimly lit areas. It indicates low battery when the battery voltage drops below 2.5V and automatically shuts off after 5 minutes if no operation or signal is detected. Its pocket-sized design and pen hook allow you to carry it in your shirt pocket. We offer a 36-month warranty. Checking for AC voltage: It has multiple alarms with sound and light. When voltage is detected, the tip will light up red and a beep will sound. The higher the detected voltage or the closer it is to a voltage source, the higher the beep frequency will be. At the same time, the screen will turn red or green. Red indicates high voltage and live wires, and green indicates low voltage and null wires. Technical Specifications Voltage: AC 12~1000V, 50/60Hz Operating temperature: 0~40℃ Storage temperature: -10~50℃ Humidity: ≤95% Operating altitude: ≤2000m Safety Level: CE, CAT III 1000V, CAT IV 600V Battery: 2 x 1.5V AAA Note 1. Separate the individual wires as far as possible and read the signal. 2. Identify the neutral and live wires by the strength of the signal they detect. Live wires will detect a stronger signal, while neutral wires will detect a weaker signal.
