Non-Contact Voltage Tester 12V/70V-1000V with Breakpoint Finder | Electrical Test Pen,Signal Percentage Indicator,Beep & Flashing LED Alarm,Multi-Wire Current Sensor,Live Wire Locator
Multi-wire Current Measurement: Mastfuyi voltage tester can detect both the neutral wire and the live wire. There is a groove at the tip of the device. To get an approximate current reading, firmly press the power cord against this groove and wrap it around evenly at least twice. Alternatively, you can measure by pressing the cord firmly against the groove and slowly sliding it back and forth. However, please note that this sliding method will result in a larger margin of error compared to wrapping the cord.
Non-Contact:Our Mastfuyi non-contact voltage tester is equipped with visual and audible alarms.Simply bring the tip of the NCV probe near a terminal, outlet, or power cord to measure AC voltage without physical contact.Note: Even when testing the same object, readings may vary depending on the distance.
High/Low Sensitivity: Switch between “High” and “Low” sensitivity modes according to your work requirements. “High” mode is suitable for detecting 12V–1000V, while “Low” mode is suitable for detecting 48V–1000V.
Optical & Audible Alarms:When high voltage is detected, the probe emits a red light accompanied by a high-pitched beep; when low voltage is detected, it displays a yellow light accompanied by a low-pitched beep.
Lightweight and Portable:This pocket-sized voltage tester pen features a pen-style clip, allowing it to be stored in a toolbox or clipped to clothing. Lightweight and easy to carry, it is a compact and portable tool suitable for a variety of work scenarios.
