Adjustable Sensitivity?: Dual Range 12V-1000V / 48V-1000V-choose different range according to your needs
Different Voltage Test & Dual Range Testing - Distinguish the live and null wire through different frequency alarm sound; The default ac voltage measurement range is 48-1000V, it can also measure 12-1000V by adjusting the sensitivity. Which meets the need for selecting the most suitable sensitivity before testing on different occasions and different objects.
Non Contact Voltage Tester - It will flash and beep when the device close to AC voltage greater during the specified voltage range without touch the measured object, and also with the beep sound and LED to indicate to support enough safety measuring application
Safely Sound & Light Alarm - Voltage frequency can be distinguished by beep and LED indicator. It's loud enough to hear over moderate machine equipment noise. Small in size, easy to store in tool box or carry in your pocket
LED light & Low Voltage Indicator - The shining prompt of low voltage LED and alarm can warn you to replace the battery in time, while the white LED light allows operating even on dark environment; Auto power off after no operation for 5 mins to save energy
