NOTICE:
When detect the same null wire, why sometimes the beep sound’s frequency and the number of the grids on the LCD is
different? If the live and null wire are too close, the tester pen will still beep quickly than normal when it detects null
wire, this is because the live wire is too close that cause the pen detect its strong voltage.
This also explains why sometimes all the sockets of outlet will beep at the same speed when detects the outlet.
When detect the live/null wires, better apart the two wires to a certain distant.
What is the default setting? and how to change the sensibility? The default setting is 48V-1000V. Simply short press the "S" button, then the button will lit,which is under 12V-1000V sensibility.

【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.
【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
【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
【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
