Bside AVD06X Non Contact Voltage Tester Pen Electric AC Power Detector 12-1000V Dual Mode Freely Adjustable Sensitivity Breakpoint Locator with 8 LED Indicators and Flashlight

What is the development history of voltage detector Series 1 Contact voltage detector Series 2 Noncontact sensitivity not adjustable Series 3 Noncontact sensitivity can only be adjusted to 2 values Series 4 Noncontact sensitivity can only be adjusted to 3 values Series 5 Noncontact dual mode Automanual freely adjustable sensitivity smart voltage strength detection Series 1 to 4 are single mode voltage detector and the series 5 is dual mode voltage detector Why is the dual mode voltage detector better than the single mode voltage detector The dual mode voltage detector has Automanual mode for selection according to your needs which can applied to more applications The single mode voltage detector has only one detection mode and the application is greatly limited How does our AVD06 voltage detector smart indicate the detected voltage strength Our voltage detector has 8 LED indicators in 3 colors It can smart judge the detected voltage strength by automatically light different color quantity LED indicators In manual mode Low voltage 1248V 2 Green LED indicators light up slow alarm sounds Medium voltage 4890V 2 Green 3 Yellow LED indicators light up fast alarm sounds High voltage 901000V 8 LED indicators light up much faster alarm sounds In Auto mode Low voltage 4890V 2 Green LED indicators light up slow alarm sounds Medium voltage 90130V 2 Green 3 Yellow LED indicators light up fast alarm sounds High voltage 1301000V 8 LED indicators light up much fast alarm sounds Package Includes 1 NonContact Voltage Tester 1 User Manual Note The batteries 1 9V are not included in the package due to Aviation Security Check
