Adjustable Sensitivity & Dual Range Testing - You can adjust the sensitivity according to your needs (12-1000V AC or 48-1000V AC); Automatic Recognition of Voltage Intensity; the NVC sensor of probe can automatically identify the voltage and display it on the LCD screen.
High Definition LCD Screen and LED light - New style of LCD Display indication show 8 level of the voltage range (green light indicates low voltage; red light indicates high voltage which can be dangerous to body).
Buzzer Alarm - Distinguish the live and null wire through the different frequency of alarm sound. When it senses the voltage around, it start beeping, even though the tester pen hasn't touched the item. As voltage stronger, it beeps lounder.
