Voltage Tester, Jellas Non Contact Voltage Detector Volt Pen, Electrical Tools Tester with LED Flashlight- 90V to 1000V Dual Range

Jellas Voltage Tester is a non-contact voltage tester with an integrated torch.Electricians, maintenance, service, safety personnel can quickly test for energized circuits and defective grounds on the factory floor, in the shop.

Manual:
Carry out a function test before use by using the tester on a known good circuit to ensure correct operation. The LED will illuminate and the buzzer will sound.
Press LED button to turn on tester ,with a drop of sound,green LED will light. Press the button again to open flashlight;when press one more, flashlight is off. Press for one second to turn off tester.
When detect voltage, tester tip sounds with red LED; when electric field becomes stronger, tester is with faster sound. Even the zero line and wire line are close, user can easy to distinguish by sound and light alarm.
Breakpoint detect: two sides of the breakpoint have different radiation intensity, the difference can make tester emit different frequency sound. With obvious sound difference, user can find the breakpoint location. (Prerequisite: the line with breakpoint must be located on wire line, test along the surface of the line.) 
When no electric field signal is detected, tester is with green LED, it will automatically turn off in 5 minutes. Tester is auto power off to save power, with low battery.
