AC Voltage Tester will send out multiple alarms through sound and light. When the High voltage is detected, the test probe will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency.
At the same time, the indicator light turns red or green, red means the high voltage and live wire are detected, green means the low voltage and null wire are detected.
Features: Switch measurement mode between high sensitivity range of 12V-1000V and a low sensitivity range of 48V-1000V is available. Quickly checks shorts or broken circuits in all types of electrical devices.
Non-contact detects the live/null line and reminds you of a beeping sound and LED light. With high definition LCD display and flashlight, values can be clearly viewed in low-light or secret areas. Convenient design for you to clip the tester to anywhere that is easy to reach, such as a collar, notebook, sleeve, etc.
