How to Use:
- Press and hold the power button to turn on.
- Short-press the H/L button to switch sensitivity modes — H for high sensitivity, L for low sensitivity.
- Short-press the light button to turn on the flashlight; long-press the light button to activate the indicator light.
Non-Contact AC Voltage Tester
Voltage Tester & Dual Sensitivity Mode (High / Low)?
Quickly check live wires, sockets, switches, and lights without touching any conductors. Simply bring the tip near a source – the tester alerts you instantly, making it the safest way to troubleshoot dead circuits.
Switch between two sensitivity levels as the job demands:
- High mode? detects 12V–1000V AC (ideal for standard household wiring).
- Low mode? detects 48V–1000V AC (helps pinpoint specific live wires in crowded junction boxes).
Break Detection
Principle of AC Wire Break Detection & Usage notes 1
This product detects the induced voltage strength around an AC power line to determine the approximate location of a break point. Therefore, it is very important to first confirm whether the wire carries AC current.
According to the physical principles of alternating current, AC can also induce voltage in nearby ungrounded metal objects — users should be aware of this during testing to avoid false readings.
Usage notes 2
Neutral and Live Wire Detection
When you need to identify which wire is the live (hot) wire, this product can be very helpful. First, it's important to understand that the device works by detecting the induced voltage strength around an AC wire. This means that even when testing the neutral wire, if the live wire is very close, it can still trigger the tester's buzzer — though the buzzing frequency will be noticeably lower.
A typical scenario is a wall socket, where the live and neutral wires are next to each other. When the tester is inserted into the live slot, the alarm sounds at a high frequency. When touching the neutral slot, the alarm is either gentle or silent, depending on the strength of the induced voltage from the live wire (i.e., the voltage level within the live wire).
