Review: An essential bit of protection - An excellent and reliable bit of kit. Simple to use and sold at a great price
Review: Works really well! - Brought this to check any live wires before doing some rewiring to be safe and so far so good! Good quality, instructions are very clear and it’s a bonus to have the sound along with it.

## Features

- Non Contact: Just place the NCV tip near a terminal strip, outlet, or supply cord. When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Tests. Handy circuit tester for electricians, and homeowners.
- Safety First: It will send out multiple alarms through sound and light. When the voltage is detected, the tip 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 screen will be red or green, red means the high voltage and live wire are detected, and green means the low voltage and null wire are detected.
- Dual Range: Only detects AC voltage (12-1000V AC / 70-1000V AC) for more sensitive and flexible measurements. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring, etc; The NCV sensor automatically recognizes the voltage and displays it on the bar graph.
- Security Level: IEC-rated CAT III 1000V, Meets CE requirements; The electrical tester is safely double-insulated. High Voltage Alert to warn you of voltage above 70V, the screen turn red, and the electric shock warning symbol is displayed on the screen.

## Questions & Answers

**Q: Will this work through drywall?**
A: I just tried a few walls near light switches where I knew there was elec wires with switches on. The meter would register about "1 line high" near the wires BUT it would also cause the meter to blink the same on places on the wall where there was absolutely no elec wires! I did the test both using the regular setting and also the Supper Sensitive setting. So MAYBE it MIGHT give you some idea where the wires are, but doubtful since there are to many false readings to be sure. That said, this meter works great if you are taking readings without sheetrock blocking it.

**Q: would you recommend this over other models and why?   what do you NOT like about it?  how accurate is it?**
A: I like that it is louder than others, equally easy to use, and the price was good

**Q: I believe a wire that goes from my speaker passenger side rear door is dead, would I be able to use this to test the wire to see if there's power?**
A: You. Will need 12v tester

**Q: Do i manually switch from "lo" to "hi"? pressing the green "sensitivity" button on mine does not switch to "hi".**
A: Mine does not even turn on.

I bought it as a spare. I had two £20 testers and one stopped working. It is good for the price but not as robust as my Fluke tester
