## Overview

The Martindale NC4 Dual Sensitivity Voltage Tester offers professional-grade non-contact AC voltage detection from 12V to 1000V with dual sensitivity modes. Featuring audible and visual alerts via a bright red LED tip and buzzer, an extended probe for hard-to-reach areas, and an integrated LED torch for low-light conditions, it’s designed for precision and convenience. Compact and lightweight with smart battery-saving auto power-off, the NC4 is a reliable essential for electricians and DIY pros alike.

## Description

From the manufacturer Martindale NC4 Dual Sensitivity Non-contact Voltage Tester The NC4 voltage tester has two sensitivity ranges for accurately detecting the presence of AC voltages. The first will detect voltages between 50V and 1000V and the second will indicate voltages between 12V and 1000V. Sensitivity can be set according to the application and when in high sensitivity mode the LED pulse double flashes. The extended probe tip gives improved access and easier identification of live wiring. It indicates voltage by illuminating the clear tip section with a bright red LED and sounding a buzzer. The pen-shaped design with clip makes it ideal for carrying in a pocket or tool belt when working at height or in difficult to access locations. There is a useful LED torch which illuminates the area directly in front of the tip. Auto power off and a recessed on button ensure a long battery lifetime and the NC4 functionality also includes low battery indication. The NC4 replaces the Martindale VT4. Two ranges 12V – 1000V and 50V – 1000V AC Audible and visual indication Extended probe for easy access Clear tip for high visibility indication LED torch for use in low light LED pulse and auto power off Built for safety (CAT VI 1000V) Visual indication Audible indication Auto LED torch for use in low light

Review: NC4 not too sensitive, just about right. - I was looking at getting the Fluke 2AC/90-1000V but found that it does not have an audible alert and the LED isn't great in bright light. I looked at the 1AC-II which has an audible alert, however the UK version is only 200-1000V. Ignore UK suppliers advertising the 90-1000V, you'll receive the UK 200-1000V model. I wanted to have a non-contact tester that would indicate lower voltages such as 110V. Having recently bought the Martindale VT12 Voltage Tester and found it to be very good (see my review) I took a punt on the Martindale NC4 as a companion device. The NC4 has two sensitivity ranges 12-1000V AC (not DC) and 50-1000V AC with a nice audible alert and flashing red LED when it detects my 240V domestic supply (I don't have anything lower in AC to test). It also has a handy LED torch function. When you first switch on the NC4 the bright red LED flashes once a second to indicate that it is in the 50-1000V range. Briefly pressing the button again switches to the 12-1000V range and the red LED flashes twice in one second. Turn off the NC4 by pressing the green button for 2 seconds or it will eventfully auto-power off. I did a 240V test of how well it works where there are three wires in close proximity. I cut the end off a cable exposing the Live/Neutral/Earth to a length as you would when fitting a UK plug. I then plugged the other end into 240V so making one of the three exposed wires live with the other two dead cables close to the Live. In the 50-1000V range the NC4 probe had to be approximately within 3mm of Live for it to alert, it did not alert when placed near the other cables even though they are close to the Live. In tight spaces it is unlikely that you will get false positives from cables that are not live when they are close to a Live. That is an excellent result, I've read reviews where these devices are far too sensitive and pick up so-called "live" cables when in fact they are picking up the Live from one close-by. I much prefer to be almost touching the Live cable, the probe is long and suited for this very purpose. In the 12-1000V range you merely have to be within 50mm of the cable for it to detect Live, handy for checking thicker cables and wall/light sockets (it isn't sensitive enough to detect cables within walls). You'd also use this when waving it around to find a Live cable and then you'd switch to 50-1000V to focus in onto the individual Live cable. As with any device there is the odd gotcha with these things that can trip you up: When using a non-contact tester it is important to know that when testing cables you should move the probe all around the circumference and up and down the length of the cable as the Earth cable could be blocking the detection of the Live in a twisted core. You should of course test the device on a known Live before use (and after use if it didn't find anything as it could be faulty!). As with any device of this nature (like neon screwdrivers) you should NEVER use it to test for dead. These devices are not reliable enough to put your life at risk, in a tight space these devices can easily be fooled if the Earth wire is blocking the Live wire. Use with caution and know the limitations of your kit. If you must rely on a device for testing for dead then a Martindale VT12 is absolutely what you should be using. I can not stress the importance of using a VT12 to test for dead and not one of these non-contact devices, or you might be dead yourself!

## Questions & Answers

**Q: Will this work with 24v ac fairy light, i bought few which doesn't work and too sensitive for low voltage.**
A: Yes it will

**Q: can it detect live wires behind plaster board?**
A: It all depends on how far the wires are located behind the plasterboard - however there is a 50/50 chance of this type of detector being able to detect live wires behind plasterboard - try searching for a Draper 13818 Combined Metal Voltage and Stud Detector.
