Product overview: Fluke 2AC Non-Contact Voltage Tester

Always on for faster, safer voltage testing

The Fluke 2AC is the latest addition to the VoltAlert™ AC non-contact voltage tester family. It is designed to be pocket-sized and easy to use. The tip of the pocket-sized tester will glow red when within close proximity of an outlet, terminal strip, or power cord where voltage is present. The 2 AC is always on, with a battery check function to make sure the tester is working properly. *

Your first-choice tool for go/no-go testing

The 2AC tests for energized circuits and defective grounds, whether it's for an electrician on the factory floor or the do-it-yourselfer around the house.

CAT IV 1000 V overvoltage rated product for best in class user protection
Suitable for a wide range of residential, commercial and industrial needs
Fluke ruggedness and reliability with a two-year warranty

* Use of Battery Check function is optional and for convenience only, it is not intended as a substitute for checking the unit on a known live source before and after use.

Rated 5 out of 5 by Sparkone from Solid tester. Always on and ready to fast test. Rhis tester is simply the best for me. I work in noisy generation environment and without this is not possible to identify power presence. Its suitable for industrial use as all you need is speed and the light the buzzer won't be much use for me! as machines are too loud you ate at home then you may need a volt stick that sounds. I tried kewtech but it failed so a reliable fluke is what you need at busy times! It could be a little longer (taller) becouse the voltages are too high at times but you can use it with an extension pole so easy of use then nakes to 4 stars not 5 !

Rated 5 out of 5 by pewpew from Very good I personally prefer the no beep and the beep is useless where I work anyways. Just make sure you test your tester before testing a wire to ensure it is functional. The only false positive I've gotten was from induced voltage, and no false negatives unlike the Milwaukee one I've used. Beep is subjective and I like not having it!

Rated 1 out of 5 by Laser from DANGEROUS No Audible alert! Twice I've almost been electrocuted because I couldn't see the light at the tip, in the sun. I don't understand why there is no audible setting? Very dangerous for an electrician or do-it-yourselfer!

Rated 1 out of 5 by Tony13 from Brand New Inoperarative I purchased the Fluke 1AC II Non-contact 1000 Amp 1000-Volt LED Voltage Tester It was on special and I paid $36 plus the tax. I took it out of the package tested it and it work great. I store it in my tool box. Close to a year my lights when out at home and I wentt to go use it. It did not work ! I purchase new AAA betteries and when I put them in a red light comes on with a loud screaming beep and it will not turn off !!! I paid cash for it . A waste of money and truly disappointed!!!

Fluke Voltage Detector Pen: 2AC Non-Contact Voltage Tester (2024)

FAQs

Do non-contact voltage testers work? ›

Non-contact voltage testers work by sensing a very small amount of current that is capacitively coupled from the live circuit to the tester and back to ground. Non-contact voltage testers light up when they detect this current without needing to make direct contact.

Discover More Details ›

What is the disadvantage of a non-contact voltage tester? ›

One risk is that the detector is broken, and does not indicate a live wire. The safe way to use one is to have an actual live wire and to check that the detector detects it every time you use the detector on an unknown wire.

How do you use a voltage tester to see if a wire is live? ›

Assuming you are talking about AC wiring, put the DVM (digital volt meter) on the AC Volts scale. Connect one lead of the DVM to ground (box frame for example). Connect the other probe to the wire. It should show either line voltage (live wire) or a very low voltage or even zero - the neutral wire.

How to read a voltage tester pen? ›

Move the Volt Stick close to the object you need to test and be careful not to touch any exposed metal work with your hand or any other part of your body. If there is an AC Voltage present, then the tip of the Volt Stick will illuminate and, if the Volt Stick has an Audible Indicator, it will sound.

Discover More ›

Is voltage tester pen safe? ›

The voltage testing pen is reasonably safe if you use it properly. Number 1: be sure to touch only the insulated handle. Number 2: keep your other hand in your pocket so it can't make contact with anything (this avoids the chance of any current accidentally going through your body if the insulation should fail).

Show Me More ›

What does a voltage detector pen do? ›

The Volt Stick will indicate the presence of a Voltage while the user is holding it, as there is a potential difference but it will turn off when they remove their hand as there is no ground reference and they are at the same potential.

How to check if a tester is working or not? ›

Confirm that the circuit tester is working by carefully touching the hot wire with one lead and a neutral wire with the other. The tester will light if it's working. Touch the hot wire with one lead and the ground wire with the other (Photo 1). If the tester lights, the ground wire is good and you can use it.

Find Out More ›

What does the red light on a voltage tester mean? ›

Non-contact voltage testers usually feature both a visual light and an audible signal. A non-continuous light, no light, or even a green light with no beeping means voltage is not present. A red light with a continuous tone means there is voltage present.

What is the difference between fluke 1ac and 2ac? ›

A: The 2ac is the newer model with an "always on" function. It has a button that is used only to ensure that it still has battery power. The 1ac is the older one that can be turned on or off. They both test for voltage presence the same way, but the 1ac has an audible alert function which the 2ac does not have.

How do you test an outlet with a non-contact voltage tester? ›

Turn the voltage tester on. Test the voltage tester on a working outlet by inserting the tip into the "hot" side of the outlet. Return to the device or wire that you want to test. Hover the tip of the voltage tester about 1-inch from the wire and the tester will chirp and flash if a current is detected.

Get More Info ›

Do non-contact voltage testers work through walls? ›

Yes. The instrument has two detection levels, one for low voltage and one for house voltage and above. If you want to check for wires behind walls, switch the instrument to low voltage detection mode. It will then me sensitive enough to detect house voltage in lines behind walls.

How do you use a non-contact voltage tester to find hot wire? ›

Non-contact Voltage Testers:

By holding them near an outlet or wire, you can determine if there is an electrical current. They emit an audible alert to indicate live voltage. Pros: Quick, easy to use, and suitable for homeowners. Cons: May give phantom readings, necessitating further testing.
