Rated 1 out of 5 by from Does not work I Just recibes the voltalert. But it doesn't work correctly. I live in a city with an altitude above 3500m. Is it a reason for not working?

Rated 2 out of 5 by from 1 Flaw I just got my 2AC/90-1000V unit. I have a Fluke 787 ProcessMeter provinding me loop-current (24VDC) to my PLC anlog input module. The pen tip stays lit when it makes contact to the meter-leads. (??) When checking outlets and power cords, it seems to work right. So, why does it stay lit with 24VDC loop power?

Rated 5 out of 5 by from Great and cool tool for every family! I've owned and used this product for a few years and loved it very much. It has helped me a lot to test my house wall plugs and power lines to check whether there is power or not. It's so easy to use and always gives me a peace of mind before I touch or fix the plugs or lines. I have also used this tool to diagnose broken Christmas lights to pin-point which light is burned out, especially when the light decoration is very long. Highly recommend to anyone who needs to deal with any power issue around one's house!

Rated 4 out of 5 by from only volt alert i would use I am a industrial maintenance electrician, and I have had several voltage detectors. This is what I use everyday. If you need one, I highly recommend these.

Rated 5 out of 5 by from It Just Works I've been carrying this 2AC tester daily instead of the classic 1AC-A that I normally carry. Not needing to "turn on" the tester has been very convenient and the lens flashing red upon movement confirms there is battery power remaining.

Rated 5 out of 5 by from best non contract voltage tester on the market I have used the 2-AC non contact voltage tester for over ten years. Even after repeated drops and bumps they keep on working. I have never had one that didn't detect voltage when there was voltage in the circuit. Sometimes the tester shows voltage when there is none but that just means I need to double check with my meter- which happens to be the fluke T+Pro electrical tester. It's a tough pair to beat.

Rated 4 out of 5 by from Good Factory Tool We use this in our production line to test high voltage equipment. Small, lightweight and clips into your pocket so it does not fall out. Buy it.

Rated 4 out of 5 by from Easy to use As an industrial electrician the Fluke 2AC Voltalert has helped out immensely. Easy to use. Accurate and tough are a few of the adjectives to describe it!

Rated 5 out of 5 by from perfect for a sure and safe circuit We sell these all the time to our contractors. They like the product for the value and the performance. It is a standard for most electricians. I have one at home too. Very useful tool.

Rated 1 out of 5 by from Poor 220v response. No beep. Description reads audible/beep, but no sound at all when near power. Also, does not properly detect 220v. Just a single very quick LED flash. Unusable tester.

Rated 4 out of 5 by from Good but not 5 stars! The directions for use that come with this instrument are flawed and the most important directions are not even included. The tip of this detector should be inserted into the SHORT (rectangular) slot of the 3-hole receptacle. If it is inserted into the short slot (which is the HOT slot), then it will shine bright red if the receptacle is live, and the light will stay on until you pull the tip out. If you insert the tip into either the round/ground hole or the long slot (which is not hot), the only way this detector works is when you pull OUT the tip, and then you will see just a red flash. By the way, the round ground "slot" and the short, upper slot are tied together internally, and neither is hot. The other reason I can't give this product five stars, is that the tip appears to be likely to break off with repeated use, so you have to be careful and insert it and withdraw it without bending it side to side.

Rated 5 out of 5 by from Indespensible This is the perfect device to troubleshoot bad strings of Christmas bulbs!! Easily identifies the last live bulb in the string so you can isolate the failure. Worth its weight in gold at this time of year, and keeps me from losing my mind.....!!!!

Rated 1 out of 5 by from Light Undependable The light comes on when moving the tip away from anything whether electricity is present or not. I could not find a way to contact Customer Service via web or email and I choose not to waste time in Fluke's telephone system waiting for assistance.
