I am not an Electrical Engineer nor Electrician, however do have a degree in "General Engineering" from supposedly an "equivalent" to "Ivy League" Institution of Higher Education! I attempted to get another degree in Electrical Engineering after my "service" in the never ending "Global War On Terror" however due to the "awesome" US DVA and injuries sustained, etc... was not able to complete! That being said I have known for a very long time that "things" were not quite right with "utility" services in my "location" on the "eastern Shore" of Mobile Bay, Alabama. After reading "Electrical Troubleshooting Meters 101 For Commercial and Industrial Maintenance Personnel"- Kindle Edition by L.W. Brittian (Author) (at Amazon https://www.amazon.com/gp/product/B005NU61HS/ref=oh_aui_d_detailpage_o01_?ie=UTF8&psc=1 ) I decided to purchase this piece of equipment along with Ideal "SureTest Circuit Analyzer-Model Number 61-164" (at Amazon https://www.amazon.com/Ideal-Industries-61-164-SureTest-Analyzer/dp/B000E9ZCOG/ref=sr_1_1?ie=UTF8&qid=1519905167&sr=8-1&keywords=ideal+suretest+circuit+analyzer ) , which Mr. Brittian, discusses a "similar model" (understand model he discusses no longer in production IAW internet) in-depth in his book, above! Well, I received this device, and after reading instructions decided to try it out. I was in fact shocked and appalled at what I discovered!?!? (see attached photo's of a purchased from Amazon.com device "In-Action!") I did as per instruction's in manual and "attempted" to contact my "local" power company- really did not do much good, as far as I can tell yet (see photo's)????? Furthermore, IAW the "Quick Reference Sheet" that comes with device, under "Test #5: Line Impedance's", "IEEE states the ground impedance should be .25 (Ohms) or less for sensitive electronic equipment to operate properly!" (see attached presentation/photo's!) This, might very well explain, in large part, I have gone through more "electronic" devices in this area, since my arrival over a decade ago, than anywhere in world, to include combat the US Military sent me! Furthermore, IAW "Code Check Electrical: An Illustrated Guide to Wiring a Safe House" - Spiral-bound – June 24, 2014 by Redwood Kardon (Author), Douglas Hansen (Author), Paddy Morrissey (Illustrator) (at Amazon https://www.amazon.com/gp/product/1621137783/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1) a lot of things this area are simply not correct, external to my and othr's residence's, if this work is in fact correct on whole host of topics. (see attached photos/ presentation) Additionally, I purchased "Sperry Instruments GFI6302 GFCI Outlet / Receptacle Tester, Standard 120V AC Outlets, 7 Visual Indication / Wiring Legend, Home & Professional Use, Yellow & Black " at Amazon https://www.amazon.com/gp/product/B000RUL2UU/ref=oh_aui_detailpage_o02_s01?ie=UTF8&psc=1 ! This is a good indicator, to see if outlets need further testing with other devices such as this one! Also, handy, and highly user friendly is "Wiring 1-2-3 (Home Depot ... 1-2-3) Hardcover" – January 15, 2001 by Home Depot Books (Author), Catherine Staub (Editor) (at Amazon https://www.amazon.com/gp/product/069621184X/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1) which explains a whole host of things like wire gauge etc.... For those interested in becoming electrical engineer's I would recommend "NOW 2 kNOW Electro-Magnetic Fields"- Paperback – September 22, 2012 by Dr. T G D'Alberto (Author) (at Amazon https://www.amazon.com/gp/product/0988205416/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1) as it shows the level of "mathematics" one must achieve proficiency in to "attain" this status or degree! As matter of fact, while attempting this degree myself, my professor's told me most Electrical Engineer's are in fact "accomplished" mathematicians in their own right! However, this requires "quite" a very good long/ short-term and clear "working" memory! I would also recommend, Amazon.com- "Everything Electrical: How To Test Relays And Involved Circuits"- (Revised Edition 5/10/2017) Kindle Edition by Vincent Keler (Author) (at Amazon https://www.amazon.com/Everything-Electrical-Involved-Circuits-Revised-ebook/dp/B00T75WDFO?_encoding=UTF8&redirect=true&ref_=ku_mi_rw_edp ) to not only get "quick" grasp of concepts but as supplement to this Sperry device.... for follow on "investigation" if one so desires.... Anyway, I would highly recommend this SPERRY "circuit analyzer" to anyone purchasing a new or "older" home to test the "outlet's", very quickly, as is highly recommended prior to either purchasing or "accepting" delivery of a "newly built" home....! And, perhaps a follow-up with the IDEAL SureTest Circuit Analyzer!!! This way, hopefully one will not be "raising" their fist in the air- which is a symbol of "quite" a bit, like a statue in Belgium representing "Flemish" struggle independence...?

I used this while looking for a house to purchase and this has been extremely handy to have, especially when I was shown older homes. I was at a showing this past weekend and the outlets were testing at 3 different kinds of bad. It's great at taking away the surprise in terms of the electrical and the amount of work that will need to be done in an early 20th century house. This tester may help you negotiate a lower price with a home like I mentioned. Great little product to carry around in your pocket.

I really do like this device, now that I've figured it out, i know what to expect of it. I took off a star for the lack of clarification on the device about odd readings (readings that are not described) So, I've seen some reviews about light bleeding from one light to another, giving a somewhat confusing reading. This isn't light just bleeding through plastic, the bulbs in there are indeed lighting up but very faintly. I rewired a bunch of outlets, and in the process learned a few things about this device: -It's made very nice, feels good -It Cannot diagnose every problem -The chart does Not describe every possible indication you may see -It Does let you know overall if something is wrong. So, what i mean is that on the device it shows you a list of all possible light configurations. However, two situations are notably missing: all lights on, lights partially on. I've encountered situations where all lights illuminate, but the chart doesn't show this situation. I've also seen variations of lights being on, but only slightly. This is where i think some folks thought it was due to one bright light bleeding into the next light making it seem like it might be on, but it's really an indicator of some other issue. Either way, unless you get two solid orange lights, something isn't right. You might think that they would mention this in the manual. Nope. Nothing. That's really unacceptable for a device intended for electrical work. Overall, this device indicates two things reliably: Everything is OK, or something is Wrong. If you get anything but two solid orange lights, something to some extent is wrong. Even if i get solid light indications, i check everything again with a multimeter. You can get decent ones for around $25, and they will tell you exactly what's going on with the outlet. Why not just get a multimeter? That's certainly an option, but my preference is to have the little tester for blanket sweep checks of everything, marking the bad outlets, then going back and checking the bad ones with the multimeter to see exactly what's going on. Bonus round: Testing an outlet with a multimeter is easy: set it to voltage reading and: red probe to the (hot)small outlet slit, black to the (neutral)big slit. should be 120(ish) volts, then do red to small slit, black to ground (bottom outlet hole), should also be 120v. Then one probe to big slit, the other to ground, should be zero or near zero reading.

I use this at work as an electrician and have found the sensitivity adjustment very useful - it will react at quite a distance with new batteries, which are lasting well, and can be set to pick up lower voltages/closer to cable to identify live conductors I generally don't trust cheap electrical testers but this one has so far proved to be very good. It has limitations in regard to clarity of the voltage it picks up, it won't tell you what the voltage is - just that there is voltage present. Otherwise - I was so impressed I bought another for a work mate ....

Se aprecia de buena calidad. Hice pruebas y ha trabajado satisfactoriamente

as described; great value and low cost. Used daily. Would buy again.

This is a must have tool for any DIY guy doing electrical work around the home. Works great and save time tracing live wires. You can regulate it to check from 14 volts DC to 600 Volts AC. The seller was fast in shipping the product and was received the same way as advertise by the seller. I have no hesitation in recommending this seller to anyone who may be thinking of purchasing this item.

I have a couple of these testers. Easily check if an outlet is wired correctly. I used it to find an open ground that was tripping my gfi. The Klein one works well, but this is a much better design. The construction is much more solid, with rubberized side grips, by the legend that identifies the lights is printed on both sides so you can see it regardless of the plug orientation.
