Sperry Instruments VD6505 Adjustable Non-Contact Voltage Sensor, 12-1000 V AC

Works perfectly, I need to confirm that my generator has an open ground. Used a bonded neutral and ground plug and reconfirmed with this tool that my grounded was bonded. Works perfectly and easy to use. Very well built safe to use and great visual confirmation lights.

Works great

Arrived fast and works perfect.

Works great

Nice tester to have for shop or home use, can't be easier to use!

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...?

Received items as described and in good condition. Also Received items quickly and very well packaged for shipping. Item works as described.

I've used it for several jobs and haven't even started my major wiring projects.Wanted to install a strong, reliable grab bar in my tub/shower exactly where I wanted it. Didn't want to be limited by the location of the wall studs. Before cutting out the sheetrock in the next room so I could add bracing between the studs I had to 1) locate the wiring precisely so I didn't cut it and 2) make sure it was dead while I was cutting.The sensitivity dial helped me pinpoint the location and route of the wiring. To start, I set it sensitive enough so that I could detect live wiring behind the sheetrock from about a foot away. I continued to dial the sensitivity back so that I had to be within an inch or two of the wiring for the sensor to respond (with a red blinking light and loud chirping sound). Then by moving the sensor along the wall, I could very precisely trace the run of the wiring, marking it with blue painter's tape.Before cutting into the sheetrock I flipped off what I was fairly sure was the correct breaker. To make sure, I dialed up the sensitivity of the sensor and swept it all over the wall where my painter's tape was. No response from the sensor indicated that I did flip the correct breaker, so it was safe to cut into the sheetrock. (In this situation you can hold the sensor near a lamp to make certain it will respond to current.)Silliest use I've made of the sensor was to make sure my crockpot was on. I'm going to upgrade my kitchen circuits. In the meantime the few kitchen receptacles are on one circuit, the electric range is on it's own. The range has a standard "convenience" outlet for temporarily plugging in an appliance, but it's old and "iffy". I started the crockpot on the regular kitchen circuit but had to move it and plug it into the range's convenience outlet. The crockpot doesn't have a power light, so I wasn't sure it was getting electricity. Maybe the plug needed a jiggle? Got my Sperry adjustable volt sensor out and sure enough, there was power in the crockpot power cord. Dinner was saved.The adjustability is what makes this so versatile. I've fiddled with the sensitivity dial and gotten it so that I could tell the hot from the neutral side of the power cord on a table fan. Touch the sensor to one side of the cord, no response. Touch it to the other side, flashing and chirping. Take a close look at the cord, and the no-response side has the telltale "neutral" ridge.It's a well-made and useful tool. Could save your life, could save your wiring. Could save your dinner.
