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...?
