Yes indeed! Hence my suggestion in post #676 - To wit:
While that indeed describes a single-ended arrangement - the images in question relate to a (prospective) construction article featuring a balanced EHT indicator (applicable to floating EHT sources).
One caveat Re: use of DMM input impedance (Spec. resistance) as 'part' of the divider --- Some instruments vary said impedance during 'auto-ranging'!
-- Hence manual range selection prior to application of EHT to the divider is essential -- FWIW my suggestion/implementation of a d'Arsonval unit is merely by way of making the instrument as 'bullet proof' as reasonably possible -- In the 'EHT game' one needs all the breaks they can get!When I worked in the UCLA plasma lab, we used these guys a lot:A reliable source for EHT resistors of that form-factor would be truly grand!

Congratulations! You are quite literally the first person I've encountered in possession of that single, sorry, fact!
--- 'Tho I've met a few who "jus' can't understand" why their DMM's 'permanently loose their minds' following use with an HV probeNo need!
-- Therein lies the 'beauty' of the 'balanced' arrangement! - Inasmuch as the movement/metallic cabinet is at ground potential (within 1kΩ [worst case ground referenced EMF=100mV] Re: the underground movement terminal) - there's neither corona nor arcing to cause inaccurate operation nor liability to arc-flash injury to ruin one's day -- Again, the instrument is intended for measurement of floating (i.e. non-ground referenced) DC suppliesI find that certain ostensibly "10MΩ Zin" auto-ranging DMMs present a DC resistance of Ca. 55MΩ on their 'millivolt ranges' - and, most annoyingly, on all ranges following auto power-down!
Aye! -- And with a the selfsame 'reliability' as Greed, Gravity, Death and Taxes
Those look rather like 'focus divider' resistors? -- I'll wager there are a few of those "kicking 'round" shops having 'dead stock' in the desirable LOPTs --- Many thanks!
Good deal!!!
-- I'll check that out -- Thanks again!HP I say eV has to go cuz anyone who doesn't even know that has totally come to the wrong place
! Also PCB expansion for dielectric oil is ok but not for printed circuit board cuz they should know that too!!!HP I can contact JC but be sure that's what you want cuz if I tell him _his wonderful HP
_ is summoning him he'll drop everything including his grad studies and I know you won't like that! So I don't want the blame!
Alright - Here's the plan - 'disputed' expansions will be 'un-linked' but left on the list for general reference - FWIW, as a courtesy to 'intermediate' electronics students/enthusiasts I'm considering inclusion of certain basic (albeit, perhaps, less familiar) quantities/parameters (on the list only) -- Thoughts/suggestions?HP I say eV has to go cuz anyone who doesn't even know that has totally come to the wrong place
While I concur with your assertion that 'PCB'→'Printed Circuit Board' requires no citation -- It is, nonetheless, my (well) considered stance that preclusion of ambiguity requires that expansions are accompanied by citations of any coincident 'full-forms' having relevance to electronics, physics or mathematics.
Here's the deal - I'll add them to the list as soon as convenient but link them if and when we decide to compose an 'amateur radiography' edition -- said decision to be the subject of another discussion/thread
Fair enough!HP I can contact JC but be sure that's what you want cuz if I tell him _his wonderful HP
I'll contact him -- Though I daresay attempted flattery of _his sainted HP_ is merely by way of rationalizing further squandering of his time on his 'true love' which being online gaming! -- Hey @Jazz2C ? At the rate you're going you have a brilliant future to look forward to! - Heck! With a little application you might even make highest ranking Dota2 player at your homeless shelter!
Indeed!I must say the repartee between Aleph and HP is always immensely entertaining. How y'all can maintain a straight face is beyond me.
It would seem the 'manufacture' of electronics tutorials and sausage share some common ground-- Please rest assured - we are getting there!As far as DSOs are concerned, feel free to liberally quote from my book:HP I say eV has to go cuz anyone who doesn't even know that has totally come to the wrong place
HP there are also some marginal ones but I say they can stay since you're just linking without digressing on tutorial
So abt additions you didn't include any abbreviations of radiology, radiography or radiometry terms which I say you should cuz that's not pure electronics so some ppl would appreciate that!
HP I say another good idea is to think about expansions for some types of test gear cuz there are multiple names for some instruments that can differ depending on location (Like SA instead of FDO and O'scope instead of TDO and like that) plus all the variations on the _scope_ theme like MDO, MSO, DPO, DSO, ASO, CRO plus variants by sampling algorithm and so on! And it's not just scopes! So think abt it cuz it would totally suck to chase someone away for want of equipment probably sitting right there on their lab table by another name

) to show for over a year's effort on a rather fundamental topic --- Hence I can well appreciate the significance of your accomplishment and the monumental effort back of it! -- Having composed several 'scholarly articles' in the course of my professional life -- My work here (on the tutorial) presented me with a 'rude epiphany' to wit: nothing is as challenging as instruction (Spec. conveying information to a broad audience) - Again KUDOS!Why thank you. I have to admit that it was a whole lot of fun to put together, and nowhere near as tedious as you might imagine. I already had all the material I needed; I just needed to put it in some kind of sane order.181 pages! -- I salute you sir!
We've a scant 17 pages (and, speaking for myself, one foot in a 'rubber room'
With utmost sincerity

Ah! But that's the most difficult task!I just needed to put it in some kind of sane order.
! Now is done except bill of materials and warning abt fluoropolymer breakdown products, right? But good sorting order can help! HP are you totally sure there's no way of finer linking than just to posts?
