What are 6.5 Digit Multimeters Good For?

Lead free solder is Belgium's version of 'Hold my beer and watch this!'

lots of super expensive stuff.

And when it does, it's out of support, and the bean counters have put all the spares through the crusher.

"Electricity is of two kinds, positive and negative. The difference
is, I presume, that one comes a little more expensive, but is more
durable; the other is a cheaper thing, but the moths get into it."

Just because you can't grasp the ramifications of hierarchy and
pyramidal structures doesn't mean I should be bound by your rules.

Really?

Do you think NIST's standards are verified with Simpson 260's?

Omigod, you're just so cute!!!

Stupidity is a pyramid scam, and he is caught and still trying to achieve escape velocity.

As opposed to you, DimBulb; loving his stupidity so much that escape will never be attempted.

Actually, that 60 Hz transformer you're talking about isn't a linear transformer.

Linear as to mean opposed to switching. Not sure where I picked up 'linear' to describe that. It's probably old school.

I am pertaining to that layed silicone steel core thing with all the copper windings that plugs into the wall.

According to

I should be comparing ferrite core with laminate core. Therefore...let me rewrite .. My assertion is that antiqued instruments help qualify them as boat anchors due to being heavier than instruments with an equivalent smps.

Idiot, if the rules would have caused the apple to elevate there would
have been no Newton and you wouldn't be posting the crap you do since
there would be no you.

In any case, Newton had nothing to do with feedback.

Here's a clue:

Linear supply line/input transformer.

stuff anyways.

or LIGO,

Why do need "accuracy" to 0.01%? What are you trying to measure to that kind of accuracy? ...Jim Thompson

You are missing some concepts here. =20 There are things called reference cells, the voltage across the=20 terminals is dependant on the chemistry/physics. Similar to and=20 far lower tech to make than bandgap references. The terminal=20 voltage can be determined to 6 places before putting the meter=20 leads to them and are repeatable and reliable. Ratiometric methods can maintain resolution and accuracy in a large=20 variety of situations, see R/2R DAC systems. With these concepts in hand you would not have bothered to make your=20 comment. Or maybe you do not credit anyone else with these few bits of=20 typical electrical engineering knowledge.

ITER, or LIGO,

So, you know some interesting tricks to make an AC current source=20 accurate to 0.01%? A lot of people would interested, especially if=20 it was a clean sine source. With a good clean DC current source i=20 have seen measurements all the way to 0.00002%. There be tradeoffs=20 here.

Do people still use standard cells?
