Did I completely miss it, or did they make no mention of the important metrological specifications like accuracy and drift in that video? He seemed completely obsessed with noise.

I guess we both did.

Looks to run around $11,500 on price..

It looks to have too many features crammed inside for me to trust that they got any of them right. Jack of all trades...

yeah, cramming it all in one box makes for less total equipment on the bench, definitely not good.

What I want to know is how frequently the areas where 8.5 digit meters are needed and the areas where 30A current measurement is needed intersect.

I can't think of a single one....

And for those few cases... Hmm, I can't think of anything *cough*externalcurrentshunt*cough* they could do. I guess they're just SOL if they can't afford this meter.

And if they need that nice, low noise, how about.... nope, can't *cough*averaging*cough* think of anything.

Sounds like a challenge for the community here.  :)

Regardless, I still hope they send one to Dave!

I don't think the mindset that leads to that IMPORTANT NOTICE mixes well with "Don't turn it on, take it apart!"...

I sense some connection with http://www.timeelectronics.com/ (http://www.timeelectronics.com/)
Product area, look & feel, geography  (and something else...).

Yeah. The domain names are registered in towns 49 km apart. How many unique metrology companies could there be in Kent?

30A on the bench none the less...

Or at least measure its resistance.

its probably a 3458A inside of a box with a rasberry pi transducer computer and a current shunt off ebay. Easy 3K profit.

How many shoes per year would that take?

When I tried to get a Fluke 8508A and could not find one, I also considered this Transmille 8081. Therefore I added it to my comparison spreadsheet.If there is interest I can show some comparison results.
