that must be the meter the Chinese use to rate batteries 6000mah reality 200mah

Previously: "This is a great meter for $9!!!" BUY BUY BUY
Now: "This meter is dodgy AF!!" SELL SELL SELL

It's quite likely these are genuine units that simply failed quality control at the factory, which is why we are seeing variants and different faults between units. Whoever was in charge of discarding them obviously leaked them onto the open market instead for a quick buck. The Shenzhen markets are filled to the brim with this kind of stuff.

Big OEMs don't bother with defect product handling. They hire a subcontractor to collect the defective end products for safe destruction. This is done in order to prevent unauthorized product sales to the end user. After that the products go to a waste recycling company. This is the way we do it in the company I work for(automotive). Obviously in this situation this line was broken. Someone had decided not to follow procedures. These products were scrapped as defects but never reached the destruction stage.

It would be interesting to know what is causing the wide variation in the performance of these devices. Faulty component(s), programming, assembly?

The last time I was this early, Solar Roadways actually generated its own power.

Out of the two, one has working Meter functions, the other has working Process functions.
Between them you have a meter that can do everything, but still cannot be relied up, and has a cal certificate written in pencil.
I'd be up for the challenge of putting the working parts from both into one meter, if you do decide to give it away to an Australian.

8:45 "You press function and it's going nuts!" (Maybe FUNC meany FUNKY and not FUNCTION? :-) )

I've tried ordering some obviously mispriced items like this but they always turned out to be a scam where they mail a fake package to some random phony address in order to get a tracking number then by the time the package is delivered to the wrong address the seller is long gone and I had to file a claim for a refund from Paypal. I'd like to know what they sent in the fake package but it didn't come to me.

You could part it out for more than you bought it for. Still worth it.

[NetworkXIII]

These look like reject units that someone fished out of a dumpster.

3:34 I cannot stop crying after reading this tragic story.

As said on the last video:
Thrown away from the factory stuff, faulty production.

[Petertronic]

Did you compare the pcb's in the meters? I was wondering if there might be components missing or something.

[damnyutoobe]

I'm so glad I couldn't find one. Thanks Dave!

[Northerntar]

After this gold rush the Chinese are now going to look even harder for rejects to sell.

[peteb]

Quite happy i didn't get caught up in the woo-woo excitement! Already own enough test gadgets so saved myself the $9 & the ridiculous hassle. Really interesting sitting on the sidelines watching the turmoil of it all though....

On the second meter test are your probes in the correct position? Current sourcing. Check around the 10 minute mark.

[Valenorious]

Doesn't this call for a teardown and attempt at a fix? Or atleast a "wth did you think you were doing when you designed this!"

[msg]

I would like to see a teardown of this thing, maybe there's something visibly wrong with it? Does it have original parts or their numbers were also scratched off?
