I can't find any information, besides one youtube review
Anyone own it?
How is it compared to de UT139C?
I'm interested in true rms, temperature, low price and if possible connection to PC.
That's why i end up with this two choices UT139C and this "unknown" ADM20. The ADM20 has USB PC connectivity.
Is BSIDE ADM20 USB connection protocol known?
any suggestion would be appreciated, thanks in advance.
ps: ADM20 instead of using IR connectivity use direct usb connection? could it be harmful to the PC if some problem occur in the DMM while measuring?

It is not fast DMM
Go with UT139 or same chip AN8002 890 etc
My own recommendation is MS8250C - extra speedy and 6600 counts + REAL bargraph

A little late to this topic, but I've put out a simplified multimeter software for this meter.
https://github.com/inflex/BSIDE-ADM20
Still tweaking it and filling out all the features but for now it working with Windows.
What's interesting is that the chip used in it (DTM0660) usually has a 14~15 byte packet as I understand but this one seems to have been padded out to 22 bytes and doesn't use the shot-gun of bits across bytes to represent the segments on the display.

Perfect timing Mr Inflex *yoynk* TY for the code :-+

Of all the people in the world, fancy you happening to pick up this code. Good luck with it, aside from the preliminary work to get it "working well enough" I've not had much of a chance to do much more.
I want to do a wifi or 433MHz conversion for it next.

Can owner of this device take different measurements and provide output of the serial data that it transmits?
