Looks like Kane (UEi) have released the new 555 multimeter

You might have seen a glimpse of this in one of my videos where I have an EEVblog branded version they sent me.
It's based on 121GW design, essentially it's their own upgrade to the 121GW and AFAIK is only sold in China. Don't know if it's new firmware or not.
It's got true energy measurement using a dedicated chip.
FYI, I had no knowledge of or input into this design, one day they simply told me that they had it.

The manual mentions an ETL listing, so it might end up being sold internationally.

Is this "Kane (UEi)" who's also responsible for the 121GW firmware?
-
In the glorious name of Kane. Every technician needs one.

I went to the URL posted, but there's no way to buy one of these DMM's. Google wasn't exactly helpful either.

Yes, same company, same team. Kane/UEi/Finest
They designed and made the 121GW.

Here's the auto translated manual using this service: https://www.onlinedoctranslator.com/en/ (https://www.onlinedoctranslator.com/en/)
(had to zip it as it was >4000KB)

At first glance it does not seem to have the high 15V diode mode.
But it has the low burden feature and the SD card.
It also has Conductance which 121GW do not.

You can't kill the messiah.

Simultaneous AC and DC! Nice! I wonder if the update rate is decent with both enabled?
-
The manual has the complete process for Capacitance calibration:

which seem similar to 121GW but this is still incomplete in its manual (Mars-2020).

IMO, the 15V diode check was the weak point of the 121GW's electronic hardware design. With this one feature removed, it would have been much easier to make the 121GW very robust. Even if they addressed this, the countless switch contact designs, shims, heavy plastic wear in the switch area, cracked plastics on the input connectors, cracked plastics with the the card reader, lettering that is easily removed with common solvent, battery springs that pop out, suggests they don't have a good idea about the mechanical side. Then there's the firmware...

Correct. I believe that was dropped so they could get the increased CAT rating.

I wonder how much the rest of the mainboard has changed, other than the addition of a new chip.
(It looks like their website is down at the moment, 403 forbidden. I was hoping there might be pics there)
