Yeah, just received 121GW 2 days ago, and the firmware reads 2.05,  no idea if that's actually from Welectron, but I ordered it directly from EEVBlog shop online.  Delivered to UK by DHL courier and it originated from Australia.

Happy with this product so far.  Thank you so much.

Hi, I have not read all thread trough so maybe this note will be not a new. But in my opinion AutoHold mod is slightly raw, especially in resistance measurement - it takes all my time to get value of a single res. In the same time in a basic mode I see that the value jumps in a least significant digit only. And it is very disapoint that I cant check 5% resistors over the board as fast as I have expected  :P
I understand that design and consumer satisfaction it is all about trade-offs. But my vision of this process is to give user freedom to select between A) more digits, sometimes more noise and more time to get a value, and B) less digits - faster response.

We have a "1 kHz" mode which enables filter. So maybe it is reasonable to make it available for other modes?

One more. Looks that the AutoHold mode does not depends of Auto range or particular range is selected. I thought the overall time to get hold the value is a sum of the time required to find the range and the time required to ensure that the value is stable. But looks that it is not. Very strange

If required I will make a video report later.

Correct, all my units in stock are the latest 2.05. Welectron were just the first to get it.

Thanks Dave for your reply.  Can I ask what is the changelog for 2.05, please?

From Dave.

I now have v2.05
They changed the low pass filter curve to better match the performance of the Fluke 289, which I guess they are using as a sort of reference.

Got my 121 finally, on a circuitous path through a buddy in New Zealand because they can’t shop from Australia to South Korea for some reason.

Been working great! I was testing a board where I can program resistance (like a digipot) and I had the 121 connected for some time. A few times during the day I heard this loud alarm beep. The first couple of times I thought it was some alert from my aircon or electric fan. On the third time I finally realized it was the 121 telling me that it was about to auto-shutdown. That’s one loud beeper!

Yeah, this multimeter is great. I have upgraded my leads to Pomona, good stuff :)

Hi all. I have two questions:

Firmware 2.05:
Where is it? on
https://www.eevblog.com/product/121gw/
i still see 2.04 as the latest...

Shim:
I don't know the full Story with the shim that some revisions needed because of a wrong pcb thickness, so:
Do i have to check if my meter needs the shim, or were no meters sold without that fix?

PS:
@dave, there's an issue with reporting an issue (not that i had one, just saw this:)

Dave posted the 2.05 firmware one page back.  Here's a link to it: https://www.eevblog.com/forum/testgear/eevblog-121gw-discussion-thread/?action=dlattach;attach=1213626

I'm sure there are units out there where they are "supposed" to have the shim but don't.  Personally I think the shim is not always needed.  I have two that came with the shim but removed it because I thought the switch felt better without it.  Zero issues so far.  If I need it after the contacts wear, I'll re-install.

IIRC no meters were sold without the shim. It was limited to the Kickstarter shipped units.
