This should address users physical accessibility issues. Tried a BT file transfer from Windows 10 PC but the 121GW ignores the "Receive a File" request. Is it an issue the software stack to implement this feature is beyond the hardware's capability?

It was considered very early on back in the development but it was deemed to be too hard. IIRC it needed added support in the bootloader code, so I don't think it's even possible with just a firmware update.

What if you could "play back" the logged data on the display so the app could read it?

Is this meter still available for sale in the US?  I only found a couple of used ebay listings.  Amazon says no stock. 

Is there any issue with ordering directly from the site - customs holds etc.?

No customs issues for the US. It ships via DHL express courier from my site.
I do not have enough stock at present to restock Amazon.

About a month ago I bought three more multimeters, two £40  ones with bluetooth so I can monitor two voltages and display the values on the iPad and a 121GW as an accurate decent quality one on the bench.  I have a Keithley 2100 and two Philips bench meters but sometimes it's easier just use a hand held meter.  My first impressions are good and I like the probes.  The possible issue I have with the 121GW is reading small values of resistance.  I have built a bench adjustable load 2/4/8/16 ohms and the new meters and bench meters all work with it but the 121GW just reads that there is no connection.  I can read larger values and the accuracy matches up very well with the keighley but small values are not working.  I have ended up switching leads and using the cheap ones which seems silly

Any ideas? 

CDaniel:
But what is showing when shorting leads ?
