Thanks, merged with a few minor changes (reordering of entries, changing
"UT-60E" to "UT60E" for consistency).

Have you tested the temperature mode specifically? That's the only one
that might need special handling per-DMM.

Yup, thanks. We know about the dumps and might add some more DMMs over
time, but it's preferrable to see if people (like you :) report new DMMs
after also actually testing them.

As for the VC-820/UT60A and VC-840/UT60E we cannot be entirely sure
they're actually the same PCB. It is indeed very likely to be the FS9721
chip in all of them, but from the PCB photos we have seen so far the
VC-820/VC-840 are specifically made for Voltcraft since they have some
silkscreen markings suggesting that, e.g.

It would be interesting to see PCB photos of the UT60A/E, so if you want
to open your device and upload some photos in the wiki please let us
know and we'll create a wiki user for you (tell us which username you'd
like). Even without PCB photos, one or two photos (top, bottom, etc) of
the device would be nice for the wiki (without opening it), see e.g.

Thanks, Uwe.
