A look at the Uni-T UT210E
CustomEngineerer:
Is there a good way to tell which chipset you have if there are no markings on the chip?

Sometimes the markings are faint. Shine a bright flashlight at an angle on it.
If there truly aren't any, you can play it safe and flash the 0660 version. There may be a way to compare the rest of the PCB and/or serial number to figure out version you have. When did you buy it? I haven't seen anything bought recently with the old chip.
CustomEngineerer:
I got interested in these clamps a little over a year ago, and went ahead and bought one in either May or June of 2017. It was shortly after that that I started seeing posts about the new chipset, so its possible it could be either. I had bought it with the idea of hacking it for fun/learning, but never got around to opening it up until a few days ago. I had tried shining different lights at different angles, with and without magnification, with and without spit, but I just can't see any markings on the chip. It doesn't look rubbed/scratched off, I just don't see anything on it. I applied the non-chipset specific modifications with no issues, and was thinking maybe a way to tell would be to try to apply the chipset specific ones and see which worked, but wasn't sure if doing this could cause any issues (probably not, but figured better to ask before trying).

It won't hurt to flash the mods for 10,000 counts but if you have the old chipset, it may break AC readings. If it does, then flash the 0660 chipset mods instead. See my ino file a few posts back. I have both new and old mods baked into one ino file, you just have to uncomment and comment certain lines based on your model.
CustomEngineerer:
After more thought I decided to just go ahead and try. I applied the DM1106 specific changes with no issues. I wasn't able to test that the 100A range goes up to 1000A, but I did test that it does go over 200A (I do realize this doesn't really tell anything other than the range did increase), and in all other ranges/measurements I do now have 9999 counts. So from what I've seen, that should mean that I do have the newer DM1106 chipset.
