I got a new Uni-T UT210E Pro, the one with the gray clamp, not the old org one with the red clamp and I could not find anything regarding the compatibility of the regular mods or hack on this new "Pro" version.
The only difference really seems to be that in the V modes there is a Hz frequency mode added to it.
This Hz mode seems to be different to the one mentioned in some mode list tables on the long chinese datasheet.
I implemented all suggested changes in the UT610E so far, as I did on my old UT610E and all works. Even I have 4 V-modes on my old one (after being modded) DC, AC, DC mV and AC mV the same applies after modding in the Pro version, except the 4 V-modes now have a Hz mode added automatically after each AC selection ... in summary now 6 V-modes with 4 entries in the 8E, 9E, AE and BE fields.
Also please note that the EEprom is a 24C08 (as compared to some docs I found related to the hacks, stating it as a 24C02) and has some entries in the 2nd 256 byte block, so please be careful by updating the EEprom.
This serves as an add on to all the other modding and hacking instructions for the UT210E on the net
