Hi!

I own RDTech's UM25C and would like to let you know that rd-usb works with it just fine with one modification:

basically, as UM25C has resolution of 0.001V and 0.0001A so voltage and current encoding are changed to make room for that resolution.

Done. Now you can select version and UM25C will have extra modifier for voltage/current. Thank you.
