Hi all,
I did some improvements to UT61E, this mod basis on one that I've found on EEVblog forum but I decided to add some silicon into UT61E so additional fatures are controlled by pressing yellow and blue buttons for 1s this is
Youtube video of final effect.
In few words new features:
*backlight for 60s (on/off)
*auto power after 15min function (on/off)
*RS232 port (on/off)
*MAX/MIN/MAXMIN function this is different like peak max peak min
Bellow all necessary materials for this modification.
Cheers
