Title: UNITREND UT61E service pack 1, hack, improvements, new features
Post by: blankfield on April 28, 2013, 03:06:30 PM

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 (http://www.youtube.com/watch?v=Q6pBOpQ8jes).

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
blankfield
