I can only speculate why it is jumping around. It would require a good o'scope to find out if it is "random", ripple (residual AC) or high frequency artifacts from the power supply. It is all speculation. Someday I'll be motivated to do some experiments and even look for noise or distortion using a spectrum analyzer, which we make, so I have access to.
Your DMM jumping around when not making measurements is completely normal, by the way. If you want to see it stable touch the two leads together. -- regalma1 ------------------------------------------------------------------------ regalma1's Profile: http://forums.slimdevices.com/member.php?userid=6658 View this thread: http://forums.slimdevices.com/showthread.php?t=90742 _______________________________________________ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
