Hi,
I am trying to calculate how long my 4 AA battery would last in my circuit running at 3.3v with my multimeter. So I need to find out the total current drawn. I cut the line after regulator 6v to 3.3v and place my probes of the multimeter in series touching my cut line. I got a read out on the multimeter in mA but the strange thing is my circuit does not come on. If I put the two probes together my circuit come back on. Am I doing something work? Have anyone encounter this before? Maybe the multimeter draining to much current?
Thanks,
Sheng
