I don't ever use a voltmeter so I might be doing this completely wrong but this is what I did. I set the dial to 10AC and took a measurement, was getting less than 1v (barely moves) on the 10AC reading. I should be getting 3.6v right? On OHMS setting I get 20-10k if that means anything (that just measures if there is any electrical current at all correct?). Again, this is reading the small 3.6v battery.
