I have to make a comment about auto ranging DMMs. I have been fooled a couple of times by mine, because I was expecting no voltage, checking a 120v A/C circuit, and was surprised by it showing 120. Only after several minutes of "what in the world" thinking did I raalize it was 120 micro-volts. So they can be helpful, but you have to remember to look at the range it chooses.
