How to use a voltage meter

[wontonflip]

I'm clueless when it comes to electricity. I got this GE Digital Multimeter....no clue how to use it when checking for voltage in my tank. I stuck my finger in my sump, and it hurt like hell. I checked with my voltage pen checker thing, and it definitely registered something (the dt did not seem to be affected). So. How do I use this thing??

I have this, plus of course, the red and black probes:

the only way that i know would be to put it on volts ac and put the black to a ground like the round part of ur electrical plug and the red lead where it hurt, and yes im an electrician for 12 years so hopefully this help.

This is correct.

I also had some help from Kid last night :) I set it to 200m (then also tried 20m). It detected around 001-006 (I don't know what unit it is). No clue if it's harmful or not. It's in the sump. Nothing detectable in the dt. But I will be going to the lfs today to see if they have a ground probe.
