Questions according DMM

[Karsten Welskop]

Hello,

I'm new to the DIY World. I would like to buy a DMM, but I dont know
exactly what features are necessary and which not. Espacially I would
like to know what does 3, 3 1/2 or 3 3/4 display means.

A further questions is the meaning of the "digit" error (e.g. 0,5% +-
3digits). Do I need a true RMS DMM?

OK give me some hint.

Thank you very much.
