I just bought a new multi-range digital-multimeter to help with some electrical problems i've been having. I bought a book from sears for $10 that pretty much gives you an electrical engineering degree after your done... Anyway i still don't know if i'm using the meter correctly. I know how to check for voltage and stuff like that but i'm not sure if i am checking the resistance correctly. When i check for ohms (the up side down funky "U") the meter flashes numbers sporadically. The number that it flashes first is usually the specified resistance for the circuit i'm testing, but then it starts flashing numbers like crazy until it goes down to zero. Is this what is supposed to happen? Thanks for the input!
