Is DVM is digital voltmeter?

 

Yes. If you hover your mouse over the dotted underlined acronyms it will display the definition.

how do I check the AC noise whit it?

 

Red probe to touch the BATT terminal.  Black probe touching the metal case of the alternator. If the reading is poor touch the negative battery cable. Optimally you want to measure at the alternator not on other wires or battery terminals.

I know how to check the voltage not probe.

 

Same as doing DC but you select AC on a small scale some where like 2V AC or 200mV AC. Now like I said above red to the BATT terminal and black touching the case of the alternator.

I bought a rebuilt alternator and installed it. i'm getting 14.19 charge normal - 13.17 under fully load ( AC on max - head light - fog light - 4 way flash - radio on - interior light on - cargo light on ) + grid heaters on and off 12.19. Ripple form BATT's - BATT positive to ALT case - BATT negative to ALT and finally ALT it self like showing on the video unfortunately I'm reading 30.5 AC voltage I don't no is it acceptable or not? should I go ahead and return it an get the other one? what is your suggestion?

Cheap DVM... It doesn't have a AC scale in the 2V or 200mV range. Need at least about $100 DVM like my Fluke.
