How do I scope an alternator diode waveform with a Verus. I can't get that ac ripple pattern. Is there a way to change to AC coupling because all settings are in DC mode. This a new and wonderful machine and I want its full potential. Thank you for help.

Mine is out for repair right now so I cant verify this but the A/C coupling feature should be in the same line where you select peak detect and filter. Than I like to set the timebase to 10 or 20ms sweep than pause and zoom out to get a clearer picture. Than look for consistent "noise" in the capture, than I like to disable the alternator and see if the Noise is gone. -
You can change to AC coupling either by clicking at the icon in the data section of the scope:

Or go through the Setup menu:

Much Mahalos to: Mr. Chip Wright and Mr. Orevin. I'll give both suggestions a try. I think I tried AC coupling in setup. I found a wire hookup made by AES for $53.00 but both suggestions I believe will work. Thank you again.Comment

The AES cable was for the original vantage as it did not have a way to ac couple. It has a filter in it to take out the dc portion of the voltage.Comment

all you need to do is hook up yellow lead to b+ and black to ground, both at battery. open up lab scope for volts dc. adjust channel 1 to 200 or 500 mv and set sweep to 10 or 50 ms. click ac coupling and peak detect. you should be good to go. if you want i can email you some captured waveforms.Comment
