Help with data logging on DSO

[Ldg]

I'm new here, so bear with me.
I'm waiting for my SDS1072cml to arrive from amazon.
Thanks for the help here to make that choice for my first dig scope.

One thing I want to do with it, is to test some solar charge controllers.
I also will test some 12v chargers, supposedly with de-sulfation (provides high current pulses)
I want to record Voltage on one Ch and Current (through a shunt) on the other.
I would like to do this over a 24 hr period.

Could that be done, only using the internal memory, or would I have to record to a USB drive, and view the results on a PC?

Thx for the help
LDG
