Data logging both current and voltage at same time with 1 DMM

[Mattjd]

Has anyone experimented with logging both voltage and current with a single DMM?

Lets say I take my rigol dm3058e, I have it connected to matlab and have a bunch of drivers written that log measurements for me and display them on a graph in pretty close to real time.

If I switch modes, between current and voltage really fast and capture a measurement. How well do you think this will work? I mean the dm3058e does have a dual display measurement, I just havent tried doing this on my computer yet.

If anyone has ever tried it I would love to know. Or if there are alternatives I would love to know also.

Have you seen this video?



Checkout the code in the comments , they are measuring Voltage and Resistance, so it's a matter of trying out

I had not seen that. I was just thinking if you would be able to sample each signal fast enough to be able to adequately log them both
