The results from a DMM for the value of an electrolytic is not really comparable to the results from an LCR meter.  See this thread: https://www.eevblog.com/forum/testgear/about-capacitance-measurement-with-dvms/msg489690/#msg489690

Click lower. 😉

I included the DMMs only because that was an improvised reference set of caps to see if my meters drift over time. I figured I might as well include the DMMs in there. I'll eventually do the same thing with a set of resistors.

Click lower. 😉

Here's what I see to click on.  If I click on the thumbnail image of the spreadsheet, or if I click on the text description below that, either way I see a picture of your DE5000.

Weird! Maybe your browser cache is messing with you?

That doesn't happen for me.

Anyway, it's the same as the image in the post anyway. You can right-click it and open it in a new window if you want it bigger.

Those TH2830 / TH2832 look mighty interesting. Only thing they don't have is external DC bias which would be handy to have (up to 25V or so).

Don't worry, Mike has a project for that 😉:

I've only ever tested at 1V. Can somebody enlighten me to a situation that higher voltage would be helpful?

Thanks,
Josh
