I'm waiting on a Mouser order with the following:
10nH
100nH
10uH
100uH
1mH
10mH

Nice ... may the question rises about the used tweezers as I use a Kelvin 4 pol one. As may this draws soon an issue.

But first lets see what you get.

I don't like wired tweezers at all. I use an SMT fixture, or Shannon ST-42 tweezers for SMT stuff.

I actually disassembled the tweezers that came with my DE-5000 to make kelvin clips.

Hmm, your looks like the TH26008A Magnetic ring fixture ...

as performance:

"When the test frequency is ≥100kHz, the capacity is ≤3pF, or the inductance is ≤1µH, this type of SMD fixture is suitable."

so below 1uH not supported nor possible for any measurements.  :palm:

My question is also on this "TH26008A Magnetic ring fixture", how to go in the supported MHz regions as the TH2830 max as 100kHz.

You read that backwards. It says less than or equal to 1µH. We'll see what it does in practice. It's not the same as that anyway, it's a knockoff. Real world testing results may vary. 😉

And for good reason...
The nice thing about known components is that you have/get data sheets for them.
So you can verify whether the values are correct.
To be on the safe side in this respect, you measure as the manufacturer had done when specifying the values, so far so good and clear.
And now comes the "Wo-hoo"... ;)
I rummaged through all the data sheets that could be found for your parts list and listed the respective test frequencies that have to be used to arrive at the same values.
And that's where it usually gets sporty with an LCR measuring device that can "only" do 100khz/200kHz....
This is just information for the case that you measure "strange" things with your TH2830/32.
