You had intended 1nF/1kHz for this, then you only get one value, namely the value for 1kHz.
In your next table, I would not include this as a range to be tested.

I copied the note from the cal cert that was shared:
Martin72:
Ok,

Then I have to say it the way you wrote it in your table. ;D
It may also mean something other than the DF that comes to mind.
Edit:
Ah, this could be different 10nF caps...

I still have no idea how to test it. 😉
Martin72:
It can only be that capacitors with different dissipation factors but the same capacitance have been used.
This is because the frequency and capacitance are the same for all ranges (10nF/1kHz).
But now find the right capacitors for it...
Or the different losses were created "artificially".
Tonghui should know.

🤣🤣🤣 They should, but if they do, they'll never tell me. They're terrible.

I sent my results to my ST contact. If he knows, he might tell me.
