You´ve made it also with a 20k - Would be interesting if you can test some more resitors, say between 1k and 1M.

I currently only have a 10K and a 20K of the Vishay precision film resistors readily available for testing. The 10k made things more interesting. Here are the results.
10K 0.1% Film resistor
Meter DCR 100Hz 1KHz 100Khz
DE 9.998KOhm 9.997KOhm 9.996KOhm 9.997KOhm
ET 10.001KOhm 10.001KOhm 10.000KOhm 9.993KOhm
Fluke 9.998KOhm ----------- ----------- ------------
So, in that case, the measured resistance drops, but not nearly as much as the 20k. Now, I am wishing I have a 30k on hand to test. :popcorn:

But we can already foresee a trend this way.
The greater the resistance, the greater the deviation in non-dcr mode.
It annoys me a bit right now that I don't have the ET4410 anymore....
At that time I had only measured capacitors and coils with it.

Here's a couple of precision low TC Caddock TF020R 0.01% types (large flat metal foil types used in DC precision applications), measured with a relatively new KS34465A (Kelvin Clips), TH2830 (Kelvin Clips) and DE-5000 with TL-21.
100K KS34465A TH2830 DE-5000
100.0088K 99.9994K 99.92K
99.0222K @ 100KHz 99.53K @ 100KHz
Cp ~ 0.79pF Cp ~ 0.45pF
20K 20.00119K 19.9991K 20.00K
19.800K @ 100KHz 20.00K @ 100KHz
Cp ~ 1.26pF Cp ~ 0.74pF
Anyway, might find this useful for comparisons.
Best,

A further proof that the DE5000 is simply an absolute godsend for hobbyists on a tight budget. :D

Agreed. I paid $147 USD for it and both sets of probes. I also know the DE-5000 is sold for about 1/2 that in Japan. That meter is absolutely a steal at that price. The ET-432 I paid $190 for the equivalent setup, and It appears that it is really only a 40KHz meter.
