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.
