Your Experience on LCR Meter DER EE DE-5000 / Hantek 1833C

<< < (4/7) > >>

mawyatt:
The DE-5000 (bracket value from Hioki IM3536) for a 1/8w leaded 1% 1M metal film shows:

DCR of 1.0015M (1.00188M)
Rp @ 100KHz 1.0016M (1.00102M)

Best,

TimFox:
The high-frequency behavior of resistors depends greatly on the internal construction.
For old-fashioned A-B carbon composition resistors, the talc grains mixed with the carbon particles "short out" the carbon capacitively at high frequency, so that the equivalent parallel resistance is surprisingly low.

David Hess:
One thing I like about the DE-5000 is that the accessories are readily available, so for instance another set of the short Kelvin sensed clips can be purchased and then converted into a long set with coaxial cables.

I would not mind having a low frequency VNA for component measurement but until then, the DR-5000 has been outstanding for me.

sounds like a fantastic idea... not sure how to do though? any guidance or help on this matter very much appreciated

edit:

or can we make from scratch? for example with a pcb to insert into the slot at riight angle. then solder to that perhaps with a 2nd joining board at 90 degrees. maybe things like this should be possible? although idk if it is really worth it instead versus modifying an existing tl-21 like you say

also debating whether or not to get a 2nd  nother tl-21 initially. or just sacrifice the one it came with.... and then if ever change mind can order another one to get that stock version back again

so really the question is do i make by purchaing other existing coal kalvin clips pre made. or make from pieces of coax. to then solder some probe handles which is more custom or something than an off the shelf pair of kalvin leads

or you know, to make some bnc termination onto as an adapter making from the existing tl-21. that can plug in unmodified kalvin probes of other brands of esr meters

After I bought my DE-5000, I picked up a second TL-21 just so I would have the hardware to make a second set of more useful Kelvin probes.  The TL-21 provides access to the 2 force connections, the 2 sense connections, and 1 ground/shield connection.

Moving interrupted this project so I have not finished it, but my plan is to run 2 thin coaxial cables to each clip, with 1 for force, 1 for sense, and the shields connected to the ground/shield connection.
