Upgrade from a DER DE-5000 LCR meter
Giallograle:
Got it thanks Josh, getting info from Tonghui's site is like pulling teeth so the following took an inordinate time...
There don't seem to be any good alternatives to Tonghui test leads, so:
* TH26029B SMD Kelvin tweezers (white, box with 2 locking BNC connectors) 5Hz-100KHz, around $40 here
* TH26009B SMD Kelvin tweezers (black, box with 4 locking BNC connectors) DC-15MHz, around $95
* TH26008A SMD test fixture (box with 4 locking BNC connectors) DC-120MHz, around $140
Wondering whether the cheap tweezers are good enough for my purposes, audio frequencies, measurements down to pF; not critical at that level but it's approaching the meter's limits? I'd appreciate reliability, repeatability and accuracy in measurements, so if the 26009 is more suitable I'll go with that.
Test fixture is probably too good for the 2830/32, and me!

Is there anything I've missed or should consider?

Hi Giallograle,
since the meter has not been mentioned you might like to take a look at the Matrix MCR-5200 as option. It measures up to 200kHz, can be programmed and is avilable new for ~650-750€ for instance at eleshop or digikey. The meter supports a fixed set of measurement frequencies (40Hz, 50Hz, 60Hz, 80Hz, 100Hz, 120Hz, 150Hz, 200Hz, 250Hz, 300Hz, 400Hz, 500Hz, 600Hz, 800Hz, 1kHz, 1.2kHz, 1.5kHz, 2kHz, 2.5kHz, 3kHz, 4kHz, 5kHz, 6kHz, 7.5kHz, 10kHz, 12kHz, 15kHz, 20kHz, 25kHz, 30kHz, 40kHz, 50kHz, 60kHz, 75kHz, 100kHz, 120kHz, 150kHz, 200kHz). There is also a Matrix 6000 Series with contiguous frequency support or the big Brother MCR-8500 which measures up to 5MHz but is considerably more expensive (around 4500€)
Cheers Traceless

The TH26029B is a toy without good shielding.
Did you mean $195 for the TH26009B? If you can get them for $95, get me one too. 😉
Look at the Shannon ST42 LCR tweezers. They max at 10kHz, but that's plenty for audio. I use them more often than my IM3570, but I wouldn't part with either. When I still had the ST2832, it was the same story. ST42 for a lot of stuff, and then the ST2832 for anything beyond it. Or I used the THT fixture on the 2832 to quick test THT stuff faster than using the tweezers.
Giallograle:
@KungFuJosh Yes, that's $95, around retail price here, plus I'll have to pay (expected) 7% Vat on import here. So I can order you a set and post them - looks like it may be around $17 tracked.
Actually I think I can get them for a little less today, it's the last day of the Chinese 11/11 sales, so they'd come in at a shade over $100 delivered.
This is coming from Taobao (China), to Superbuy who check it looks like what it's supposed to be, consolidate it with a bunch of other stuff and ship it to me in Thailand.
PM me early today if that's of interest. And anyone else who's contributed to this thread.

Everybody has different needs. If you don't need it, maybe that's the answer.
Personally, I use LCR meters all the time for different work (mostly related to audio/guitar stuff).
I would suggest getting the Shannon ST42 tweezers as your first LCR. It should cover most of your needs, for a good price and performance. I use the ST42 to verify component values for most things (anything that fits easy enough, or is within range) before installing anything.
Thanks,
Josh

I was just wondering if anyone is doing something like measuring ultrasonic transducers, component development or some physical measurements. I don't find them particularly interesting for component measurements, because all the components I use have to have their characteristics defined by datasheet.
And when I pick it up it's to measure a cable inductance or some other parameters that are undefined.
I understand why you would need it for component development.
