IET DE-5000 LCR Meter in UK

[Srbel]

I have DER EE. Version for Japanese market, so I got manual in Japanese.

This is the correct manual: http://akizukidenshi.com/download/ds/deree/DE-5000_manu_en2p.pdf

I have just received the unit few days ago, and I have only tried it out a bit. I have not had the time to read the manual in detail yet.

No 1 milli Ohm resolution.
I only get 10 milli Ohm resolution on DCR.

I can not measure ESR on high frequencies (100 KHz, 10 KHz or even 1 KHz on some), if capacitor is more than a few hundred uF.

[kripton2035]

measuring ESR at the milliohm is useless, unless you're doing RF stuff
in that case a professionnal LCR meter is required, but it will cost 10x the DEREE at least...

[PA4TIM]

Indeed, that is useless for many reasons. But the opinion here is that the IET is the same as the DEREE. And I just tested it because I became curious. I measured the ESR at 100kHz from a 6800uF cap with my IET DE5000. This was 0.023 ohm. So you do something wrong or the meters are not equal.

[kripton2035]

measuring a 2200µF/25V (that's the biggest I have) with my DEREE gives 0.035? so I get the milliohm (@100KHz)
you must force the measuring system to measure Rs (and not in auto mode)

[Srbel]

OK, in Rs mode it can measure at 100 KHz. I have tried Panasonic 3.300 uF 25V and it measured 8 milli Ohm.

But, in DCR mode (not measuring capacitor, but a wire to measure resistance), I only get 10 milli Ohm resolution. I can only get 1 milli Ohm resolution in ACR mode. :/

So, what if I want to see what is the best inductor I have in terms of DCR?

mine came the other day, seriously its built like a tank, I mean, does it really have to be the size of a house brick !. I could use it to float across the channel to France on.
