A look into my petty cash allows me to fulfill the desire for a usable LCR meter. So far I use a GM328A component tester. I am torn between DER EE 5000, Hantek 1833C, actually even a UT-612 would do, but it would also do for a UT-622C.*
I haven't found the optimal device yet, I don't need specific advice either.
Rather an idea of how important advertised features actually are in practice:
1. why DCR when I have a good multimeter? And isn't a good Rs resolution also enough? (UT-622C has no DCR).
2. how important in practical repair operation are the additional frequencies (400Hz ... 50, 75 kHz) that a Hantek 1833C offers?
3. are different measuring voltages (1833C 0.3/0.6, UT-622 0.1..1Vrms) possibly especially helpful for in-circuit measurements or is a suitable range selection not already sufficient for this?
I will never do (I know: never say never) high quality audio work nor design of circuitry of switching power devices or something like that.
*From the price point of view, only the UT-612 stands out rather below (~140 Euro). A DER EE 5000 kit comes out @190 Euros after shipping and customs from Japan (maybe cheaper via banggood), a pure 1833C will arrive in a few days for 183 Euros (cheap tweezer is here, a Kelvin clip cable is home made for additional ~20), the UT-622C (including Kelvins) is about 250 Euros. Wonder if the UT-622C is worth the additional fee.

P.S.: what are the best (technician) words for a) a thing which only gives you an idea of the measured value (German "Schätzeisen") or b) a thing which delivers all needs in a combined way (like an animal which gives you eggs, wool, milk and (lately) flesh (German: "eierlegende Wollmilchsau")
