LCR meter reccomendations, mostly for measuring ESR on e-caps
RiRaRi:
Hello. I am looking for good quality LCR which can measure at different freq. I need it mostly for measuring caps. I was looking at popular DE DER5000 and more expensive BK 880. Which LCR do you use for this and which one is good quality option for this purpose?
tautech:
Used smart tweezers only for years and recently got a pair of these:

Top product at a good price and don't think you can't use SMD tweezers on thru hole parts....have for many years.

I use DE DER5000 and am happy with it. And I don't need anything else.
There is only one minus. DER DE5000 does not remember the selected mode when turned on. When turned on, the AUTO mode is set in which he himself determines the capacitor, inductance or resistor, frequency 1kHz, measurement D. But I'm used to it.
The second disadvantage is the possible need to purchase additional tweezers or crocodiles to obtain a terminal block in order to independently manufacture a Kelvin four-wire connection.
But in any case, I am very pleased with the device and glad that I did not buy something from another brand.
Be careful when choosing. Many LCR meters do not have a Kelvin connection, although they appear to have. In fact, inside the flat contact is not divided into isolated + - halves.

Yes having the possibility to use kelvin clips is really important with an lcr meter, especially if you're measuring small values.
I have a DEREE DE5000 for some years now and very happy with it.
I also have a mastech ms8911 tweezers and they are ok for simple ( and not small values) measurments, but the de5000 is better.
if you buy the de5000, buy it with all possible probes, it will be difficult and more expensive to get them afterwards

I have the uni-t UT622C. Got it for the 0.1V test level for in circuit measurements.
Every time I use it I'm impressed by the ohmic measurements (even with gold plated probes contact pressure matters).
Managed to trace the path of a low value inductor, something that is just impossible with a normal multimeter.
I replaced the clamps with the tips of multimeter probes for pcb measurements. Also got some hock adapters for probe tips to hold component leads.
