kripton2035:
if you want you can build yourself a lcr meter with all these measured values : c, esr, d, q
here on my web site some free schematics

Just knowing a capacitance value (DMM or cheap C-meter) isn't sufficient to tell you if the part is any good or not. Just knowing the ESR is actually better but still inadequate to get the full picture. You need both numbers!

I agree. If you are getting an LCR meter, make sure it has that stuff.

Hey Dave, Can you do a review on the Agilent LCR Meter vs others. I am contemplating buying the new one that came out (Not sure if you got one of those to review) but I do know you had several LCR meters sent to you and I haven't seen a review on the others/shootout.

It would be really helpful as I'm starting to do a lot of work with inductors and RF.

Thanks!!

Respectfully,
MajorEE

The EIT labs LCR meter is on the UPS truck.
The new Agilent one I have asked for and am waiting for a response.

The IET Labs meter is made for them by DER EE, in Taiwan.  I contacted DER EE about the meter, and they referred me to IET.  Here is their product link:

My concern on IET Labs DE-5000 is mentioned by robrenz from another post
"The main chip has an epoxy smear to cover the identification" https://www.eevblog.com/forum/index.php?topic=4909.msg65652#msg65652
It is possible the epoxy may cause reliability issue in the future   ???
