looking to buy lcr meter what are you options on brands

<< < (3/5) > >>

rhb:
I now have a BSIDE ESR02 Pro, Peak LCR45 and ESR30, HP 4284A and 8245A.   I've measured the same part on them and my conclusion is this:

Unless you are old and have more money than time to spend it, get a BSIDE ESR02 Pro and keep the rest of the money in the bank. There will be another piece of kit you'll need, much sooner than you think.

Have Fun!

Who would very nearly have killed for a BSIDE when he was in grad school 35 years ago and trying to build a DC 40 m receiver.

Recently bought a DE-5000, and have a BSIDE ESR02 and a home built ESR meter from Elektor magazine.
Measured some random capacitors, with the DE-5000 always set at 100kHz just to match the test frequency of the Elektor ESR meter.



Since I still don't have the proper test leads for the DE-5000, TL-21 or TL-22, I used short alligator leads. The list does not intend to be accurate, and should be observed just for guidance. And note also that for big capacitors would be more realistic to have set a lower test frequency (100 or 120Hz for the real big ones). The measured values were more to compare the DE-5000 to the Elektor ESR meter, and not so much the ESR02. This one tests also semiconductors. For general purpose, the BSIDE ESR02 is very handy.

rhb:
Would you please label the rest of the spreadsheet columns and add the capacitance values.  I assume the values are ESR, but it should be labeled that way.

My comment was directed at the measured LC values, not the ESR which is tough to measure well.

I'll try to test a couple of parts on the BSIDE, LCR45, ESR30, 4284A and 4385A and post them.

We live in a golden age. Old, top of the line T&M kit is cheap.  A $500K mid-90's state of the art lab can be had for $25K and a comprehensive basic electronics lab can be had for under $1000.  30 years ago LCR measurement and semiconductor test for $20 was inconceivable.

Have Fun!

For electrolytic type, even they're polymer type that can withstand high RMS current at high frequency, to measure the capacitance, "always" set to 120Hz, as its the de-facto standard frequency for measuring the capacitance at most electrolytic caps datasheets.

While for series resistance for electrolytic, "usually" most capacitor manufacturers used 100kHz.

Otherwise your captured data there will become meaningless.

BravoV:
Suggesting DE-5000, regarding it's accuracy, while ago at this forum, we did a comparison on my Mastech MS-5308 (this is equivalent to DE-5000 as they're using same Cyrustek chip-sets), against a 5 digits US$ priced Wayne-Kerr LCR meter  :o, and here are the results.

For it's price, I would say the Cyrustek based LCR meter is quite impressive.
