I've watched 2 different youtube videos comparing the readings on the DER EE against high-end bench equipment - the DER EE is insanely accurate

The DER EE has probe resistance compensation (4 wire and a bridge) so it will read a lower ESR which is more accurate than meters using plain probes. Having the ability to connect probes together and zero the meter does help.

That would be the most laid-back electronics video clip I've ever seen on KZread. Good to see that my "Silicon Chip" meter stacks up OK against some of the opposition.

I use the MESR 1OO and find it very good. No issues with it.

Three of the meters need to go trough calibration mode beforehand for first use. I got two of them. One is the MK-328 which in fact is far the easiest meter to use. Don't turn it on before you have the test leads on the subject. Just push the button and it's ready. It's is for the price very precise compared to my HP pro meter.

Thanks for the quick useful demonstration of ESR meters

You might already know this by now but capacitance is measured at 120Hz and ESR is measured at 100KHz hence why you were getting strange readings from the DER EE. The MESR probably alternates between the two frequencies but the DER EE does a lot more than ESR tests therefore you have to select the right frequency for the test that you are doing.

DENNIS N - I also changed the clips, I did a video on it too.

Good video. Would love to see more tests though. Testing a few good caps at different values would be interesting to show how accurate each meter is.

The DER EE DE 5000 is by far the best , read the reviews...

MK-328 is a sub-par clone version of the German OSHW AVR Transistor Tester project that can be found at mikrocontroller dot net /articles/AVR_Transistortester. English and alternate firmware support is available on the EEVBlog forum. The tester is not intended as a replacement for a LCR or ESR meter. It is just a ballpark figure. There is extensive documentation available through the official project forum thread, article, and SVN repo with a mirror of the SVN repo also available through github. The project was developed as an exercise in ultra simple hardware while pushing the limits of the internal hardware of the AVR MCU through a combination of C and Assembly. Basically this is the balls to the wall limits of an ATmega ADC. You can update the firmware or add project options for additional functionality ;)

How is it sub-par? It seems to be good enough.

The second tester from the left, I think you can just power it up by the TEST button, but you must have the leads connected first! Anyway, thanks for your videos! If you have the MLC500 also, can you compare it to the MESR100? Do you happen to have a REAL MANUAL for the MESR100?

What if you want to measure a capacitor that falls outside the given ESR table? For example, I have a 400volt 80 Farad capacitor in circuit. How would I test that one to make sure it is good using the MESR-100? Or, can it be done at all using this meter?

I have the MK-328, and for the money that I paid ($28 US on Amazon) I have been happy with it. It can test capacitors, as well as transistors (NPN-PNP-FET), diodes, & thyristors. The case is not the best, but I keep it on the bench. I believe the test frequency is 8 Khz. Amazon also sells a model without a case (model M28), that you could put into your own case.

The single frequency ones are 100Khz for the more expensive ones, and the really cheap uncased ones are 50Khz What you'll usually find is an 8Mhz crystal divided down to 100Khz - which was the original spec of the designer (probably because electrolytic capacitor manufacturers test at 100Khz) - don't know why some of the cheap ones are only 50KHz - but that is better for testing big electrolytic capacitors than 100Khz That DER 5000 meter is really good - has a variety of frequency ranges

Good video

Apart from the MK-328 who's frequency no seller lists in the specifications they are or can be set to 100 Khz - which is what capacitor data sheets test them at - i.e. the ideal frequency for smallish capacitors The DER EE is clearly the best one as you can select low frequencies - needed for accurately testing large capacity capacitors found in audio amplifiers The really cheap testers (usually without a case) use 50 Khz frequency and are inferior One you haven't got is a Russian one ESR-Micro v4.0 - shipped direct from Russia via their Russian language web site - but frequently not available - I'm getting one as soon as they have some more in stock - reputed to be best of the best In the meantime I'm going to try and find a UK supplier of the DER EE PS - that old cap likely needed a 1 hour charging voltage on it to bring it back to life, before discharging it and testing it - even unused but old stock electrolytic caps that have been stored for a few years need re-rejuvenating

Thanks for sharing this video but I don't understand why you turned off/on each time the instruments. It was frustrating.

yeah some prep is good, but over-preparation into the realm of lifeless/clinical is also pretty awful. thanks for the video .. helped me a lot.

I have the second one in too, it works but is crappy case puts me off. Good for fet testing though. The main ESR meter is the HP 4261a and a Racal Bridge.

Simon Spiers - I was looking to buy a decent hp lcr meter, but the prices put me off, the de-5000 was purchased instead as it does what I need and was a quarter of the cost. Yes the mk-328 works, but isn't the nicest to use, ok if your on a budget and just want something cheap that does the job though.

Those Chinese tester things do have a calibration routine, short all three test leads together and press test it'll ask you to run calibration. Also I found the grabber leads and not that great as they have a habit of oxidizing and the wire strands like to snap over time.

Why haven't you plugged the capasitor directly into DE-5000 slots? Or at least you should use TL/21 attachment with alligators instead of TL/22 tweezers.

great comparison..how about their inductance measurement accuracy? do they all agree to some degree?

It's actually measuring capacitive reactance. So frequency is ctitical. Most of these use a 100khz test signal..Alsobthe one on far right (msr100?) You need to zero the leads out..

If I'm not mistaken the DER should have had been set to 120hz to test that Cap, not 1khz plus you raised the Cap temp from holding it. I think that's why the readings differ so much between the DER and the other testers. But not a bad video.

Those two aren't enough to explain it. He simply didn't calibrate the instrument so he's measuring the lead capacitance/inductance/resistances as well as the capacitor itself...

A capacitor can develop high Equivalent Series Resistance (ESR), which is one indicator that the capacitor is on its way out, or currently kaput and needs to be replaced.

Won't a multimeter test a capacitor?

@trieck

A multimeter will test capacitance, but it will not test ESR, which is what this is all about.

The idea was good but surely you could have picked an electrolytic that didn't have rusty leads, checked the lighting, made sure that all the meters were working, zeroed them before taking measurements when required, and written down the results. Do a rehearsal before making your videos so that you don't waste your viewers time. That could have been a really interesting video but it was so amateurish it was painful.
