    Good comparison of the two testers. I prefer the DER EE DE-5000 lcr meter. For 100 bucks, it measures inductors and resistors as well. It also allows you to change the frequency to test the esr as per the cap manufacturer's specs. It comes with the short gator clips and long tweezer leads.
    Good video. Thanks for taking the time.

      Looks like a nice meter for the money, nice screen, I may just buy one for myself. I like the dual display ESR and capacitance, it's nice, but not necessary, our meters have capacitance measurements, I don't even check capacitance in the field hardly, ESR tells me if its bad every time. Switching test frequencies for our application is not a factor as looking up the original test frequencies from the manufacturer is not gonna be something appliance techs will do in the field, need to keep it simple. Really, just need to get a ballpark on the ESR, not military tolerance, lol. I like the two meters in my video because they have the chart right on the meter, on the 88A I don't even look at the chart hardly anymore, the LED bar graph tells me if its good or not, and the MESR-100 will tell you on the display if it's good or bad on the readout, but you do have to read it and figure it out. With the DE-5000 you have to refer to a separate chart, I'ld probably shrink and laminate it as it would get ripped up in the van. Thanks for the recommendation, though, I think for my workbench this would be a great add.

      Electronics Projects Yeah the DE-5000 is more helpful when experimenting on the bench. Either way good video.

      Thanks, just bought one, $110 on Amazon, $92 for the meter, $18 for the tweezers sold separately. It says 'meter only' hope it comes with a case.

      Electronics Projects Mine didn't but maybe yours will.

      No worries, I probably have an extra case that will fit it.

    Excellent comparison. Your banana connector rant is hilarious but so true. I got quite frustrated with the Mesr-100 when the cap voltage was obscured by another component that couldn't easily be moved. No problem with the 881. But then I had a bad cap that the 881 did not respond at all, didn't know if my battery was bad or my meter was faulty. Used the mesr-100 and then I saw 69 ohms which was out of the range of the 881. I know now that if it doesn't respond the cap is probably bad. I think having a readout like on the mesr 100 can be good in some situations but confusing in others. This guy found a use for that feature to test for shorts in diodes while in circuit since it can register miliohms.. may not be accurate but good for comparative testing/analysis. th-cam.com/video/z5JXm9jgLp8/w-d-xo.html.

      Good video, thanks for sharing it, I just diagnosed a monitor that had a shorted component on the secondary, was an 8 pin IC, dual mosfet. I was able to locate it in a similar fashion by using my bench meter, it has 1mΩ resolution, made it easier, also used my thermal imager to confirm the chip was heating up, as it was. I saw the video of the 'leak seeker' and I will tell you, you do not want to use that in a customer's home. The fluctuating beeping is super annoying, great fundamental design, but should have come with a headphone jack option.

      @@electronicsprojects4708 I’ve had a few leek seekers over the years and built two new ones in the past 12 months both from the “kit” version That’s available now.
      I just put a piece of kapton tape over the Piezo beeper inside. You can put multiple layers of tape over it until it gets quieter and quieter. Or you can put a little slider volume adjuster somewhere on the side of the housing. Also modified mine to work wirelessly from internal rechargeable battery.

      @@hullinstruments yea, I have put in potentiometers with both buzzers and lcd display to change brightness as well.
