TA-0415: ZOYI , ZT-MD1 - LCR Bridge Tweezers - Hands On

[@zotekmultimeters4774]

Well done! Thank you so much for the wonderful review!

[@TonyAlbus]

Thank you!

[@HainjeDAF]

Nice simple device. Great help if you're working on a (smd) project. Being over 50 and colourblind, such a device beats looking up color bands or reading fineprint on components Thank you for another good video. Hope you survive in the attic. We're at 29C 60% rel.H. in Noord.

[@TonyAlbus]

Thank you !!! Jeps lekker warm :)

[@yannis92preloude]

Hello Tony thank you for your video demonstration. Just placed an order yesterday based on your video it's not a bad tester it's pretty good quite accurate for its price. A little bit of a disappointment in the diode test for LED lighting up but nevertheless it's not a problem.

[@TonyAlbus]

Thanks! Yes the 1 Volt is low for LED. for its price well done

[@pault6533]

OK well just that quickly they rolled out v1.7 to address a few other things Update details: 1. Added the functionality to save and export measurement data. 2. Improved the accuracy of low resistance measurements. 3. Corrected spelling errors in English words I'm excited to give it a try. #1 seems really cool!

[@TonyAlbus]

Thanks!! where do you get your updates? .. zotektools still has older i think The FNIRSI can do the export, so they had to i think.

[@pault6533]

@@TonyAlbus See my post on EEVblog forum for this.

Hi Tony, I'm Left-handed Right-handed - I can do everything with both hands - it's a pity that the image does not change in AUTO mode with the position sensor. Looks very good, I will probably buy one (when I have money to spare) 😁 Nice day 🙂 Tom

[@TonyAlbus]

Thats is a nice idea, position sensor, but than you need to be able to switch it off too... like ipad/iphone.. depends also on you working position at that time.. hanging up-side-down, you dont want the display to flip on you :)

[@Edisson.]

@@TonyAlbus Well, of course, I probably wrote it wrong, I meant, in addition to manual control, the option to turn on AUTO mode.

[@davidv1289]

Thank you for the review, Tony. I like the lefty righty feature - someone was thinking. Looks like it would work well on through-hole boards too - for us old farts stuck in the 60's. Regards, David

[@TonyAlbus]

LOL... Thanks David :)

[@tonogtube]

Another multimeter in my collection? 😀

[@TonyAlbus]

You can never have too much of them :))

[@ssalient]

There is no such thing as having too many multimeters.

[@heinztimmer5453]

​@@ssalientit's an costly addiction 😅

[@snabelsvin1]

Good form factor on that meter. Maybe do a teardown? I'm interested to see whether it has input protection and can handle a charged cap. And throw those China capacitors in the trash. Capacitance way below spec, high ESR, leakage current trough the roof and can explode even under rated voltage. They're not worth the time and effort when quality caps isn't that expensive.

[@TonyAlbus]

Yes you are right about the caps... what a disapointment.

[@pault6533]

Go get your version 1.6 firmware, improves resistance readings in the megohm range🌞 Doesn't affect calibration stored in the unit or your favorite settings.

[@TonyAlbus]

Thanks! i did not know yet, great!

[@TonyAlbus]

Thanks Paul, i added the links to my video description

[@tcirit]

I bought Fnirsi's LCR-ST1 and waiting to test it. I think that its specs same with Zoyi's. Thanks for the review.

[@TonyAlbus]

Thanks for sharing, in about two weeks i will have my FNRSI too, i cant wait..seems nice too

[@tcirit]

@@TonyAlbus Great news! I will be waiting for your review, thanks.

[@stoptheirlies]

Hi Tony thank you for the review, what does the "D" display mean on the Capacitance range please.

[@TonyAlbus]

While all LCR meters offer readings of inductance, capacitance, and resistance, higher-end meters will also provide additional measurements. These options typically include impedance (Z), phase angle (θ), conductance (G), susceptance (B), dissipation factor (D), quality factor (Q), and equivalent series resistance (ESR). D or Q: D is called the dissipation factor and is the real part of the impedance divided by the reactance (the imaginary part of the impedance). Q is called the quality factor and is the inverse of D. When D is very small (or Q is large), the component is essentially a pure reactance.

ESR on Capacitance Range Tony: Can the unit display ESR when measuring caps? If so, with larger electrolytic caps (say >1000uf) does the measurement frequency need to be reduced to 100 Hz, or can it measure ESR at 1KHz/10KHz? Very nice review, Thanks

[@TonyAlbus]

Bigger Caps you indeed need to lower the frequency by hand.

[@pault6533]

Rs on this unit is equivalent to ESR on other units. It works good for >1 uF. 100 Hz is what you want for E-caps. D and Rs is rather inconsistent for for small non polarized caps.

[@TonyAlbus]

@@pault6533 Thanks!

[@Homer19521]

Maybe I missed it, but how do you vary/select the test frequency? Looks like it offers 3.

[@TonyAlbus]

Oops, yes i did not show that. easy, the Left or Right button

[@Edisson.]

@@TonyAlbus The different frequency could have influenced the different results with the LCR meter 🤔

[@TonyAlbus]

[@johnwest7993]

They are particularly handy for hobbyists for checking SMT components before they install them, as well as for comparing 2 identical circuits such as channels in stereo amplifiers, since each device tested includes all of the same interconnected components. So whatever the tester reads merely has to be the same for both channels. It makes zeroing in on the problem portion of the circuit very quick. That doesn't matter all that much for hobbyists, but for repair techs the speed matters a whole lot.

[@TonyAlbus]

Thanks! yes good point!

[@pault6533]

Zener diodes? What is the Voc and Isc? Thanks Tony!

[@TonyAlbus]

I don't think it will, with its only 1 volt

[@pault6533]

@@TonyAlbus OK I see that now. Do you think they will fix the spelling of "Languege" in the next firmware update? Did you get the extra set of tweezer tips? Are they the same (a spare set) or different (different shape)?

[@TonyAlbus]

@@pault6533 There is a posibility to do firmware updates, so that is a good start, if they will is not on me. usualy i show everything i got from them, if you did not see it on video in teh quick unboxing ,i prob did not get it, i do not remember.

[@lohikarhu734]

Tony, there's no reason, at all, why an LCD can not be used in either hand, since, typically, the bit map display is software driven, and even in Arduino, easy as pie to "flip"

[@TonyAlbus]

Classic LCD has fixed 7-sigments for numbers and some single bit for the 'signs' ... for bitmap driven lcd this should indeed not be a problem. but why use that if you have now OLED
