What Is An LCR Meter? Uni-T UT622A First Look
ฝัง

- It dawned on me that some people don't know the difference between a multimeter and a LCR meter, so I figured it would be a great first look at the UT622A to explain what a LCR meter is and to take the UT622A out for a spin!

My first time seeing a LCR meter in action, and I am pretty impressed.
good job, I'm waiting for the review, as I'm taking this meter for an LCR candidate.
Most excellent LCR video and they do have their place in troubleshooting. 😎 Thanks.
If your resistance test box shows correct percentages, then the LCR meter is less accurate. For example, on the 100R resistor it shows 0.01%, so the value should not exceed 100.01 Ohms, but the meter shows 100.05. But, granted, the LCR meter probably meets its claimed spec of 0.2 percent accuracy or so.
Thank you very much
Excellent Review .. Thanks a lot
Capacitive Reactance, and Inductive Reactance are the terms for AC measurements for capacitors and inductors.
I got that far before my brain said "yeah, not tonight man"
what are the readings of the small ceramic cap with a multimeter ?
I almost got this UNI-T but ended up getting the DE-5000 instead after seeing a comparison someone did on youtube.
Are those buttons as irritating as I've heard?
Did you null the meter out before doing the measurements ? the lead resistance at the end there was a bit high, wold have given even better resistance readings otherwise.
I did not, the manual for this thing is huge lol
Good reminder.
When I zeroed mine it made a noticeable difference (I assume mostly based on the stray reactance in the leads)
Very cool tests. I'm sure that review took a while to do. I'm kind of curious if that micro usb outputs anything and does more than just charging. I feel like it might.
Hello, j’aime bien cette marque 👍
Moi aussi! J'aime bien Uni-T, ils font des bons outils!
Can this be used to measure battery like 18650 internal resistance?
Hello, inquiry: What voltage applies for ESR test on capacitors?
can the UNIT ut 622e be used for on board testing?
I'd like to see an accuracy comparison between the really cheap LCR meters and yours. I bought a super cheap one off banggood for about 10 bucks and then a slightly nicer one for about 30 bucks. I'd like to see if the accuracy is much poorer on the cheap ones.
I'll see what I can do, thanks for the suggestion!
There are some comparisons on youtube. Youll be surprised at how good even the cheap ones do..
I bought my multimeter from Canadian Tire. 😁
It takes multiple measurements, it's a multimeter...
Could you do a side by side comparison of the UT 622a versus the Sanwa LCR 700?
I would love to, if I can get someone to send it to me, I'll do it.
Can I measure the LCR of NFC tag?
I can't see why not?
At 14:33 don't you have that electrolytic capacitor wired backwards?
It uses AC to test, so polarization doesn't matter
@@SimpleElectronics Interesting. So why does polarity matter in DC but not AC?
❤
thank you sir but the real question is that we can test the components on the pcb without removing
To me every LCR meter should do ESR as well.
What's the maximum capacitance it can measure?
Stats for the UNI-T 622A
99.999mF @ 100/120Hz, 9.9999mF @1kHz and 999.99uF @ 10kHz. If you get a C or E model it can do 99.999uF @ 100kHz also. 0pf is the minimum for all frequencies w variable amounts of trailing zeros.
@@arsenicjones9125 I've seen the specs, but I was curious if someone really pushed it to the limit to see if those are real and accurate
08:55 - LOL. Better uggly and smart than cute and dum :)
It's not a multimeter
