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

Показать описание

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.

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.

Capacitive Reactance, and Inductive Reactance are the terms for AC measurements for capacitors and inductors.

At 14:33 don't you have that electrolytic capacitor wired backwards?

what are the readings of the small ceramic cap with a multimeter ?

good job, I'm waiting for the review, as I'm taking this meter for an LCR candidate.

Can this be used to measure battery like 18650 internal resistance?

Most excellent LCR video and they do have their place in troubleshooting. 😎 Thanks.

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.

can the UNIT ut 622e be used for on board testing?

Hello, inquiry: What voltage applies for ESR test on capacitors?

I almost got this UNI-T but ended up getting the DE-5000 instead after seeing a comparison someone did on youtube.

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.

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.
