This will be the last T4D for a while so we can jump into reviews, tutorials and projects.
I also give a final tour of the lab and equipment that is due for review.
I do an overview of the UNI-T UT612 LCR meter and compare reading with my Fluke 8846a and Agilent oscilloscope.

I like your detailed reviews that leave no stone unturned. Great work. I also like your solution to the ones who want you to be someone like them. Don't change.
With all the great info you give, the way you teach and the journey you take us on, your videos can only be to short! :-)
Excellent Martin. Not to long by any means. I'm an older retired EE and find your lectures to be very helpful for me to catch up as it where.
I'm actually thinking to pick-up a UT612 based on just your short initial review on here.
Thanks and I will continue to "tune-in".
Good point..I must look into that. Thanks for your post.
Always very entertaining and informative. Love your channel.
Yes...I have this in a list of meters I'm considering for review. Thanks for the post.
Martin, I think the length of your vid's is the reason we watch them!! I like the time and detail that you put into them. Thanks for that, TDB3
Thanks for that Sam, I missed that in my searching...and I see it has a nice range of test voltages too. Noted.
Cheers, Martin.
It's not possible for your video's to be too long. The way that you present them is perfect in my opinion. Thank you.
I like your long & detailed videos
Thanks for the advice.
Thanks! I like it!
Thanks Bill.
Thanks good man...I might just film the "fix"...
Cheers, Martin.
Hi Martin, love your your videos, pls review the Unit 195 ds seems a good dmm. Thanks
nice work bench!!!
Can you test in-circuit with it if it has ESR?
Great again,
Nothing wrong with the length of your video's..,I agree with Bill McKibben. You have a very good teaching style. Many thanks I enjoy them.....
Mike
Bkk
Yup...I think I will post a video when I fix it...
I still have some of your other ideas parked...I'll add this one...just grant me one more life time to get through everything...
Thanks Sean.
Naturally I was talking about the oscilloscope measurement you did.
Anyway: good work!
It would be awesome to see you diagnose and repair your DIY load.
Thanks Martin. What do you think is best for testing caps in circuit the uni-t 612 or the peak esr70?
Nothing wrong with the length of your video's, I just make sure I dedicate time to watch your video's.
i have that very same lcr, nice to see it's at least pretty accurate as i dont have anything to compare it to, except a cylindrical 100 turns air inductor i made which gave about the same value both on paper and on the meter, i suppose the error is mostly from the the not perfect cylinder and humidity (above 70% most of the year) but still within 2%.
I always watch videos at 1.25% faster speed. UA-cam has the option to speed up the video as well:-) Great information, Thanks!
nice t-shirt!
When taking the measurement of a 1.8kohm resistor, the value is 1.72kohm in the ac resistance mode and 1.81kohm in DCR mode. Does it means the equivalent parallel inductance is much higher than the equivalent series inductance. Or the UNI-612 is only display the real resistance term and not the Z impedance when the testing frequency is at 1kHz.
Hello. I have one question. Could I do in-circuit ESR measure with this UNI-T meter? Thx for reply.
Possibly.
if there're no parallel components. resistant drop when there's multiple impedance in parallel. if same concept as resistor applies. If not mistaken.
I love lengthy videos (I've subscribed to W2AEW anyway because of the great content, thanks very much for sharing), could you suggest other UA-cam channels like yours?
Hi, Martin, would you recommend Mastech MS5308 over this UNI-T UT612?
I would recommend DER EE DE-5000 LCR Meter over both of them.
Can you share the Mastech review link? I could not found it in video links.
As well Martin should look at Free Electrons fast pulse generator, really nice device. Really like the Cure shirt there.
What happens when u change frequency to 100kHz and then check capacitor? It shows no reading on mine .. everyone are saying they are testing on 100kHz but mine shows OL.. please help, is mine ut612 defective?
for that amount of money i would prefer to hack and old used fridge into a coolbox, if it works with computer, i'm sure it could be done to a coolbox, it should reach at least -15ºC, although ive seen cpus get to -26ºC so somewhere between that
Hi there , when are you a gone tear down the UNI-T UT612 LCR ,please let me know , i want to purchase one of this LCR meters ? Very interesting to know if is using 4 wire test probe .
Other question is , you know something about the DER EE/ DE-5000 LCR meter ?
At 44:41 Uni-T LCR meter is set to Rs (serial) mode but measurements must be on Rp (parallel) as on Fluke?! 0.387k shown on Fluke maybe can be show precise result if you set Uni-T LCR mete on Rp mode?
Maybe for safty you could run a Flex tube for the fan for the safe out the window, and set a outlet inside the safe for plugging in stuff, instead of having to cut its cord, Like the small Heater. Just a Thought :)
Martin your video length is always fine by me, Nice to watch an in-depth explanation of the things you do.
P.s do a video on the dummy load fix.[iminent=7pQ73AgUWfOB]
When you measure capacitance the frequency of the square wave doesn't matter because you're measuring step response. You can use slow square wave as you desire. What's matter is the rise/fall time of the input square wave compared to the exponential response of the circuit.
Jump to minute 32:13 if you're here for that UT-612 overview. Or just buy the DE-5000 if you're looking to find the best one.
How do i measure capacitors. 1000 Hz or 100 Hz .
what is bar graph for
Nice bench.
what camera do you use?
Thumbs up for The Cure.
Canon HFM52...and Sony CX130...
No problems with video length on this side. Sometimes I pause and return after a while, simple as that. Go go giveaway! :-)
can't find w2ew on youtbe
42...I like that :-)
I do enjoy your videos, long and short alike, but I've always thought that while you are a good narrator and teacher,when you're struggling with a concept, I feel the videos can drag on a little bit with facts and a lot of "um's". Although good, I think you could still always improve your presentation
You should review the Agilent 1250-series, I've just ordered one, and I think they're a valid competitor to the Fluke 87. particularly the LCD version since there aren't any good reviews I know of
I believe the Peak ESR70 would be better for in circuit testing. There is a gent on my forum called retiredcaps...chat to him or go to badcaps.net and see what they say there.
Electrolytics are often +/- 20% tolerance, sometimes as much +50%/-20%, so I wouldn't expect exact measurements.
Tip or Thought for the Day...just an easy chit chat, news, review session.
I had Read the " make them shorter" if that is what a person want then the answer is 42. (hope they"ll get the referance) if they want more details do your own research. and dont rely on others. Little Rant :)
For small caps down to about 10pf, try this tester, here's a demo. ua-cam.com/video/xNG2-4pbhQU/v-deo.html Oh and it does much more, and receives rave reviews. Ebay
a fire extinguisher will not put out a lithium battery fire
The critics that say your videos are to long and often off topic.Fine iff you dont want to change the way you present things you get few that bother to look at the whole video.Just look at your likes.they are not great on this video.
3000$ for a peltier cooler that goes down to 15c? no thanks :)
that's probably the most pathetic device I've ever seen
I found this very funny (absurd) You are struggling with high school stuff, and walking around in "the lab" in your bare feet...
You see mjlorton, so of us are very much observant we are NOT just dumb Engineers. We can NOT just be fooled by you slow voice. You are Pausing the video before comparing you LCR meter and the scope value. You will fool fools NOT us. I am a Mathematician, Scientist, Engineer and Philosopher. I can NOT be fooled so easy.
