hi martin, recently i bought a ut61e, thanks for your review, i discovered something, if in voltage AC you push the yellow button, you can see the HZ but if you push again the yellow button, you can see the duty cycle, push again the yellow button and come back to voltage measure. Check it. And with the tester probes, i was polishing the metal part with a dremel accesories and goes much better, it is how your fluke probes. You must try this. Greetings from spain.

I just want to state that I have been using the UT61E for the last several years for amplifier reconditioning and other general electronic work and it has been more than adequate to the task. Sure I would like to have a better meter, but I am retired and my budget jut won't permit the purchase. Anyway the UT61E got the job done and I am glad to have it! Martin, I love your vids.

Hey Martin, After reviewing your entire review I purchased this Meter and it came with both Chinese and English manuals. With my Fluke leads the continuity test is not scratchy at all. Seems to be an awesome meter. It is replacing a tpi153 4000 count meter in BluePoint (Snap-On) in which the mA setting no longer functions (friend borrowed it and blew both fuses but still inop after replacement). Lesson learned no meter loans. Also 10 years old so it did well but getting iffy even with good leads.

I can't get the D-Series of the multiumeter to work at all with MultiDMM. It seems like there is a software problem, when im adding a gauge the program shows a program error message. And when i try to add the meter it can't find the device (Using the USB not COM) And i have tested it works perfectly with the software that came with the device.

Hi Martin, I enjoy all your videos as they are quite thorough and educational. I'm not too excited about torture testing as it is sometimes quite easy to blow a meter. Blowing a meter is entertaining if you really give it a bang, but the capability that separates this and similar meters is the collection and display of data. Nobody on YT is really addressing that, and you've just touched on it. I'm interested in logging the performance of battery charge and discharge performance. There is so much research on battery chemistries as of late... Collecting, manipulating and graphing the data is a strength and an growth among inexpensive DMMs. I hope you would cover the capabilities of different software that comes with or is used with DMMs, their applications and improving the accuracy of various DMMs. Keep up the great work. I will look forward to the next, and the next, and...

Thanks for the review, especially for showing it next to the ms8218 and the agilent, I thought that was interesting. I would be interested to see if the meter could be calibrated a bit in pt. 3. The overshoot issue seems like it would be a deal breaker, wouldn't it? I'm just getting started in electronics, but it seems that not being able to trust your measurement device to detect voltage spikes, would be a problem?

@sailorbob74133 7 жыл бұрын

Is the update rate achievable on the software faster than on the dmm's display? I was hoping that I might be able to use this to back probe a camshaft position sensor on a car and log via the computer how fast it's switching. At 600 rpm it should switch briefly from 4 to 8 volts about 10 times per second. Of course I may just have to break down and get a cheap automotive oscilloscope.

I like the ut61e, but what I bought does not correctly measure the duty cycle in the voltage range, it also did not measure frequency of 18Vrms in the frequency scale, it should measure up to 30vrms according to the manual. I made a video with these problems on my channel and when I was shooting I had a problem in peak measurement as well. Are these problems common, or did I buy a multimeter wich problem?

please do the torture test. I think the temperature drift and general measurement stability is one of the main factors that separate high quality meters from bad ones.

It's still good to see how it responds to real world conditions. I take my Flukes out and about for work, and we get 35°C + here - what would happen if I took a Uni-T with me instead? You have a good point that this DMM should probably not be used outside of a lab, but I still think there is merit testing outside of specs. If for nothing more than curiosity.

This meter has enough accuracy for stable, low frequency signals. But is it also suited to measure audio signals with high crestfactors? Note: The Operating Manual gives a freqency response up to 1kHz only for AC Voltage measurements! Next I cannot find anything on crestfactor.

I made the same mistake with the HZ setting, but with 400V AC. It blew the meter. Resistor measurement now constantly displays 220 ohms. Voltage measurement seems still to work. So, be careful!

My leads were terrible too. Cleaned them with alcohol and a soft cloth for a while and they're okay now. Still not good, but they work right at least. Curious that mine was low in readings about the same amount as yours. Was able to calibrate DCV, but ohms and most other ranges don't have adjustments. I would be curious to see the approximate tempco, I think it will probably be a weak spot for this meter, it didn't seem very stable in my testing.

@mariushmedias 11 жыл бұрын

The update speed is 2 times per second, and the graph at the bottom is 20 times per second. It's kinda slow for checking voltage spikes, the agilent ones would work better for that. With this meter, you'd also use the data logging feature, and you'd see the spikes then, and you'd be able to easily exclude the erroneous readings then The "overshoot" seems to happen at range thresholds; 220mV, 2.2v, 22v etc and it only shows up for 1-2 readings, or 1s.So easy to exclude them from the measurements

Been watching as many of your videos about multi meters as I can as well as many others and I am still lost. I purchased 3 meters and not sure if I am happy with them or not as this is all new to me. If you would buy a meter for iPhone repair and other micro electronics around $150, which one would it be? I rather invest into the best one now and have it for a long while then save money and lost in the long run.

Hi Martin, the voltage accuracy tests you did was with the uni test leads. Did you try the fluke leads to see if any better accuracy could be obtained. Also imagine you had a workshop with 10 engineers and gave them Fluke 87v meters that could cost you over 5000 euro where the uni Would cost you 500 euro. Enjoy watching your videos keep up the good work. Big thumbs up.

roy douce Thanks again Roy. For these tests there would be little difference between the Fluke or other leads. But at some point I'll do a review of test leads to see what the differences are.Cheers, Martin.

@mariushmedias 11 жыл бұрын

I took a regular handkerchief, dipped it in alcohol (ipa) and rubbed the leads in it.. no problems from that point. The only flaw I see is switching to AC when on higher DC voltage, but if you work with the meter as a normal person does (remove probes before switching) this wouldn't be triggered

@10:37 The Mastech MS8218 is 50.000 count with 0.03% accuracy and priced at 170$ The Agilent U1272 is 30.000 count with 0.05% accuracy and priced at 380$ Uni-T is 22.000 count with 0.1% accuracy and priced at 55$ So spec'ed at 2-3x less the accuracy and at least 3 times cheaper, and it's within spec. A 55$ meter would be 8000 count at best, so you'd see 15.99 in the best case scenario... same value you get if you round up the last digit.

Peaks on voltage seems to be when it autoranges to another scale, ex from 2.2v to more, or when going from showing 5 digits to 4 digits, and so on. It's almost as is if the dot on the display is read incorrectly once when the on screen digit amount changes ex you raise voltage and meter changes from 22.140 to 22.350 ... the meter sends 223.50 once. Doesn't look that bad to me, it's just 1-2 measurements max. so they wouldn't affect the logging that much.

Hi Martin, thanx for this review, as i need another DMM, so this is a good help. As in first place i thought this one is one to go for, but...no...no way. A usable DMM should be able to at least manage beeing switched between its positions while conneted, as i do this usually on/with all my meters. So this one is out here. As i go with your video, it seems to me that they put this one out in a rush or some like, as for me its software seems not finished, but that´s probably common nowadays, as this it truly a huge cost factor.

@KeenanTims 11 жыл бұрын

Apparently DC isn't blocked in AC modes and the meter goes screwy (I can't test the current ranges for this). It should be possible to measure how much AC there is on top of a DC bias (this is how an ACV range should work), but it seems this meter can't do it. Mine behaves the same, even if I set AC first. Mine is also only good up to 100MHz on frequency (spec says 220), at ~4.5Vpp sine. It does say amplitude unspecified for > 40MHz, but larger than 4.5Vpp is a bit much to be reasonable.

I beg to differ. Leads play a large role in accuracy. I do not understand what you mean by sliding the leads against each other. Do you mean when he is quickly skimming them together?? If so, this is testing the speed or update time. Sometimes I must use an analog meter if speed is needed for what is being tested.

Yes, the much better UT61D with the slow continuity, capacitance measurement times in tens of seconds, etc. The chipset in the UT61E is far superior. Using the relative function does not change the resolution of the meter, and the UT61D simply does not have the same resolution.

gee-whiz if you could take two of these meters and make a dual trace display software o-scope this would be a nice high voltage opto-isolated o-scope that would be a hobby budget version of the expensive fluke scopemeter. yes it would be low BW but have great channel isolation for 480vac 3phase 60hz SCR motor drives... $120 compared to $2,000 stuff...Mmmm...:/ thanks

I also have a set of Probemasters and they really are amazingly high quality and well worth the money, they can make even the cheapest meter work better than it has a right to.

Can't test mine unfortunately, don't have anything to compare to Yes if it doesn't take a lot of time, please do the heat test, but mention in the video the temperature ranges the meter is rated for. It would be bad imho to flaw the meter from (possibly) going out of spec at high heat when the manual and specs say it can't handle that high heat

@DanFrederiksen 11 жыл бұрын

btw, what type of contact you get from sliding the leads against eachother is spectacularly irrelevant. so buying different leads is not a good investment at all. they work perfectly fine, you wont get more accurate measurements at all.

@mariushmedias 11 жыл бұрын

The UT61D is inferior. 61E is 22000 count, TRUE RMS, fast continuity, fast capacity, data logging, as low as 0.1% accuracy compared to 0.3% or something like that for 61D and the others in the series. It doesn't even matter that it's close to the accuracy limits, other meters at this price range have less accurate %'es. Simply put the two models are totally different and even with the minor flaws (issue with dc voltage when on ac reading, dirty probes), it's a meter with great value for money.
