Good multimeter but will need a modification.
4 out of 5 stars
Good multimeter but will need a modification.
Very good multimeter but will require a modification.Upon arrival of my UT61E it needed recalibration.My voltage references are a 10.0000 Volt reference designed by VE2AZX and based on a Texas Instruments REF102C and my second is a 5.0000 Volts of my own design and based on a MAXIM Integrated MAX6350 (both buried Zener devices) and are correlent to eachother....Sorry, for now i cannot afford myself an LTZ1000 reference !!!Upon reception of the UT61E, it was off by -4 count on 10.000. Later-on after a first calibration, it was off by -6 count again.After inspection, i found the guilty part: The DC calibration trimpot (VR1), a 1000 ohm trimpot of questionable quality.After unsoldering / measuring its value to 528 ohms, i ordered a high quality (Bourns) 50 OHM trimpot along with a top quality (528 - (50/2) ): 500 ohm fixed SMD resistor.The 50 / 1000 ohm reduction ratio narrows the trimming range by 1:20 making the UT61E's calibration waaay smoother and the addition of a fixed resistor is a net plus in stability.I then cut and tinned a trace between VR1 and a close resistor, R16 and soldered the series fixed device in place.Since then, nearly 6 months later, the UT61E remains rock solid on DC calibration.Before you repeat my modification, carefully measure your VR1. Mine was at 528R, yours will probably be different and you will have to choose your series resistor in accordance with the goal in mind being having the multimeter calibrated on VR1's midrange or close to it.Otherwise, the multimeter is well built for its price. AC / DC volts use a precision integrated resistor pack with carefully designed HV cutouts.BTW: The UT61E has an "all-in-one" 22000 count multimeter IC (ES51922 by CYRUSTEK, a chinese manufacturer.) with integrared voltage reference.After checking at Digi-Key, you may go even further with a 20 ohm trimpot. They have them in stock.========================================================= (Français)Très bon multimètre, mais, idéalement requiert une modification.A l'arrivée, mon UT61E avait besoin de calibration.Mes références en tension sont une référence de 10,0000 Volts conçue par VE2AZX et basée sur un REF102C de TI, et ma seconde référence est une de 5,0000 Volts de ma conception et basée sur un MAX6350 de MAXIM Integrated MAX6350 (Les deux de type "Buried Zener") et sont corrélentes l'une avec l'autre....Désolé, je ne peux pas encore me payer un LTZ1000...Sur réception, mon UT61E était -4 sur 10,000 (9,996 V). Qqs semaines après ma calibration, mon UNI-T était "off" par -6 !Après inspection, j'ai trouvé le composant défectueux: VR1, un trimpot de 1000 ohms de qualité douteuse...Après avoir mesuré VR1 (à 528 ohms, dans mon cas), je me suis procuré un trimpot de bonne qualité (Bourns) de 50 ohms accompagné d'une résistance fixe de haute qualité de ( (528 - (50/2) ): 500 ohms, dans mon cas.Cette diminution de 1000 à 50 ohms réduit la gamme de calibration par un rapport de 1 / 20, rendant la calibration nettement plus facile et l'ajout d'une résistance fixe augmente grandement la stabilité du multimètre.Reste à couper la trace entre VR1 et une résistance voisine, R16, étamer et souder la résistance fixe en place.Depuis cette modification, l'UT61E est devenu parfaitement stable à 10,000 volts. Cette modification est un net plus pour ce multimètre qui demeure un excellent instrument pour son prix. Son module résistif de précision et ses "cutouts" pour tensions élevées sont des caractéristiques intéressantes.Avant de répéter ma modification, mesurez avec soin votre trimpot VR1 (après l'avoir désoudé). Vous devrez vous procurer votre résistance fixe en conséquence. Optez pour une résistance avec tolérance de 0.1 % ou mieux.En passant, l'UT61E utilise un intégré "tout-en-un" +/- 22000 (ES51922 de CYRUSTEK, un fabricant Chinois) avec référence intégrée.Après vérification, Digi-Key a des trimpots de 20 ohms. Une alternative intéressante.

I received the RioRand UT61E digital multimeter in less than 5 days which was a pleasant surprise. RioRand is a great distributor and packages the item very well.
I checked other more expensive meters but decided on the UT61E because it is a great bench meter for the electronic hobbyist.
No need to have a $400 meter just sitting around collecting dust.
The speed of the display is very quick and I am impressed with accuracy when checking volts, current, ohms and capacitance measurements,.
This meter does not have auto power off or back light capabilities but that is not a big issue for me. There are sites on the Web that show how to add back light and auto power off capability if so desired. One of the reviews showed that when the meter is set to read low resistance and the meter leads are quickly and repeatedly shorted together, the audible beep does not always sound. My leads did not have this problem.
The one feature I liked is the hold feature where you hold down the 'hold' button, make a reading without having to look at the meter and when the meter beeps again, you have captured the reading.
So for the price of this meter , $50 USD, I am very satisfied with what it can do.

Working great so far, lots of good features for the money. Not mentioned anywhere in the manual is that the 'E' version of the UT61 has an auto hold feature on it.

This review talks about the feature at the 1:04:25 mark (and is a very useful and thorough review in general if you're looking for a multimeter in this price range): [...]

4.0 out of 5 stars I love this multi-meter except for the probes

I love this multi-meter except for the probes. I really feel like it belongs on the bench with my other gear. Although I am sure there are safer options when working with AC, I will be working 24volts DC and under.

Pros:
Solid construction.
Rotary knob feels really nice.
Accurate, reads the voltage bang on compared with my oscilloscope.
Rubber protrusions keep the meter in place nicely, even when upright using the stand and turning the dial or pressing button.
Has auto-hold function (hold down the hold button)

Cons:
Probes are not great, even with light sanding, poor results when using Continuity test mode. I swapped it with some other probes and the meter itself does a fine job on the continuity with the replacement probes (Extech)

Display update speed of the actual numbers is slower then expected, but this is a minor complaint.

Good quality Item,Best bang for your buck.

After researching a lot on a budget digital multimeter (DMM) I found very good reviews about this item, also there are some people that have made modifications to it to add a backlight, auto shut off, and other things that come integrated but are not implemented. So if you like to hack electronics, then this is a must have tool in your arsenal and you can hack it too if you want.
I haven't used it to its full potential, but so far it has been a good tool for my uses that sometimes include fixing SMD boards and common electronics.

Please look around the net to find intensive reviews about this digital multimeter. you wont be disappointed. and at around 50 dollars is not expensive for the capabilities it has.

5.0 out of 5 stars Good Quality/Features/Price ratio

The decision to buy this multimeter was based on a Youtube video from mjlorton’s page. He made a very comprehensive 4-part review on the UT61E (and other excellent videos) and the end result was a very positive quality/price instrument.
The 22,000 count is a very useful feature that I really like and couldn't find in other DMM's around the same price range. It feels sturdy to touch (the rubber actually has a nice smell to it) and the app to a windows machine is a neat added feature.
Some may find the lack of a back-light could be an issue but the screen is very clear, so, it seems to be better fit for electronics bench use in a well-illuminated environment.
The leads are not fantastic so consider adding Fluke or Amprobe silicon leads.
While durability and life-span remain to be seen, I give this product a 5 star rating.

3.0 out of 5 stars Nice meter for electronics measurements but beware of likely bogus CAT rating.

If you need an inexpensive 4 1/2 digits multimeter for general-purpose measurements, the UT61E is difficult to pass up on.

One word of caution though: many variants of the UT61 (like the unit I got) lack input protection and will cause the meter to fry itself in case of high voltage transients or when fuses blow on inductive loads while measuring current, so you might want to be extra careful when making mains voltage or inductive load current measurements.

Excellent performance, functions and accuracy for the price. Only issue was the tips of the leads which out of the box conductivity is terrible because of a coating or cleaner they use in the manufacturing process. I used a little high grit sandpaper and gently scrubbed the tips then cleaned with isopropyl alcohol, fixed the issue completely. Now lightning fast performance.

5.0 out of 5 stars The best multi meter for the price in my opinion.
Reviewed in the United States on May 12, 2018
Verified Purchase
This is a fantastic meter by any standard; especially for the price. I sunk a lot of time and research into choosing this puppy. I purchased to replace a Fluke 289 I have had for many years (a meter that is still at least 7 times the price of this one). Over my years of usage with the Fluke I came to love it's accuracy and fluidity but loath what I consider the price gouging that goes on with the gold standard in multi meters. When my Fluke started giving issues I decided to dip my foot into the Chinese clone market figuring after 7 years or so of technology advancement somebody should be able to build a decent meter for under $60! I was not disappointed at all with this meter. The physical and electrical build quality is good. Structurally it is about 75% that of the Fluke which is way over engineered (the Fluke is designed for field abuse, day in day out). Electrically (safety wise for high voltage work) I'd say it's also 75% compared to my old Fluke (I'm talking about the contacts inside the case if you were to open [don't do this unless you know what you're doing], blow out separation on the main circuit board, etc). If you're going to be doing very high voltage work (above standard mains power) the Fluke 289 will withstand a "catastrophic failure" better than this meter, however I have used this meter with mains power (110/120v) quite comfortably. I even gave it a little trauma test on mains power (do not do this) due to a rather tricky high voltage frequency measurement. It squealed like a stuck pig (the warning tone) but it didn't even shut down or lock up. When you understand the level of power and energy inside your humble electrical socket you'll understand why this impressed me a whole lot and gave me confidence to do almost any DC work which is low voltage compared to mains power. I've been using this meter almost daily for several hours a day since I got it about a month ago and I have fallen in love with it. I've hit it with 1-2A current analysis at 12V without any issues. Also been current testing in the low mA range without any issues. I like the fact that the meter is paranoid about safety and will give warning tones with rapidly rising current in the sub 500mA range because low amperage ports are only fused to 1A. I think that additional audible alarm on fast rising current can save many a newbie from a blown fuse and even experienced users from carelessness.
I'm comparing this meter to a $500 meter and I can honestly say unless you're a field technician working for some sort of utility who will be dropping their meter, bumping it into stuff and subjecting it to much abuse there's no reason to be fleeced anymore by the big boy on the block. Also for the price of this meter you could afford to blow one up and buy another for the price of the lowest priced Fluke available (which is NOT the quality of the 289; which is a "professional" meter). I hope this review helps a person or two. I was really skittish about spitting out the "yellow lemonade" of the big brand for this relatively unknown but I hope the manufacturer keeps this up because they've got a winning combination on their hands with price point vs quality. The accuracy is as good as the Fluke, the speed to update is very slightly less and the leads are plastic not silicone. I've purposefully used the plastic leads instead of the Fluke silicone ones I have just to test the unit "as is" and while less convenient than the silicone leads I can live with them and I'll save my silicone leads for when I need them inside a vertical panel box full of wires and other tangle hazards rather than my lab workbench where I can comfortably route the cables out of the way. Hopefully this baby will keep serving me for a long while. If you do enough experimenting and research you'll subject your meter to electrical abuse eventually. Paying more than the cost of a good oscilloscope just for a multi meter in this day is just down right ridiculous unless you're in very specific lines of work. I'll update this review sometime in the future after more adventures in Mr. Ohm's playground. Hopefully I'll still be as pleased as I am today.

PS: I treat my equipment well. Any abuse my equipment suffers is in the line of duty due to the nature of my work. If you are new to meters take the time to study, learn and experiment safely at low voltages and currents before moving up. READ the MANUAL and follow DUTY CYCLE WARNINGS! If you want to "dive right in" buy a $10 meter and expect to blow it up :-) Electronics is a beautiful thing, but electricity is unforgiving. Also you can't buy a new life!

Decent chinese product by a rising brand. At this price range it is a very strong competitor.
Sturdy, decent build with nice features. 20000 count is attractive (it worked on me) but be aware that very few devices have the precision and the accuracy to back up that many digits on the readout. They usualy are "precision" desktop devices from major brands (e.g. HP, Agilent, etc.) and cost more than ten times the price of this little Uni-T. Look at the specifications and do the math. And given the unestablished nature of the brand, take the specs with a bit of salt, too. Also, keep in mind that the device is not calibrated formaly, and therefore you can only count of the QC of the manufacturer. All in all, look at the indicated value with a certain indulgence as you should anyway, for any device in this price range!
After these caveats, why 5 starts after all? Because the whole package - device plus price, placed in the context of the competition, is a good deal. At 45-50$, it's a decent build with nice features: autoscale that works ok, decent precision (specs are not bad! Do a bit of comparison with other manuf., weigh the brands and still this is a good choice), freq. and capacity measurements, mV and uA scales, relative measurements. Measurement speed (display update speed: ~3Hz I'd say) could be higher, but it works ok. The computer connection is DB9 serial port based, which you can hardly find on current desktops (let alone laptops). Didn't find a partiicular need for it so it doesn;t bother me, but if you plan on using it, think usb/serial adapter or know that you still have a serial port somewhere.
At 50$ you can hardly find better.

The meter is functionally top of the line, pricewise the unit is middle of the road. This meter is built very well, it’s not a Fluke but it’s not priced like a Fluke either. The product was packaged and shipped flawlessly; no excessive packaging, environmentally friendly and shipping was spot on with tracking telling me exactly where the product was. This was difficult considering the absolute shutdown of the transportation system during the winter storms. The product shipped with the UNI-T UT61E multimeter and test leads, an instruction booklet along with a micro-CD with software and a USB/serial cable, and a very interesting connector that plugs into the meter allowing easy measurements of electronic components. The meter has a good grip feeling, sturdy and secure, the decaling of the meter is good with easy to read labels and button functions. The range selection knob is well designed with easy to read settings and is somewhat recessed and out of the way. The LCD panel is of good reading size and displays both measurement readings and meter function settings. I have tested each of the meter functions and was pleased with the meter accuracy and ease of operation. You can read the product details to find the meters capabilities which are impressive. I am pleased with the product, pleased with the price, and am looking forward to a very useful tool in my electronics experimentation.
