Mix, match and compare!eg. An Aneng 870:https://www.aliexpress.com/item/33004463675.htmlPS: Aneng just launched a whole bunch ofnew meters.

content: Quote from: Fungus on October 29, 2020, 05:47:06 pmYeah, my thoughts exactly. If the UT161E turns out to be as good as it seems - safe, good bargraph (uni-t seems to be skimping on this lately with those "as-fast-as-the-counter" bars), inexpensive and accurate I can see myself buying one. Normally I don't deal with high voltage but If I can get a safe meter why not?Quote from: Fungus on October 29, 2020, 05:47:06 pmI've got an AN8009. Love it, I take it everywhere with me, it's an EDC meter. But when I'm home I reach for my ut61e every single time. Another one I was considering buying is the Owon B41T+.Ill look into the Aneng 870...

It also has an excellent bargraph; it is sad to see them skimping on that.Quote from: Fungus on October 29, 2020, 10:39:36 pmI agree. I have the RM219 (Aneng An870) and it is much better than the smaller ones.@the OP: sorry for the shameless plug but, if you are not familiar, I did some reviews of the UT61E and the RM102Pro on my Youtube channel. I still need to take heed of a few loose ends to finish the review of my RM219. The channel is athttp://videos.vbeletronico.com

It should default to the resistance scale. I'm waiting for the 11.11 to see if there will be additional discounts.Quote from: ResistorRob on October 30, 2020, 10:35:52 amI remember someone saying that the transmission protocol is very crude and because of that it is very hackable. When UNI-T updates their download section on the UT61E+ / UT161E if it is the same software it is possible that it is compatible with the current bluetooth adapter.Quote from: Fungus on October 29, 2020, 10:39:36 pmMaybe I'll get one later as a carry everywhere meter. It's only a little more expensive and it really seems good. I think I've been infected by the MAS-19 desease (Meter acquisition syndrome-19). No vaccines for me please

content: I missed this video but it is very revealing. Can you spot the slow bargraph update on the UT161D (1:50)? The E model is shown afterwards testing a 9v battery. The bargraph lags changing the scale. Doesn't happen on the original, I've just tested it. Damn...Guess I'll wait someone to review it before I buy. Uni-TISskimping on the bargraph function, or it is the video's bad editing.

In need of a decent general purpose meter and this looks like just the ticket. About once per year I need to do a remote measurement and if the module works it will be a nice bonus.Quote from: sot010174 on October 31, 2020, 12:38:09 pm- I know web programming (PHP, JavaScript) but don't know much about transmission protocols, but it's something I have been wanting to learn. This could be the perfect project to mess around with.- I agree this meter seems really good.- I also suffer from Meter acquisition syndrome, except for I tend to collect the weird and rare stuff, so getting something practical like this would be great. I do have 1 budget meter that is amazing, but it doesn't have Bluetooth, so if I can get that working on this meter then I should be able to handle the majority of stuff I work on.

Otherwise, it could be simply offloading of the same old crap in a different dressing.

content: Hello friends!Sanat Klaus brought me a present under the Christmas Tree! It's new UNI-T UT61E + Plus!It has a great design! This is the most beautiful tester I've ever seen!But there is a fly in the ointment in a cup of honey!Are you interested in the text review and comparison with Brymen BM869S(Plus Edition)?Accessoires Included:- 2 probes. They are tougher than the brymen.- Ugly Bag + 2 high voltage clips. It was a gift. Made of poor material and does not hold its shape. hFe adapter does not fit there. Brymen's bag more better!- USB computer cable with optical sensor- hFe adapter- Waste paper. Instruction and warranty card.From the pros, it measures quite quickly. At first glance, it is roughly comparable in speed to brymen. Warns with a signal and a flashing LED about high voltage!It fits very comfortably in hand! More convenient than brymen. Brymen is huge and not comfortable.Cons, no temperature sensor, it's in the D + model. Apparently it can be purchased separately and you can measure the temperature in the hFe mode. NCV very slow.The screen is not bad. But worse than brymen. It has good viewing angles when viewed from the side or bottom edge. Best viewing angles from the bottom edge of the view at an angle of 30-60 degrees. When viewed from a 90 degree angle, the image is not clear. The worst viewing angles are from the top edge, as soon as you slightly deviate from 90 degrees towards the top edge, the image immediately becomes completely unreadable. Apparently this is due to the cunning polarized coating, which is designed for more viewing from a natural angle.

content: Thanks comrade!I just wanted to show the measurements with both instruments so that people can appreciate the quality of the measurements. The main difference is CAT, Brymen has better security. UNI-T has slightly less accuracy. For the repair of equipment, this is an excellent device, it fits perfectly in the hand. I'm also interested in how it reacts to power supply ripples, and at what frequency the measurements will float.

It is certainly not useful for identifying the presence of live AC wiring behind walls. Perhaps the use case uni-t is supporting is where an electrician has direct access to a potentially live wire. In that case the electrician needs to know if that specific wire is live, not just whether there is live wiring in the vicinity.Or maybe the NCV on the ut61e+ is just garbage

Yes I'm a glutton for punishment.Soldered a breadboard jumper wire to the collector, then plugged that in to the collector hole on the hFE adapter. Connected 2 breadboard jumper wires to the base hole and emitter hole on the adapter, then used those 2 as hand held probes on the sot-89.

content: rernexy, I am not an electrician, but sometimes it becomes necessary to work with high voltage. For example, I recently did home renovations, and it was necessary to shift the wiring and add sockets. Also in the country, and in the garage.I bought a tester with the hFe function because I need to measure transistors periodically. Cheap Chinese LCR transistor testers lie, and show different values ​​every time you turn it on and on a different battery charge. By the way, they also measure LCR crookedly and the values ​​are far from real. Unfortunately, I have not been able to check the quality of these measurements in UT61e+.I have a Chinese AD584-M module with a voltage reference of 2.5v, 5v, 7.5v, 10v. Uni-t ut61e+ shows closer values ​​to those indicated on the calibration sheet created on the HP 3458A.Brymen bm869s has more discrepancy in readings. Probably these calibration data are fiction and made by some Chinese tester. I doubt uni-t ut61e+ has better accuracy. But I don't have better voltage reference at hand to check it.UPD. I found a way how to place the hFe adapter in to the bag. After I changed the probes and put the probes from uni-t ut61e+ on to Brymen bm869s, it began to show closer values and has better accuracy. Probably Brymen soft probes have higher internal resistance due to thinner conductors for better flexibility.

Odd that only one of the four PTCs have has a cover. Guessing it is similar to my UT181A which used two PTCs in series for each leg. That arrangement can certainly be made to work and it may handle some abuse. Then again, it be easily damaged like most UNI-T products I have looked at.Price on Ebay looks about $100 USD.

From 50mV to 60V it was never off by more than 4 counts !!I have a calibrated Resistor Box and from 1.0 ohm to 1.0M Ohm it was an order of magnitude better than the spec.( 0.5%+10)AC is arguable, since I have no calibrated source but it looks good too. It is spec'd to 10KHz but accurate to >100KHz. (-3dB @ 700K)Frequency is usable to ~70Mhz if you blast it with 300mVrms, and only 10Khz resolution. Sensitivity at 1Khz is ~100mVrms.Caps seemed to be in spec (3%), and agreed with the SDM3055. Still need to test the current and diode measurements.I will not use it for NCV, it really lacks sensitivity. The loud beep for 'turn me off' is a bit annoying, but can be turned off.I was able to get the USB working on Windows10, but not on Linux which is a big disappointment.

I would not necessarily have a problem using the plain UT61E on this scenario, but since I don't know your experience, the more conservative assumption is to keep the recommendation to a certified multimeter.The UT161E, however, gets dangerously close in price to the excellent Brymen BM857 and BM867 (tme.eu), both edging the UT161E in features while having the weight of an excellent and reliable brand. With a loss of counts but at the same price range you have the also excellent BM257.Good luck in your quest.

content: Quote from: WilldV on February 18, 2021, 10:53:23 pmThat depends on what you mean by "safety". There's two aspects to that, "user safety" and "meter robustness" how likely the meter is to die.User safety depends on user procedure as much as anything else. If you connect the meter up to the AC power in amps mode then a good meter will minimize the user excitement. The real trick is to not do that in the first place (or own a meter that doesn't even have an amps mode for those measurements).Meter robustness means how likely you are to have to go and buy another meter afterwards. Anything with big motors can easily damage a multimeter. Uni-T don't have a great record in this department.

How likely are you to poke at an arc-flash hazard with the leads in the current sockets? Will it ever be in the hands of the sort of person who tries to measure how many amps a mains socket has? Would the Uni-T be safer in those situations or should you only trust things with UL markings?(Would measuring mains amps with a glass fuse even be dangerous or would it simply blow with no problem? How much of the safety debate is FUD on a hobby workbench with Arduinos and 12V power supplies? Is basic education worth more than the safest meter in the world?)At least the Aneng's fuses are standard size and could be replaced with ceramic equivalents for 50 cents.

content: @Saskia, thank you for the photos. It looks much more put together than your typical Chinese meter. Obviously that, to be absolutely certain of its robustness, testing would have to be made.

content: I can check the feature list. It did come with test leads, a USB adapter and a component test adapter. I did not see a temp probe, though. Did not check official pricing. Found this one on the returns shelf of a distributor in a torn box which lead to a below 50€ price. Is it worth it ? I don't know. It will not be able to compete with my Fluke 179 or my MetraHit. But those are in different price ranges.

content: Quote from: Trader on October 31, 2021, 04:09:07 amThe burden voltage on the current ranges is exactly the same as that for the UT61E+.The UT161 is the same as the UT61E+ except for the improved input protection and having undergone a certification process. The plastics are the same, the main IC is the same, the features are the same, most of the PCB layout is identical, it probably comes from the same assembly lines, etc. And it's very slightly more expensive (the price difference is under 5€), imo that means it's better value.Quote from: rsjsouza on October 30, 2021, 10:19:10 pmjoeqsmith already tested the UT61E+ for "robustness". This is exactly the same meter except for a slightly different input protection.Quote from: Saskia on October 30, 2021, 07:19:16 pmThanks for the pics.

content: I'm going to buy one in aliexpres on November 11, since the unit is going to make a good reduction, since I only have the ut61C, you always have to have two or more meters. Maximum voltage with which I work 250V and currents that do not exceed 5 or 7 amperes, to measure more I use a homemade probe that measures the voltage drop through a resistance of 1oHms 50w.Yo voy a comprar uno en aliexpres el 11 de noviembre, ya que unit va a realizar una buena rebaja, ya que me quede solo con el ut61C, siempre hay que tener dos o mas medidores. Maximo voltaje con el que trabajo 250V y corrientes que no superan los 5 o 7 amper, para medir mas uso una sonda casera que mido la caida de tension a traves de una resistencia de 1oHms 50w.

content: Obtained UT161D (the certified version of UT61D+). What I noticed immediately after initial testing is how badly it behaves in continuity test mode. Yes, it latches fast enough but then it interrupts beeping momentary if you go on keeping the probes shorted. This is not the case with the more expensive UT61E+, but the D(+) version is probably quite slow at measuring resistance, which causes beep interruption until reading drops below 50 Om to engage it back, indicating a shorted circuit.This is quite annoying as it stops someone from reliably judging about the circuit condition.Uploaded short video to visualize the issue:https://youtu.be/0HC-WeQ5inA

That's a rebadged version of UT61E with better protection. The innards look very similar to the ones of UT61E reportedly sold on the EU market (German GS, as shown here:https://www.eevblog.com/forum/testgear/uni-t-ut61e-multimeter-teardown-photos/msg581051/#msg581051).Unlike UT61E, it comes with both RS232 and USB computer interface cables (and a CD with software).https://www.newark.com/tenma/72-10415/dmm-hh-10a-1kv-22000count/dp/94AC6580

content: Quote from: AlexTee on November 13, 2021, 04:00:16 amI know. The old UT61E was infamous for inconsistent input protection. Most versions sold on Aliexpress, Amazon and eBay had only partially populated boards (missing some components), smaller fuses and false CAT ratings. Other than that, they were fine meters - people liked them. Some complained that the IR/USB cable was optional (an IR/RS232 cable was included by default). Reputable dealers such as Newark sold better versions, with proper input protection, fuses and true CAT ratings. Unfortunately, you'd have to pay almost 3x the Aliexpress/Amazon price for that, which was hardly worth it for an UT61E.With UT61E being phased out, Newark is selling their remaining stock at almost 1/3 of the price. As one of the ways the new UT161E is better than its predecessor is, allegedly, better input protection I thought some people might be also interested in a properly equipped UT61E with an IR/USB cable for a fair price (I was).

I finally decided to bite the bullet and I bought it on sale.Now I see not only is the 161E better, but also cheaperCan someone explain me the difference since I don't understand the Russian video?Are the fuses the only difference or is there more?Should I sell the 61E+ since it's unused and get the 161E?

content: The fuses, Intertek certification and the box content; the 161E comes with bag and a smd/thermocouple adapter. No huge difference, but yeah, they do sell them cheaper, I bought mine for just $55 last year from AliExpress. One thing to note is that 61E+ PCB has been updated with new revisions unlike 161E, which probably won't see any updates since it is a certified device, meaning Uni-t should pay for inspecting every new revision, which probably won't happen. If you ask me, sell it and get a Brymen, period.

content: Quote from: AlexTee on March 24, 2022, 10:26:16 pmMine came with probes ofc, transistor tester adapter, smaller bag which is more convenient for transport and a UNI-T voltage detector. Not terrible but I wish I went for the 161. Keep in mind that I'm from Europe so the price automatically includes 25% VAT in top.My local electronics store has those exact fuses. Are they worth upgrading?Also, I get a dead battery notification although I've inserted new, freshly charged NiMH batteries. 950 mAh or so. Don't tell me it doesn't work on rechargablesDoesn't the 61D come with the thermocouple adapter?

content: I beg your pardon. Both 61E+ and 161E come with transistor testing adapter, not thermocouple adapter, obviously. It is the 161D, that comes with smd/thermocouple adapter, but the 61D+ comes without, you just plug the thermocouple directly into jacks.You can't directly replace the fuses of 61E+ with ones that come with 161E, they are of different sizes. You'll need to first replace the fuse holders. Not worth it if ask me.I never tried the nimh batteries, can't comment.

I was wondering if it's worth the trouble.Generally I'm happy with the meter. Much faster than the old one. The low battery notification and OL notification that I got when measuring a power outlet are the two things that annoyed me.I measure 240V AC and I get the buzzer and the OL reading. Is that a bug or am I doing something wrong?Thank you for your help!

I was thinking about the Uni-t 61E+, because of its good abilities. But after reading some posts, now I am not sure. The Fluke 15B or 17B can meet my needs. And I can afford them.What do you recommend?Are they really better? do they make a difference in work?

AN870) and I don't put the UT61E+ in the "safe" meter category.The ONLY reason I'd advise somebody to buy a UT61E is for the data loggingability. If you don't need that then there's no compelling reason to buy one.Quote from: Alibani on July 19, 2024, 09:46:50 amThey're certainly better built, safer, and more reliable.I'd prefer a Brymen for best value for money but if Brymen are difficult tobuy where you live then a Fluke 17B+ is a good choice.There's good tests of both meters here:Dave's thoughts on the UT61E+ are here:And Fluke 17B (nb. old video of the original 17B model, not the 'plus'):
