You can find pre-crimped wires that are compatible with all of the major known systems, but the ones I've shown are compatible with JST PH style 2.0mm pitch connectors.

Yes, I really wanna do those I just haven't found the time resources to get around to that. But thank you for reminding me, this is pushing me in the right direction! :-)

Noted!

Thank you!

Thanks! I would like a simple charging module for Na Ion cells too!

Typical characteristics of these cells : Nominal Voltage: 3.0V Operating voltage: 1.5~4.0V Real Capacity: 1300mAh Energy Density: 128.00Wh/Kg Cycle life: >2000 cycles Charging Temperature: -0℃~35℃ Discharging temperature: -40℃~60℃ Storage life: 15 years

Let it sink in for a minute. I would not doubt for a second that these metrics are purposefully vague and circumstantial.

Thanks! I will look into it!

Weird, the same happens to me! 🤔

Seems like every few weeks I have the same problem. Not necessarily the items on here, but I definitely see Aliexpress packages arrive afterwards. 😎

Thank you for your feedback! I'm gonna review several different AWG from UNI-T soon.

Nice! Thank you for sharing.

Thank you!

That's a very valid point for those that are going to comment and trash the model or mfr because of something like that :-)

I generally agree with that view and important to add is that UNI-T price their models lower than the competition.

It is. Precision custom metal film networks, TCR down to 1ppm, stability class 0.025%. The Max6225 datasheet contradicts itself - the 1.5ppm typ, 3ppm max applies to the DIP package whereas the AESA+ (SO package) is shown as max TC of 5ppm in the table on the first page. Who knows what the typical value is supposed to be? (Not that 'typical' means very much).

Thank you for sharing that. Again, another valid point for me saying a lot of high quality parts seen in this assembly.

What looks pretty bad exactly? Can you be more specific?

Please share more details, it's important to understand what looks pretty bad to you.

@@sebastian_harnisch Hello. Yes i can share few details. 1. Cooling of those heatsink is not needed. Instead of small heatsink they could put bigger one or use chassis as heatsink as it is done with other models or they could use specific low dropout regulator 2. Those crimps/input terminals looks skimpy at best plastic doesn't look like any good choice..yes it is cheap but that is about it.. ..i didn't see any good precision resistor there..yes there were few but for good equipment you need good low tempco resistor with good voltage source. 3. Voltage source is so so ..nothing special i would rather use heated voltage standard instead of just solution on chip but this is just my discussion. 4. RF shielding isn't good as i see it.. i didn't notice imput dedicated chassis filter(but i might be wrong on this one). ..and much more.

@@SylwerDragon I find it a bit difficult respond. I guess it depends on what you expect. You’re neither paying for Keysight nor are you getting Keysight. It’s not a reasonable approach to just say „you need this or that number of precision resistors. You have to characterize the unit and see whether it meets its specs. If it does this argument is pretty pointless. If it doesn’t then *that* is a problem. I agree that it would be nicer to have a voltage reference like the LM399, but then again, for an affordable 5 1/2 digits DMM the choice seems somewhat reasonable to me. I’m not 100% sure, but I think that most direct competitors (Siglent, Hantek etc.) have a very similar approach (MAX6325 or similar). If you know of an equally affordable new DMM with a better voltage reference, please let me know. I‘ll leave it at that. This is not to say that I‘m 100% impressed and would recommend to blindly buy cheap test equipment - and personally chose to go with two used 34401A. But I think it’s important to state facts and give explanations so that one can judge whether an argument is worth considering.

@@sebastian_harnisch I understand.. to your findings lets say. 34401A is what i bought twice myself including some improvements i made on it and such..but that is basic of quality/design i would start with 6.5Digit. Ofc i understand cheaper you go less options you will get..but again ...As company you don't care about cheap equipment you pay a bit more for good one ..but that will last for years to come.. as individual used equipment is way to go..but there are brands you don't want to go with and UNITy is one of them but ofc choice is yours as they say :) not because they make bad equipment but because they usually make cheaper equipment with less quality/design on mind and more to price.

Makes sense maybe from some weird manufacturing limitation because why wouldn't they be able to the same indent to the bottom metal plate?

Bench top multimeters are generally not the right choice for hobbyists who only use them occasionally and they don't need the precision or the accuracy of such an instrument. There are hand held meters that are more affordable for that type of usage.

I am not aware of any good oscilloscopes with low to no fan noise.

There shouldn't be any limitation, this gateway can communicate with all Lora devices.

This will be an interesting experiment, let's see if UNI-T fixes any of the problems discovered in this review. At that point, given the specs and the price the UNI-T is probably the best choice when compared to Hantek, Siglent which offer similar meters but higher priced. About the test clips, YES, I made these for that exact reason. Silicone cable + mesh sleeving and some heat shrink and you get something that's gonna work great!

and Siglent is clearly copied from the Agilent UI.

Siglent, Hantek, they all have similar layouts and menu setups for this type of instrument.

@@voltlog Yes let's see how they handle the issues. Honestly i wouldn't go for uni-t over the siglent if i can pay the extra diference, but yes very good for the price if weren't those issues.

Ok, I get that, trust is important :-) But if you could be sure that a new meter delivers high accuracy results, would you still go for the old one?

@@voltlog hmmm. 9 times out of 10, the older stuff is built better. Goes for a lot of tools. Go buy a new medal file, and then go buy one that is 50 years old at a garage sale.

Ive seen other videos reviewing these and they had the same problem with the upgrade but I think they had the continuity buzzer 👍

@@GeorgeGraves agreed, a Keithley 2000 or 34401a for ~same price (or less) would be my pick, but this is coming from someone who likes old test equipment. I’m curious what the reference is in this meter though, depending on what it could be worth it to someone who wants a graphical UI. With that said, old equipment usually comes with a nicely aged ovenized reference 😛

Hantek costs a lot more, $600-800. But yes has proper charts and recording.

Around here the UniT UT8805E cost 409,09€ + VAT, while the Hantek HDM3055 cost 453,72 + VAT.

Specs are very similar, cost is roughly 50 EUR higher for the Hantek at EU distributor eleshop.eu. The Hantek does have rear panel terminals which the UNI-T doesn't have but I'm curious why would you choose the Hantek?

@@voltlog 30ks/s vs 5ks/s, and has graphing and statistical plotting. Looks like they have a 6.5 digit model as well, so I thought the price was a lot higher ($700).

Indeed that higher sample rate could be useful in some cases and I believe you're right that it's graphing and plotting capability is a bit more advanced on the Hantek.

Thanks for watching!

Indeed the Siglent SDM3055 seems to have very similar specs and functionality yet UNI-T seem to price theirs 60 EUR lower at least with the EU distributor eleshop.eu so anyone evaluating these two would probably go for the UNI-T as I don't see any advantage to the Siglent.

​@@voltlog ​ Because you don't see *any* advantage, which is a bit surprising to me, here are some, without going into the specific functions of the meters - I own neither so I can't really comment on that part without doing a ton of research. 1. Since the Siglent's Bench DMM series is much longer on the market I would expect most of the more critical bugs to be fixed by now. 2. Also a somewhat more, but not completely subjective argument: For now I have a more confidence in Siglent than in the Uni-T bench DMMs, mainly for the following reasons: a) They have a longer history of building this type of equipment, b) the series of DMMs includes higher end 6.5 variants, from which the design of the lower end models *might* profit to a limited degree (I did not research it, so I can't say to which extent or if at all this is the case) c) From what I can see they generally have more experience building higher end equipment than Uni-T (scopes up to 4 GHz, 26.5 GHz spectrum analyzers etc.). That being said, it is an older design that might not represent today's capabilities that I mentioned before. Anyways, Uni-T has to build that trust first, e. g. by supplying firmware updates for the mentioned bugs in a timely manner. The build quality of the power supply you reviewed recently is promising though.

I'm curious how does the HP 3468A have a USB connection? Did you hack it for that?

On the other hand the UDP3305S PSU that I reviewed a couple of weeks ago is very quiet, much quieter than the multimeter.
