A man with one clock knows what time it is. A man with two clocks is never sure. A man with one meter knows what the voltage is. A man with two meters is never sure. 😁

@sdgelectronics 2 года назад

That's definitely the case here!

@mortenhattesen 2 года назад

But with three meters, you have a reasonable level of confidence if (at least) two of them read the same. Although you COULD be unlucky that the two meters have experienced identical drift, and it is the third meter that shows the good/best reading. Mind you, a good reference that has been aged for 10+ years seems to drift very little (as my 34401A and 3458A has shown)

Been using the 3055 for a month now. It is surprisingly good at a reasonable price point. I think these are well designed and built, which is quite far off from their previous products. I also got their new linear 4-channel power supply. It was very reasonable in price as well. Love their new direction with these new generation of products - 5.5 & 6.5 multimeters and the linear power supplies.

@laurentcadet6523 2 года назад

After some quick research on mouser, it seems that the "best fit" (as long as the package and the different in/out pins are concerned) is one of the MCP3562R or MCP3564R. 24bits up to 153ksps deltaSigma ADC with +/- 7ppmFSR of INL (at best) and max 2ppm/°C Gain Error tempco (at best).

@sdgelectronics 2 года назад

@IanScottJohnston 2 года назад

Certainly the 3065 looks to be a Keysight 34461A on a budget, half the price!......depending on which of the five 3065 models you buy! A shame about the voltage reference in the 3065 but if used in a stable, well controlled temp/humidity environment it probably won't be that bad (aging aside)......and I guess you can't really complain at that price. How repeatable/stable the 6.5 digits is would be fun to see.

@sdgelectronics 2 года назад

It's tempting to modify it, but I have no means to really check if I've made any appreciable difference.

@Nik930714 2 года назад

Ive had really bad experience with 2 equipments from Hantek in the past. One was a scope that would crash, not trigger properly and had around 10% error on the vertical scale (and each day it was somehow different). All of those issues were confirmed by me and 2 other engineers in the lab, just to make sure it was not an operator error. Also the UI was really unintuitive and slow the display would flicker when someone was making coffee When i wrote to customer support about those issues they answered "well the sample we have in our office does not have those problems" and they stopped answering. The other was a current probe. That one was working whenever it wanted to work. After i re-soldered all the components it became a bit more stable. I added some decoupling caps and it did work diecently after that. For the price it was still not worth it. If they have started to actually design and manufacture diecent stuff i may even consider them at some point. May be worth to keep an eye on them. Keep up the good work at bringing light to affordable equipment. I hope this one is as good as it looks at first glance.

@SidneyCritic 2 года назад

Not that I know what's going on - lol -, but what do you do with the code when the FPGA goes wrong. Other stuff you reprogram the bios or a ROM - usually with something off another unit -, but where does the code for the FPGA reside. From memory there is code to set the gates, another for the actual program, and they get loaded when it starts, so if it goes wrong does the whole unit end up in the bin as unrepairable.

@Ilyamiktotal Год назад

Hi. Will you tell me please what are its dimensions without bampers?

@renodasilva6464 Год назад

one thing that I don't like is the diode test, I have a t-Unit UT181A, which gives a short beep when the diode is ok, when it is in short it gives a continuous beep, and when I open it, it does not beep. the hantek only beeps when it is within the diode range, if it is shorted it does not beep. if you are looking at the circuit you will not know if the diode is shorted or open, just by the beep, you have to keep looking at the screen.

@antibrevity 2 года назад

I suggest wiping the stock probes with IPA before doing your first continuity test as they always seem to have a layer of something on them. Once wiped, they generally perform just as well as gold-plated probes. If fast response is important for a particular task, it may also be worth doing the IPA wipe before future use as well, but I wouldn't bother doing this every time.

@RK-kn1ud Год назад

I've seen videos on the internet that basically show what you explain, and there may be some truth to that. However, I've literally used the most disgusting and insufficient wiring as makeshift multimeter probes with my Fluke 87V and have never experienced any issues checking continuity down a chip that required a microscope to view and not have never had to slow down because my equipment couldn't keep up with me. We're talking probes covered in lanolin, cosmoline, bearing grease, engine oil, transmission fluid, dielectric grease, snow, ice, DOT 3/4. You name it, I've probably inserted a probe into it to check continuity. I'd be very interested to understand why my 87V doesn't care about anything yet the XXX3055 I just ordered is so selectively inept.

@HannesMrg 2 года назад

Thanks for the review. Are there plans to take a look at other "cheap" equipment? Hantek for example also have cheap scopes. I have the 6022be which is a super cheap (under 50 bucks) usb oscilloscope which does an awesome job for the price. Good (expensive) tools are awesome, but the cheap ones are quite fun and often not even that bad for hobby use.

@HwAoRrDk 2 года назад

Interesting that they chose to use a SATA cable for the connection to the serial interface board. I wonder why? Is the RS232 on a different pair of pins to the RS485? In that case, perhaps a SATA cable happened to be a convenient off-the-shelf shielded dual pair cable.

@sdgelectronics 2 года назад

I'm guessing it's purely convenience.

@jaro6985 2 года назад

It looks like they use the same connection style for the GPIB port, which has way more signals, so for the RS232 it ends up overkill. They might also use it for RJ45 but I couldn't see anything on the silkscreen.

@Duglum666 2 года назад

Thanks so much, i've been waiting for this video. Would you, or anyone else, say that the device is worth buying for what it is? And since the 3065 is "only" about a 100 bucks more compared to the 3055, maybe it would be a good idea to go straight for that one as it seems to have some better components? I'll never need the additional digit, even 5.5 is a bit overkill for my needs.. but this seems to be nice, fancy-ish and affordable? The only downside for the 6.5 digit one is that calibration costs are much higher for 6.5 compared to 5.5 meters.. if it's ever needed in years and years..

@sdgelectronics 2 года назад

Personally I think it's well worth buying if it's the limit of your budget and you don't want a second hand meter. So far I've not found anything to complain about, but the longer term reliability and drift is still obviously unknown. I would like a new Keysight unit, but they've gone up in price by £700 since I was originally about to buy!

@shlomsi2000 2 года назад

Thank you so much for a helpful review. I really think the prob continuity test a-la Dave Jones is not a real world test, as we rarely use the probs in such a way. A much better (IMHO) method would be to test them on a PCB trace with the sharp part of the tip, it would eliminate some of the oxidation errors.

@sdgelectronics 2 года назад

Good point. A better test would be a PCB hooked up so you can wipe the probes along the pins of an IC to test the speed.

@hqiu6828 2 года назад

Having read some comments, saying it is copy or rip-off, which is quite ridiculous! The voltage references are different, this one max6325, the keysight one LM399, so different design even though similar structure. BTW, Hantek is a great company with thousands of electronic engineers.

@panbekon1470 2 года назад

For top-end equipment, you can come up with the service manuals, schematics, etc. That's part of what you pay for. My guess is that, if Hantek is removing the silkscreen off of the chips, they certainly are not going to allow the service manual to be obtainable. Do you know the status of the availability of the documentation?

Nice meter, I’d still chose a 34401A if even slightly more expensive because this things just never die, but if I wanted a UI/USB connectivity this is very valid.

What? Superstar RU-vid influencer Mike Anderson is not in this? Opportunity missed.

I have a cal cert from Keysight signed by Tina Chen, Quality Manager. Same signature. What a joke.

Ripping off other companies designs guarantees I wont buy it. Why trust a company that cheats instead of putting the R&D into developing their OWN innovative products

They should change the "Design in China" to "Copied in China" blatant rip off of Keysight. Saying that I was tempted and the first thing I would have done is replace whatever crappy electrolytics they use for Nichicons but then I saw chip number scrubbing and that finished my interest, I refuse to support manufacturers who practice this. What are they scared someone will copy their copy of Keysight 🤣🤣🤣

Looks to me siglent is a step up. Won’t be buying one of these, think I’ll just go for the Agilent. Cheap piece of crap.

Unbelievable how Hantek copied the Keysight UI design! Just nothing they designed new! Siglent is doing the same. I think this is IP thieft. Look how Keithley develops their own UI design - completely unique one!
