content: Member "square circuit" posted on this forum back in July 8th 2019 that this meter was on the horizon. I have been checking every 2 or 3 months since then to see if this meter had dropped yet. Finally my wait is over! (I know where I'm spending my stimulus check, lol)The 5.5 digit starts at $400 and the 6.5 digit version starts at $570.They shied away from the total rip off of the look Keysight, and made it black so now it's only a 85% rip off of the design. If I had a black oscilloscope I might welcome that so it matched, but I'm planning on buying a Siglent so would have preferred the original color they planned to go with.Probably one of the cheapest options to get a histogram multimeter.Hope this helps someone who can't afford the A brands and wants something better than the really low end Chinese junk. Specs seem impressive for the price. Unlike the Tonghui TH1953 I bet the histogram feature actually works. I'm hoping someone does a review on this meter soon!

content: Quote from: coromonadalix on December 29, 2020, 03:23:49 pmThat publicity is from an independent seller and not from Hantek.I kind of like the black trend, except I like everything to match so I hate that it will cause my bench to be a mix of colors.I agree the light blue display looks terrible against the black. I frequently modify my meters to have a different color background so I will probably do the same for this one.For anyone confused about the models I think the "B" version adds LAN, and the "H" version adds LAN and GPIB

content: Quote from: ResistorRob on December 29, 2020, 02:53:18 pmThanks for the link Bob! Sadly they don't have a manual available yet to download (or I couldn't find one). The unit does look impressive but they also need to update the spec sheet. For example they list thermocouples for temperature sensing in one place but then offer no info on that ability. It would also be very interesting to know what that arbitrary sensor function is, I'm assuming you can apply a simple slope function to the input.As for appearance - looks good to me. Of course that means nothing if the meter has objectionable quirks, so yeah hopefully that testing will be done soon. Maybe this turns out good enough that Dave can offer the meter as a high end option for the EEVBLOG. Of course that would mean blue rubber 😅.By the way the one thing that constantly pisses me off about these bench meters is the low CAT ratings they all have!!!!! I regularly pull meters off the shelf to calibrate or diagnose issues on tools in the plant. Generally the controls stuff is well separated from the high voltage stuff but weird things have happened in industry. Often I go this route not so much for the extraordinary accuracy of a meter like this, but rather for the convenience over a handheld meter or functionality not had in a handheld.

content: It looks really cool and, if I had enough disposable income, I would definitely pull the trigger on one just to probe its performance. However, I would be very wary trusting it with accurate measurements without a clear calibration manual and heaps of tests. Hantek is famous for cutting corners, lacking in software and support in the long run.At this level it becomes a lot about trust itself, otherwise I would simply take one of the other high count meters such as the 60k count U1282A or the 50k/500k count Brymens.

content: Further evidence that caution is needed dealing with Hantek. Imagine a US based company, playing on the international stage, that debuts a new model without manuals in a number of languages. Beyond that you can't even find the Chinese manuals on their web site. It just looks like the device was put up for sale before it was ready.Personally I'm not too sure I would worry about this meter in the next 6 months. If Hantek can't demonstrate better support in that time, the meters "cheap" price is looking to be a bit expensive.DaveQuote from: Tjuurko on December 30, 2020, 03:29:20 pm

content: Everything indicates that the part with the display / buttons in both versions will be the same. (There is a DM55 / 65 marking on the PCB). The most important thing is how they made the analog part - input dividers, reference voltage and the issue of protection.In my opinion, for the 5.5 digit version, the input divider should not be composed of 1M / 1206 resistors. As it was written, the input part of the HDM3055B is much cheaper than the Rigol / Siglent version. I am very curious what it looks like in the 6.5 digit version.

Unfortunately the past year of my life has been a nightmare, and almost became homeless so couldn't afford a new meter. haha. Maybe by some miracle they will fix the supply chain crisis and prices will go back down by the time I have some discretionary spending again! Keithley is my dream meter, but until then I would love this one. I'm just a hobbyist and I'm thankful for whatever I have even if someone else thinks it's Chinese junk. I actually love my current desktop meter, but this would be an amazing step up with the histogram and other more advanced features.I agree with you at $750 it's not the bargain it once was. I'm also looking forward to a review, since I have been insanely interested in this meter for a long time.

content: While I am happy to use B-brand oscilloscopes, generators and power supplies, I honestly can't understand the appeal of questionable-quality precision DMMs. Unlike other equipment, a DMM is supposed to be a black box that magically gives the right answer no matter what input you throw at it and it is often difficult to verify its operation. Even A brands often have subtle problems. There is a robust supply of used 5-6-7 digit DMMs that cost a fraction of even the cheapest new ones. And they are already well-aged, as opposed to fast-aged.

content: Unfortunately, I could not find even ONE example of these "used 5-6-7 digit DMMs that costs a fraction of even the cheapest new ones" here in Brazil. Yes, I have found some examples of good, but VERY old equipments (HP 34401A, Keithley 2000 etc), but none of them was cheap (they cost even more than what I have paid for my equipment). Besides that, I will have no warranty and they don't offer new features like Trend chart, Histogram etc.I have just received my equipment - it arrived yesterday. Well, I have made some tests, and as I can see by now, it's working very well, with precise and accuracy measures (I have compared them with a Agilent 3458A - 8 1/2 digits measures). All of that with a new and beautiful interface, and 3 years of warranty.I understand and respect your opinion, but I don't think I have made a bad acquisition. A think one of these "peaces of crap" would be a good option if you don't have enough money to buy a Keysight, or Keithley fantastic new equipments.

content: Indeed. Many countries around the world, including Brasil, have a very limited and overpriced used market - customs does not help with that, raising a "cheap" foreign import to a level that dillutes its advantages. People tend to forget that US is a planet on its own with regards to test gear.I am glad you are verifying it against a 3458 powerhouse - who knows? Depending on how the meter goes, you might be their best advertising.

I would must be very satisfied, but ... I'm having problems in my tests with software to connect HDM3065 to my computer/network.Ok, when I have decided to buy the HDM3065, I was expecting this kind of problems. Chineses companies aren't typically good with software, I know.Well, I'm still trying to use their software, and I have asked for help from Hantek. I will continue trying a few days more. In parallel, I'm looking for open software solutions, like this one: (which I have found here in this forum, and looks very nice)https://lygte-info.dk/project/TestControllerIntro%20UK.htmlI'll let you know of my progress ... or deception

content: The nice GUI on newer units is appealing, the histogram and plots too. But this is something that can mostly be taken out of the equation. There are free sw available for working with all these older A-brand DMM's, including some excellent sw shared by members of this forum to communicate with lots of older instruments. I use these with my meters and this gives all the "advanced functionality" I need. A DMM is supposed to be a tool you can trust, not only when its new, but many years forward. Even cheap Aneng meters are spot on for a fraction of the price when new, but I wouldn't trust them for anything to do with accuracy. Same with my Uni-T units.I've purchased older 34401A and K2000, both are many years old (the 34401A is an HP branded unit, that's how old it is). Both are still showing results in good agreement with each other as well as newer meters (34461A) I've compared against when I've had access to them. For what its worth, I've payed ~300$ for each for these locally (not in the US). The original owner of the HP was a big company that kept all tools calibrated, which increased my level of trust in its readings.I wouldn't say getting a Hantek unit is a bad decision, especially if there are no options for a trusted brand with many years of proven record. However, I would be much more suspicious of it than I would of a new meter from a trusted brand, and more suspicious than I would with an older well aged trusted meter that was calibrated for the first few years of operation at least. If you have the occasional access to other meters you trust for a direct comparison this can help build the trust over time, which is very useful. If you (Marco) will have the ability to compare it as time goes by, I think this can be of significant value to other forum members who are considering this meter.I actually do a "sanity check" for my meters from time to time (maybe once a year or so). Have a look at the attached picture below as an example. This was a measurement I took of a few weeks ago during my ~yearly "sanity check" of comparing most of my DMM's (and in this case the electronic load too), just to see if anything is out of expected bounds, or drifted significantly compared to the other meters.They are all in good agreement, despite non of them being new. Actually the one farthest out from the mean of the batch is also the newest meter here, the UT61E. Its 9 years old IIRC, and it was spot on when it was new. Now, it has drifted somewhat (actually it drifted mostly in the first 1-2 years and then more or less settled).

It wasn't easy to configure, as there are no information at manual. The Hantek support team helped, but I had to discover some information by myself.I have installed the Hantek software. It's a type of "remote control" of the equipment. It shows a copy of the front panel, and you can access most of the function buttons, but not all of them.I have also tested SCPI commands. That's the feature I wanted to use with the ethernet connection. It works fine, even using just a telnet connection with the equipment.

content: My first problem is that I have a Mac. So, I needed to install a Windows 10 Virtual Machine, and installed the software which I have downloaded from Hantek web page.The first software you have to install and configure is "Keysight Connection Expert". It's included on the software pack from Hantek. Using the USB connection, it is easy to use. You can see the instrument immediately after running the software. After that, you can send commands SCPI commands, start IO monitor and, after that, you can run Hantek HDM3000 app, which is a "remote control" of the instrument, where you can press virtual buttons, and see the readings at your computer.For LAN connection, first you have to connect your multimeter at the same network where is your computer, and configure Network Options at Utility / IO Menu. Insert a compatible static IP address, or use DHCP. Then, after you get the IP Address at instrument, you go to Keysight Connection Expert at your computer, then "Manual Configuration", and set the same IP Address. At "Set Protocol" section, select "Socket". You must use the default port 5025, and press "Accept". After some seconds, you should see the Instrument as you have connected using USB cable.I look forward you get it running, but if you need, just call me here, and I can try to help more.

content: I had to use a Windows VM for Keysight Connection Expert even though I was already on Windows: they had some kind of shell extension or kernel extension or something that scanned for license files every 10 seconds and would stall the computer for about half a second every time it did this. By "stall" I don't mean "a background process took up a bit more CPU" or "ongoing I/O hiccuped," I mean the cursor actually froze like we were back in the bad old days of cooperative multitasking where lag in a single process would stall out the entire OS and everything. It was bad. It wasn't just my computer either -- it happened on lab computers at work, too, but people just tolerated the hiccups. This lasted for over a year, IIRC.Since then I have switched from USB to Ethernet for all my instruments (Ethernet->GPIB when necessary). I don't need to use *any* proprietary drivers -- I can install everything I need from pip in python. No OS-level hiccups, No GB-size downloads, no proprietary blobs, no dragging around a VM. It's great!

content: Likely sunk costs of development and price of components. Took them quite a while to bring it to market and seems to have suffered delays. It does have specs on paper that seem to meet the price, but I get their feeling they're not going to sell very many without a quality reputation to back it up.

They lack income taxes and IVA, that would add on top of that some 25...30% or soIf the 6.5 digit Hantek don't have an attractive price compared to the Siglent 6.5 SDM3065, I don't see how would Hantek expect to sell that meter in Europe with prices well over the Siglent, and about the same of a Keithley or Keysight.

content: You can see the difference in the TRMS converter, there is a voltage divider as a module on ceramics (finally!). Unfortunately, the reference voltage does not look any better ... Temperature sensor close to the reference probably to compensate for the drift. Basically the same principle of measuring and converting.On my behalf, thank you for the photos - I was very curious what they changed in the 6.5-digit version

content: To a large part it looks like expected. The diodes and 2x8 SOT23 parts next to them are the protection for the ohms (and cap measurement) source. Looks quite a lot like the Sigilent SDM3055 in this respect. I don't expect extra memory there - more liks OPs in the SO8 chips.The 3055 likely still uses a RMS chip, just a cheaper model, that may only need one filter cap.The SMD resistors replacing the ceramic chip look quite small - so one may have to be a little careful with high voltage and the CAT rating.It is also odd to see only 1 string of the larger SMD resistors typical for protection. I somewhat miss 2 more of those for the protection of the Ohms sense inputs. Unless there is protection on the bottom, I would be careful with the sense inputs.For the looks I would consider the SDM3055E (SDM3045 with different firmware) the closest competition to the HDM3055.

content: I just purchased the HDM3055. I infrequently do electronic projects and wanted something to have on my desk instead of my Fluke 179 (the only other DMM that I have really used). I'm a noob. I have no previous experience of a desktop DMM, so I have nothing to compare to. Some first impressions, just on usability, not precision etc., after a day of use:- It's completely silent. The fan has never started, except on boot when it spins up (so I know the fan is functional). I value this very much and was one reason I bought this particular DMM, since I had understood that it is silent. Now I can leave it on without bothering me.Some annoying things though:- You can save preferences and settings, but there is no way I am able to get the button click beeps off after boot. My "man cave" is next to the bedroom, and I don't want it to start beeping when I turn it on late at night while my wife is at sleep. It's a few clicks to get to the menu setting to turn the beeps off, so some beeps are unavoidable AFAIK. If someone knows how to save this setting, please tell me. Other settings are restored though. Feels like a bug.- The Probe Hold feature would have been useful, but it does not work for my uses in practice. In this mode it is supposed to display the last 8 reading in a table. For example, I wanted to use it when matching resistors for audio projects (especially if you don't have 0.1% resistors at hand). However, it does not record a new reading if the new value is too close to the previous one. For example, measure one resistor at 99.96kΩ. The value is added to the list, good. Let go of the resistor. The infinite value is not recorded, good. Measure the next resistor, 99.98kΩ. The value is not recorded, since it is too close to the previous value. Useless for me. At least add a manual trigger option which works elsewhere, but not in Probe Hold. (When measuring voltages, it does not record the intermediate close-to-zero voltages, which is good, though). Also, the resolution is reduced, and there is no way you can effect this. It would be nice if you could configure the sensitivity for recording new values and the resolution.- When saving a measurement series to a file, the values are stored in reverse order, i.e. last measurement will be first in the list. Is this normal? So if you were to plot a graph, you'd have to reverse the list first. Why? (I just tested this quickly, so I may be wrong.)- You can set the date and time on the device. I would have expected it to record the timestamp of the measurements in the file, but it doesn't. Why not? If you want to draw a chart you can't know when the measurement was done. Sure you can set the interval between readings, but that I'd expect that to drift as each reading will not be triggered exactly on that interval, right? I haven't tested though. But still, why not put a timestamp on the readings. What's the clock used for? Just saving the timestamp to the file modification date?- Clearing the list of samples to be saved is in a completely different menu than where the samples are saved. There is a direct "Acquire" button that goes to saving samples (Save Readings), but if you want to clear the list you have to press Shift, Math, Statistics, Clear Readings (four button presses). The Acquire screen has an empty slot for the context sensitive buttons. Why not put Clear Readings there (as well)? (I tried to insert the attached screenshot here inline, but failed.) Then you go back to Acquire Save, then back to Shift, Math... Small thing maybe, but a PITA, especially since it could have been done better at the same cost without compromising on some other feature. Edit: There is no "shift function" for the Acquire button. They could even have dedicated that to "Clear Readings".(Save displays "Down writing to file.", should probably be "Done writing to file.").The display is good/ok. The colors get inverted if you look from above, starting at about a 45 degree angle. I haven't looked from underneath, but I suspect it is the same. From the sides it looks good all the way to 180 degrees. I have some minor backlight issue in the lower left corner. It's mostly visible when you boot it when the screen is black, but you can slightly see it in normal use as a brighter spot. It's not so bad that I would return it in hope of getting a better one, but a little distracting when you start staring at it. I guess most people wouldn't notice it, but I'm a little sensitive to things like this. ;-)There are no firmware updates available.There's no manual for the SCPI commands, but I tested a few commands from a Keysight manual, and the ones I tested works. I got the VISA interface working on Linux. I would have hoped to get a simple USB serial interface, but that did not work out of the box, and I don't know how to configure it. If anyone knows, please share.Despite my rant, I'm happy with my purchase, but then again, I have nothing to compare to. Anyway, it's so much more fun to use than a handheld DMM.

content: Storing the samples in reverse order is strange and more like a bug.A reduced resolution in the file / list is also odd. It is common to have more resultion in the file / PC interface than on the display, but not the opposite.Not having a time stamp in the file is a bit a thing of the past, from times when memory was expensive. It can still get shorter files and often the fixed data rate is good enough, or that data a logged directly to a PC. A time stamp would still be nice, sepcially if auto ranging is active and thus possibly not a constant data rate.For the resistor matching one could use a save to file as a work around, or have an extra dummy resistor for in between.A not so polished user interface is not so uncommon with cheap meters. It may take some time using the meter to really learn the features - at least those you need. After finding out most of the functions by try an error, it may still make sense to have a read through the manual.The real time clock may indeed only be good for the file date - still quite useful to have valid date and not just fictive one.

content: Thanks for your comments!Quote from: Kleinstein on October 13, 2022, 07:57:08 pmI'll verify that this is actually the case. I may be wrong as I only did a quick test.Edit: Now I'm positive they are in reversed order. I manually triggered measuring four resistors: 100Ω, 47Ω, 100kΩ, 100kΩ, in that order, and the order is reversed in the file.Quote from: Kleinstein on October 13, 2022, 07:57:08 pmThe file has increased resolution. The reduced resolution is in the Probe Hold where 8 readings are displayed as a list on the display.Quote from: Kleinstein on October 13, 2022, 07:57:08 pmOk good to know. Maybe they'll add it in a firmware update.Yes, I'll just log to the computer, but sometimes it is convenient not to have to connect it to a computer or start the computer.Quote from: Kleinstein on October 13, 2022, 07:57:08 pmYes, that could be a good workaround, but then I will only have 4 real readings on the display. Saving to file will work, and may be better anyway as I can get more than 8 readings and with more precision. The automatic hands off triggering of Probe Hold would be nice though, if it worked. If I had implemented it I would reset the trigger whenever it goes to infinite resistance in between the readings. I'm thinking of attaching a foot switch to the external trigger to get hands of triggering.Quote from: Kleinstein on October 13, 2022, 07:57:08 pmRight, yes, I did not expect wonders of one of the cheapest desktop DMMs I could find with "advanced" features. I read the manual even before I purchased it, and again after getting it :-)Quote from: Kleinstein on October 13, 2022, 07:57:08 pmYes, I just noticed when I tried to add the screenshot in my previous post that it adds the timestamp to the screenshot as well (not only the file timestamp, but in the actual picture).

content: Quote from: Otso on October 13, 2022, 07:23:21 pmI just tested measuring voltages with Probe Hold, and it works exceptionally well. The problem I mentioned seems to be when measuring resistance. I haven't tried anything else than voltage and resistance so far.QuoteThere's actually a shorter way than four button presses. When you enable the statistics display, then there is a Clear Readings option in the main screen of what your measuring. So for example, if you are measuring DC, then just press DC -> Clear Readings (two presses), and then back to Acquire -> Save. This is a lot better than the four button menu diving. Clear Readings is normally only shown when you have statistics shown on the screen as well, but there's something I think is a bug (in a good way this time) that makes it shown even without statistics. I discovered this by mistake. You have to press the menu buttons in a very specific way. (Can't bother to write how now). I can't see why they should ever disable the Clear Readings option in the main screen, since the menu slot is empty otherwise.The HSM3055 is getting better now that I'm familiar with it's quirks. Hopefully the UI/usability gets better with a future firmware update. I wonder if they accept and process user feedback.

content: Quote from: rsjsouza on October 16, 2022, 10:20:33 pmOk, here it comes.Short version:Select either the Trend Chart or Histogram display.Press Shift -> Maths -> Statistics -> HideThat's it! After this Clear Readings is shown on all display types (Number, Bar Meter, Trend Chart and Histogram) without statistics enabled.Long story:The HSM30x5 has four main display types: Number, Bar Meter, Trend Chart and Histogram. Number and Bar Meter do not normally show Clear Readings unless statistics are displayed. Bar Meter and Trend Chart always display Clear Readings, which is natural since that will also clear the trend chart and histogram. If you have the Number display and go to statistics and disable the statistics info, then also Clear Readings will disappear from the Number display. However if you first go to Chart/Histogram and then disable the statistics the Clear Readings will stay on Number/Bar Meter.The software developer probably intentionally removed Clear Readings from Number/Bar Meter when no statistics are displayed, because he/she thought that it is useless since it then won't have any effect on the currently displayed screen. This is correct, but it is still useful for clearing the buffer that will be saved to your file. I assume that it is a bug that it stays if you go via the Trend Chart/Histogram. Hopefully they won't fix this. ;-) The optimal solution, IMO, would be to always leave Clear Readings visible on all four display types.

(+Utility -> I/O Config -> SCPI)Regarding the user interface, I think Hantek, let's say, took an inspiration on the 34461A. I was watchingand everything looks identical, except for some more advanced options that are missing on the Hantek's meter, everything else looks the same.Looking at some pictures, even the layout of the components on the PCB are very similar on both meters.

content: Without a LAN connection the Hantek HDM3065 is listed for €847 at Eleshop and puts it pricewise about on par with Siglents SDM3065. But the Siglent has a better Voltage Reference and very important in my opinion better support. From the other Chinese manufacturer Rigols' DM3068 is a competitor too if you can get past its display. It is listed for about €820 with LAN and GPIB connections.... But I am personally also not very convinced about Rigols support and their drive to improve their products.

Hantek on the other hand.. I have issues with the 1833C LCR, and response from the company has been zilch. I won't be a repeat customer with Hantek.-Mark KC3PKK-

I just get an error 28 - It enumerates as VID_049F PID_605E which is a Compaq device if the VID is to be believed?RS232 seems to work fine, and it spoofs a 34461A if you change the SCPI protocol.(edit: actually you can use Zadig to install the WinUSB and it appears in Keysight Connection Expert)

content: Hi,I've just received a HDM3065. Quite pleased with it so far, except... I've noticed a bit of a problem.Since I temporarily have an Agilent 34461A on my bench, I decided to measure the same voltage source (~29V) at the same time and see how the two tracked. Pretty good until ~36 minutes into the test the HDM suddenly showed a measurement of ~53V. And then every 36 minutes thereafter, the same thing. Roughly 60V, give or take, rogue reading. Makes a bit of a mockery of the stats! The spikes are very definitely not real, as shown by the Agilent and also tested with a 'scope.Attached are two screenshots showing the issue. Note the spike to the right of the Hantek graph.Same thing on current measurement, spikes every ~36 minutes except -ve going this time showing as '-ve overload', and 2W resistance - once again higher readings than is the truth.This smells of software to me - but I can't seem to find any updated firmware on Hantek's website. I see there is a thread on SW for this meter but haven't had time to digest it and my skim of it filled me with dread...The software version is 2.0.0.6(2394081348), firmware is 04.01.07.04.23-02.05-21.Has anyone else noticed this issue? Or do I have a unit with a pretty whacky fault?I've emailed support@hantek.com but received no reply yet. This, I understand, is to be expected.Such a shame because the hardware seems pretty nice.Cheers,Jez.

content: I can confirm that it's software related. I manage to reproduce and observe the same behavior.Hantek sent me a firmware update but apparently it did not solve this issue yet. I will try to run more tests later to confirm.

content: Quote from: ali_asadzadeh on April 10, 2024, 03:08:54 pmI've never had problems getting a response from them by e-mail, I really don't now what happens. I now have direct contact with one of their representatives by Skype so it's much faster. I am not sure if I could share that, but I will ask.For technical support, I would recommend that you first try to contact directly the seller from whom you bought the equipment, they should have easier access to Hantek's support, and contrary to what appears, they are very responsive and helpful.I've also shared sometimes links from posts of this forum with them to see if they could help, but apparently, the moderator blocked their IP so they can't read the messages...Quote from: jezgb on April 10, 2024, 03:29:57 pmYes they are, I reported it to them and they sent me the new firmware to test. I'll run more tests later and report back to them and see what else they can do.

content: Just got the new firmware for the HDM3065(B). It looks like Hantek have fixed the issue that caused a spike reading at ~36min of logging.I've also attached the FW for the HDM3055 if anyone need it, but I don't have how to test that.After applying the update the multimeter will reboot, but you'll have to turn it off and on again for the new firmware to be loaded.

content: Quote from: Sairus on June 01, 2024, 09:36:55 amYes, I did add the missing parts to my HDM3065 and it can connect to a LAN without problems.You will just need to solder the LAN connector, a 1:1 LAN transformer, some 0603 resistors and 0805 capacitors. That's all, no other change in FW or HW is required. I have attached pictures with the components values for reference.The process is straight forward, but you will need to completely remove the main board to solder the resistors and capacitor on the bottom. Just unscrew the top cover and the front panel for that.

content: I recently bought an hdm3065b, I used its usb interface, but it doesn't allow me to use the multimeter's physical buttons, in addition to the interface being slow, I wanted to know if there is a way to just transmit the image of the multimeter's screen to the PC for monitoring and maybe put In obs studio, I tried connecting via LXI through the browser but when entering the IP only some text information appears.

content: Over promise? Hantek has a consistent record of really attractive hardware and specs, but their software developers seem to let their reputation slip, holding back and delay potentially successful products. The HDM3065 was so delayed for nearly a year before it was widely available.

The problem turned out to be that it requires a 2GB flash drive — it could see my 8GB one, but it wouldn’t update from it. And nowadays, it’s not so easy to find a 2GB flash drive )).I updated the device, everything is working perfectly. Thank you for your help
