content: I created this thread so that there was something specifically dedicated to "improving" the SDM3045X DMM.For those of you that don't already know, the SDM3045X 4.5 digit hardware is identical to the Chinese version SDM3055X-E DMM. With a fairly simple firmware modification, you can improve your DMM to 5.5 digits.I've been enjoying my 3055X-E for 4 months without any issues.To make the improvement, check out this post:Quote from: tv84 on December 31, 2021, 07:36:15 pmhttps://www.eevblog.com/forum/testgear/siglent-sdm3045x-enough-is-enough/msg3909188/#msg3909188- more details are in that thread if needed, I think they also covered "unimproving" the device.After modifying that specific version of the firmware, you can update to any unmodified SDM3055X-E firmware.Language default will probably be in Chinese. To change it:Click the Utility button, then System Config should be in English (2nd from right soft button if it isn't),then Language should also be in English (1st soft button on left if it isn't).The first language option should be English (but written in Chinese).

content: I tried to update my SDM3045X with a patched SDM3055X-E_2.01.01.12.ADS file, but it failed with "Update Fail" message.I thought maybe the file is somehow corrupted and tried to update with a SDM3045X_5.01.01.07R1.ADS file which would downgrade the current sw, but that fails too.The current sw version of my SDM3045X is 5.02.01.09R2, which is a bit strange, because the latest version available on Siglent's website for SDM3045X is 5.01.01.09R2.I tried with three different USB sticks (all FAT32 formatted) and all failed. Am I missing something, or why the firmware update fails?

content: Not suggesting it's your problem, but Siglent gear is known to be quite finicky about USB flash drives. I've sometimes had to try several different ones to get one to be recognized for firmware updates, and have read countless reports of same from other users. Once I found one that worked, I labeled it for Siglent use. I keep all my flash drives in a zippered case that's bulging at the seams with probably 2 dozen varieties, so I could never remember which ones worked well and which didn't until I labeled one.

content: Quote from: jas on September 21, 2023, 05:37:56 pmI would suggest trying to flash an unmodified version of the firmware V5.01.01.09R2 and see if that works or not. If not, then it's possible that either we need hacking instructions for newer firmwares, or your hardware might not be compatible with this mod.

content: I tried with V5.01.01.09R2 and that fails too.So, either there is something wrong with my USB sticks, or Siglent has prevented this kind of firmware updates with the new V5.02.01.09R2 version.The USB sticks could be the problem, but I have been using them to update my other Siglent equipment without any trouble, so I don't think there is anything wrong with them, but of course I cannot be 100% sure.

content: Quote from: jas on September 22, 2023, 07:14:14 amI doubt it's the USB stick since you've used them before for the same purpose.I think it's more likely that you have a hardware variation or a firmware "feature" that prevents using other firmwares. My guess is that you would need to wait for a 5.02.xxxx variant firmware to become available before you can mess around. I don't know for sure though. Any thoughts on this@tautech?

You should not be able to flash anything available before Siglent releases new FW package.And, most probably, you shouldn't be able to downgrade...Nonetheless, I'll try to craft a .2. version for the migration FW to see if it works.

content: Quote from: MarkKn on September 23, 2023, 05:56:47 pmThere's no accuracy issue. The 5.5 digit model for the China market is the same exact hardware. I did a comparison test with an SDM3055, and my X-E version was more stable in the smaller digits. I assume because the X-E model has had a lot more burn in time.Here's the results of that test:Note that it's a reference from AliExpress, and while it's a better quality one, I wouldn't bet any money on the cal data. Though it did appear to actually be handwritten.Within 0.5 mV and more stable is pretty awesome performance.

content: From the pictures reports around the SDM3048 / 3055E uses a few cheaper parts than the full 3055. AFAIK the main ones are:1) the input divider with separate resistors instead of a large ceramic divider2) A REF5025 instead of max62253) simpler resistors in the ohm part4) smaller relays (maybe less tolerant to switching with high voltage present)5) smaller size shunts - more thermal INL expected6) no fan : quite, but longer warmup timeSo there is a chance to see a little more long term drift and also reference noise. Still even the cheap version it not that bad and well capable of 5.5. digits.

content: It makes sense to get 3045 like accuracy for the 3055E, because they are essentially the same hardware. There are still different ranges and thus not direct 1:1 copy, especially for the fixed part and the 3045 can have the odd change of actual range inside it's SW set ranges. Using the correct ranges can give a slight step up, but often not much.It is only for the noise (excepts for the reference part) and speed that the 3055E should be essentially like the full 3055.

content: The latest SDM3055X-E version is actually V2.01.01.15R1, released 2023-04-27. The previous release was V2.01.01.12 (2021-08-05)According to the 3045x firmware version history, read and write optimizations have been done in version 1.01.01.25 released on 2021/7/8. Siglent advice is to upgrade to the latest firmware to avoid memory corruptions and the dead boot problem. Then logically those optimizations should solve this problem.But interestingly read and write optimizations were probably present in the SDM3055x-E firmware version 2.01.01.12 (2021-08-05) because this version went out one month after the 3045X release that include those optimizations. But it is not explicitly indicated in the 2.01.01.12 release notes. Neither in the 2.01.01.15R1 version.But i got a dead boot with 2.01.01.12. I've just upgraded to V2.01.01.15R1 now in the hope to not have a new dead boot.As a side note the boot duration is still very long... the same than with previous version (around 17 seconds).According to this video the boot duration is even worse on the SDM3055 with around 24 seconds. Compared to other brands it's really too long, and annoying...https://youtu.be/0wXZ5IezdP0?t=478

content: Quote from: StoneR on April 05, 2025, 08:15:34 pmThat entire line of thought is a waste of time. Boot duration is an absolutely meaningless concern. Your meter needsat least 30 minutes warmupto meet specs. Who cares if it's 30 seconds or 3 seconds to turn on if you have to leave it running to warm up?Anyway, the recovery package for the 3045X still works even if you've upgraded to the 3055X-E. After recovering to 3045X, you can upgrade to 3055X-E again.

content: I do not agree here. For most works there is no need to wait for the 30 minutes warmup period. The precision loss is not so large.Second, some works do not need absolute measurements, but only relative measurements, or an absolute low precision measurement. In this case,the warmup is not mandatory because a relative reference can be taken just before the measurement ; or because the needed precision is low.If the warmup period was so important on multimeters, then they would be all fitted with a standby mode, like can be seen on most frequency meters where analog electronics and time reference are always powered to avoid the preheating time.Anyway, i don't like this long boot duration. Since i got this Siglent multimeter i added a handeld multimeter on the bench to avoid loosing time for fast checks or repairs. And finally because of its slow boot the Siglent is used only 10% of the time. Nice and comfortable display, but so slow to boot...Bare-metal firmware is the way to go i think for entry level to mid range multimeters, Linux boot is way too slow. Leaving a multimeter on all the day is not an option when the lab is only used from time to time."After recovering to 3045X, you can upgrade to 3055X-E again."Yes it works.

For one thing I can usually find them since they don't move around or get buried. Also the batteries are never dead. I have three bench meters with permanent homes and I often use them for a quick measurement like a battery where the last few counts or ppm don't matter.

But of my three one has standby and is accurate immediately, one boots in 2 seconds and is also amazingly accurate immediately (low tempco) and the third doesn't actually boot at all but needs an hour to settle down to spec completely. I suppose the boot times are just the consequence of the new meters having all the extra functionality. But this just underscores the real need to have at least a half-dozen DMMs. You just can't make do with less.

The problem with Linux is that much of the developement happens on rather fast PCs and parts are used also for the smaller much slower systems.There can be a good reason for the somewhat longer boot time with a DMM:A good DMM should do a self test on boot up and this test does need time. In addition to the actual time for the tests one may have to wait some time for the meter to somewhat stabilize before one can do a stringent test.

content: The old HPAK 34401As boot up quickly, but take some time (2~3hrs) to stabilize since they have no fan. All the newer bench types we have (KS34465A, DMM6500, DAQ6510, SDM3065X) take some time to boot up and usually stable within 0.5~1hr and have a fan.Would be a nice if the new bench DMMs had a feature to allow critical internals (like LM399) to remain powered and the display and other functions in limbo or unpowered, but this might not be useful as without the fan on and all DMM circuits powered the internal temperature distribution will change.We measured a temperature of 2~3 C above ambient on some DMMs just at the banana sockets by means of plugging in a dual banana plug supported precision resistor which we had attached a thermistor to measure the resistor temperature. This alone indicates the actual DMM internal banana sockets are higher in temperature and the internals even higher.We're sure this has crossed the minds of the KS and Keithley DMM engineering staff before, as it's an obvious benefit, however this might be the reasoning as to why such hasn't been implemented at least in the higher end precision DMMs.Best

Only the rear power switch disconnects power entirely and if you use that, the cold boot takes 15 seconds or so. These are fanless.

content: Standby mode is possible not only for analog electronics. It is possible to get a faster boot using Suspend to RAM and Resume from RAM even in Linux.For parts temperature it is possible to control that in standby mode without much energy consumption enclosing sensitive measuring components in an small oven. This is used mainly for precision clocks but can be used for anything else.

Keithley and Keysight both are inadequate in this regard. I gave feedback to Keysight through an email conversation, but I sincerely doubt Keysight will do anything. Keithley might. I gave feedback in a meeting with a couple reps from Keithley, and they might do something. I hope so, they seem more open to improvements and keeping their stuff updated than other brands.

So, we need to see if the SDM3055X-E will also have a new HW model. Until then, there is no crossflashing for the newer SDM3045X HW model.And, no need to go after downgrades...Also, regarding the downgrade possibility, I think Siglent support's info that it can be done is somewhat wrong! Or, at least, I hope it is. Because if the upgrade function would allow a lower version number, one could risk flashing the old NAND FW versions in a EMMC (new HW) model...So, the downgrade could be possible BUT only on an old HW model.

The flashing green LED when it is off could suggest a standby mode, but in reality it's nothing of the sort.Then i've sold my 3045X and bought a second hand 34401A.I was not aware of this when i bought the 3045X regardless the Internet readings i did before to buy.Internet is often hiding this kind of problems, except in some rare reviews.Next time i will not buy a product without testing it before.

It integrates nicely with the other equipment which is also worth something to me.Finally, I have to say that the choice offerd on ebay in Austria is very limited. I didn't want to buy a Fluorescent display type meter and since it's a bit hard to test every function on arrival, buying used also comes with some risk which just wasn't worth it to me. In the end, I'd save 200€, which is about 8% of my monthly income - so for about 1,25 days of work I get peace of mind for years to come.I know this might not make sense to people without OCD and objectively I could have made a better deal, but I just wanted it, so I bought it - I hope my explanation above sheds a bit more light on my thinking process.(although now I'm thinking about returning it and sourcing the same model from Amazon, with the hopes of getting an older model since their pricing isn't the best)

Keysight support sucks, and they haven't updated it in years, despite updates absolutely being needed.I also find it exceptionally silly when somebody complains about extra seconds of startup time difference when therequired warmup time is a minimum of 1 hour! If 16 seconds is a major problem for you, buy a handheld meter.

So I figured out how to change it:Use the telnet firmware and...Code:mount -o remount,rw ubi2_0 /usr/bin/siglent/firmdata0cd /usr/bin/siglent/firmdata0sed -i 's/SDM3045X/SDM3055X-E/g' NSP_trends_config_info.xmlthen reboot, and the ID is changed.I tried connecting to TC, and it said:QuoteUpdated that, and:QuoteI like it better this way, because I can have my TC device driver file use separate definitions for both meter versions.Hmmm. I guess the device ID could be whatever you want...QuoteAfter cross flashing and upgrading to the (sadly) latest firmware version, it's still all good:Thanks,Josh

You need a hex editor.

content: I got the nerve up and found a HEX Editor and edited the first line according to the diagram. I triple plus checked it and attached a snip of the edited firmware and the diagram. The 3055x FW download only gave me the single ADS file. When I finally got into the system menu, I can select the external source, but it does not see or give me an option to select a file. Again, the smallest drives I have are two 8gb and three 16gb. I started with the 8gb drive that worked to rescue the meter. None of the drives worked. I ordered a Kingston 4gb drive. It will be here next week. UGH.! Thanks for bearing with me.

content: That's weird. It should work if it worked for recovery. The single ADS file is all you need for firmware upgrade, but you'll need to select the external drive, and then browse. However, the browsing is slightly awkward. Once you select external, you may need to click "lower directory" to find the firmware file.

content: Ok, that got me to the file. It went thru the update process and rebooted. It still appears to be a 3045x. I attached pics after the 3055x update.. Is there another strategy or should I go back to the 09R2 FW.

content: No, it worked- look at the firmware version. The ID won't change unless you do the more difficult trick I mentioned earlier in this thread.Now you can update the firmware to the latest version of the SDM3055X-E without making any modifications to the firwmare.

content: Doesn't the 0000.00indicate 4.5 digits, or am I being a dunce? LOL. I'm looking at the other protocol. I'm not understanding how to initiate Telnet. I've followed online instructions and enabled it in Windows, when initiated, it says that it has been degraded and needs an update. That's where I keep getting stuck. I simply don't understand this kind of stuff. Thanks.

content: You don't need to do that telnet part. The meter is the 3055X-E now, whether the ID says it or not. If you want to make that change too, it will take a little study to learn how to do it. I don't recommend messing with it if you don't have experience using telnet/linux/etc.0000.00 doesn't mean anything, thought that could be 5+1 digits. For example, 1234.56 = 1 is the half digit position, the rest are the remaining 5 digits. 4.5 digits wouldn't have 6 placeholders.

content: No worries; just remember that changing the name is superficial, and you already have the 5.5 digits.

content: Yes, update to the latest. Again, no need to modify upgrade firmwares now that it's converted. You should save your conversion firmware in case you ever need to use the recovery again.
