content: Hello everyone i'm new to the forum, just got back into electronics again after a long time and joined a couple months ago. I just received a Siglent SDM3055 multimeter. I bought this from Tequipment.net and waited a couple months for its arrival after trying to decide to go for this or the Rigol. So today i FINALLY receive my multimeter and i instantly pull it out of the box to check out its over all beauty and magical color screen. I set the voltage setting to 110v and plug it in touch the power button and WHOOOAH there it is the multimeter starts up and im looking at an array of colors and inverted numbers on the display! well at this moment i'm pretty happy i got what i wanted just in time for christmas cant wait to try it out on something to see that 5 1/2 digit display do its job. So about an hour later after i finish up some other work i'm ready to connect some test leads and start learning some of the possible functions. So i reach for the power button, push it and wait only to see a white screen that says "Siglent Technologies" stay on permanently. I haven't as much as tested a battery and this thing is basically junk. I know it took a while to get these here, ( I live in new york and there's a warehouse in Ohio) and im sure there are some of you checking these out but obviously they have not gotten the bugs out of these yet. I called Tequipment.net tech support and have not gotten a phone call back yet and when i did speak with them he told me they're only a distributor and i need to contact Siglent. I emailed scott.rocco@siglent.com earlier today hoping for a quick response. So if anyone else out there is thinking of making this multimeter their new christmas gift for themselves, maybe its best you wait or grab something else for now. Ill be sure to keep this thread updated with hopefully some kind of review of the product if i can get a replacement unit or this one working again.

content: I also have a SDM3055, and I also had some trouble with my first unit as you can read here:https://www.eevblog.com/forum/testgear/need-help-with-siglent-sdm3055/.The factory installed firmware was so dangerously buggy, it made the Multimeter lock up. However, with the help from my dealer and a Siglent engineer we could figure out the problem rather quickly, they fixed the firmware and also I got a replacement unit in no time.So, again, I advise people to immediately update the firmware on their units to the most recent one from the Siglent website before playing around with the Multimeter!Mine came with 1.01.01.08R1, now it is on 1.01.01.09.Wish you good luck with yours!Marty

content: Martyd where did you find the firmware? I checked Siglents website and I see firmware for everything except the DGM3000 series. I hardly had a chance to even update the firmware I only got one sucessful startup before it stopped working.

content: Although it may be Siglent's fault, it's still Tequipment's responsibility to sort it out as they sold it to you. Always bear this in mind when you buy something: deal with the vendor, rather than the manufacturer.It sounds like a problem with the firmware to me.

content: The new SDM3055A that I have had for only a few days has Firmware 1.01.01.08R1.It seems this was a revised version from the initial SDM3055 release firmware.However there is a later version 1.01.01.09 on the Siglent firmware download page:http://www.siglent.com/ENs/gjjrj-xq.aspx?id=978&tid=15It is a 3.2 Mb .rar file that needs to upacked after download.EDITThis new firmware is suitable for 3055 and 3055A.

content: Has anybody had a chance to compare the Siglent SDM3055 to the Rigol DM3058E? The color screen on the Siglent is sure tempting, but given some of the problems reported here (and Rigol's more mature reputation) I'm tempted to go with the "safe" Rigol choice. Esp. in the absence of any real reviews or comparisons of the Siglent.Re the Siglent, specs I can read, but I'd especially like to know:* Does it have a fan? (I hate fan noise.)* Is the continuity test fast & loud? (Supposedly the Rigol's is fast, but hard to hear - this is so easy, yet so many DMMs do it poorly)* UI and ease of use - I don't want to have to refer to a manual all the time, or wade thru layers of menus* RS-232/USB output: Do I have to use Siglent's software or can I use a dumb terminal? (much prefer the latter - then I can write my own software much more easily)* Does Siglent have anything similar to Rigol's "any sensor" mode? (I'd like to be able to hook up the output from a load cell amplifier, give it an offset and gain in volts/gram, and then see an output in gram force...)The DM3058E is about 7 years old now - I'd think Rigol would be getting ready with a replacement model by now (if only to compete with Siglent's color screen...). Any rumors?

content: Sorry I can't answer all your questions.Fan cooled and barely heard at arms length.Continuity fast but not loud, could be a little louder IMO.I find the UI intuitive and because of this I have yet to look at the Full manual.User manual:http://www.siglentamerica.com/USA_website_2014/Documents/UserManual/SDM3055x_UserManual_UM06035-E02A.pdf

content: Quote from: nctnico on February 03, 2015, 01:27:25 amMore and more? Older equipment has far more and far noisier fans than modern equipment. Modern instruments can be quite annoying, but they are far less annoying than old stuff. I do agree that quiet is good, and that modern instruments should have quieter fans, but lets be realistic about historic trends,

content: Well something simple like a DMM or a frequency counter shouldn't need a fan. The same goes for a frequency generator. If they are more clever about the thermal design (read: use the casing as a heatsink) then fans can be omitted in many cases.

content: I'm having the same issue with my Siglent SDM3055. I also received my meter from TEquipment.net back in December after waiting almost a month. I've used it a couple of times without an issue, but today when I turned it got stuck on the Siglent splash screen. I've tried unplugging it a couple of times but the same thing. Not good!

content: Old thread but.. Just had this Happen to my SDM3055..Sent this to info@siglent.com. Better contact? obviously I can call Monday..A week or so ago my SMD3055 crashed while in chart mode and I didn’t think anything of it because I was done using it at the time.. I turned it off and that was that.. When I turned it on today, it doesn’t start up. It just stays on the boot screen… then after quite a while goes black, but the screen backlight is on. I’ve read that this is an issue with older firmware and requires it be repair. Hope that isn’t the case because of course I need it to work now!! Because I can’t boot it I don’t know what firmware is on it.. But I know I have updated it since purchase at some point.Purchased June 27/2016.Of course this happens on a Friday!!
