I just wanted to say I picked one of these up and they have fixed quite a few of your complaints in the firmware! The speed like you’ve mentioned in the comments is a lot faster now and the power light is no longer used as a light house. Thanks for the awesome review as always!
Truly entertaining video, I'm thrilled there is such an abundance of new material posted each week.
Great video as usual...I actually find myself checking UA-cam every day hoping to find a new video...really love the repairs...you make them look easy which is a bit deceiving because when I get a broken device I go in to it thinking easy-peazy until I actually start probing around !! You are definitely good at your craft !
Very nice video, you always do a great job. A little while back I got a Keysight 34461A and I was a bit surprised how their front panel layouts are almost the same.
Perfect review! Thanks. I'll get today SDM3054X
I had a piece of equipment that also had an "eye searing" LED and I thought about playing around with the current limiting of the LED but found a much more elegant solution - I put a small piece of good old masking tape behind the front panel and in front of the LED; the tape attenuated the brightness to a comfortable level and no circuit surgery was needed.
Thanks, been waiting for this review for awhile.
I appreciate the informative video! You helped me make my decision on what bench top multimeter to purchase. Thank you again for the super informative video! Keep up the great work!!!!
As usual, I enjoy watching your videos even though the material mostly go way over my head. Your method of explanation makes the watcher feel like he understands. Even though it is way below you, I would like to see you look at a diy oscilloscope that YJE produces. It is for beginners (DSO138) but it would be nice to see you review it ,explain the schematic they show, and take a look at things that the purchaser could do to it to make it work better and with less noise.
Thanks again for your great videos. As I said most of it goes right over my head, but your explanation and your way of presenting the information is greatly appreciated.
Thanks.
Thanks Sir for enlightening us about this instrument, came to like this product indeed
Great video as always. Not sure if I would put one of these on my bench though.. that update speed!!
Thanks for the video. Great information and just the right amount of detail. Good work! I am considering purchasing this unit and was wondering if you were aware of any significant changes in the last 2 years to address some of the concerns you mention. Thanks again!
WE MISS YOU, Shariar!!
An interesting video as always, especially for those who can't afford Agilent/Keithley prices. It would be interesting to see a side by side comparison to the Rigol DM3058E which has a similar price point. Nice display but seemed rather slow in auto range mode.
I bought the unit from Amazon based on your review. I also tried to install the SW basically for capturing screens in my PC and I get the same error connecting via USB as well as Ethernet. My message read Failed to connect (not very useful). I have tried installing all sort of National Instruments SW to get this to work to no avail.
Excellent as always! Would you consider reviewing the UNI-T 8804?
My metter switching the relay like crazy between testing on resistance testing and sometimes shows resistance on the mega ohms range on open leads. mine also shows 50hz on open leads on the frequency testing. do you have this king of problems?
Very good, thanks again!
Could someone please let me know why it is beneficial to have exposed PCB traces for sensitive analogue voltages? (mentioned @ 13'09")
I would like to see a detailed tutorial on dual slope conversion
When off is normal for the power button to blink green?
what ADC and reference is it using?
Did you try to stick the warranty void sticker back on? I have seen quite some of them lately that just wont stick anymore after dried out for a few minutes in air. Regarding the little board with the MOV, I see lots of those for cost saving purposes. All units of a manufacturer have the same boards, and there is a couple of them for various countries filtering regulations, and you stick in the cheapest you can get away with.
Hi. I would use better leads to test resistance just in case of self heating.
Could you please add a link to your DMM Check circuitry? Many thanks!
I have looked all over for the pointer you use. unless you know where to buy it I think someone may have made it in a machine shop.
What is Residual Resistance ? How to Zero it out ? Whats the use of Relative in Resistance Measurement ? I have never seen such a thing in my hand held Fluke multimeter. Hows is this instrument in terns of Counts and PPM Drift ? I am planning to buy one... Thanks
Nice, would like to see a comparison with the Rigol DM3058E that it is the same price.
This design is very interesting. They put a BeagleBone Black to their own design and added some on-board flash to it (you probably messed up FLASH and RAM chips, but don't care). Are they using a linux system in the background, or why do they keep it in standby instead of switching it off?
This multimeter is really slow even for me,
anyway this is a good and professional review (as usual!), thank you
Thank you!
I hope that you please wont to reply to this question.:
Is there any great reason for buying a A-name brand over i.e. the Siglent?
Try Google Translate on your phone by taking a Picture of message.
I got 'Manual 200 mVDC Error'
Automatic thumbs up, just because of the cat.
Nice, but from 43:08 - in center there is +1K, upper is +1.0001K and lower... I think, must be 0.9999K ?
Looks like a nice meter with a nice display and not a bad price but its just far too slow what a shame. This is a great review tho very nice work as always.
I don’t think it’s too slow. I have one of the newer ones and I’ve always been happy with it.
There was a firmware upgrade a few months after I released this video where they improved the speed drastically.
Please review an electrometer / nanovoltmeter! I want to see triax measurement setup, and see gate leakage measurements. :) Please?
Shahriar, when you stress tested the cables at 5000V, maybe you should have turned the lights out to really check the dielectric breakdown, a blue spark or aura may have been witnessed. Sorry, didn't need to tell you that did I. lol
Would have looked good for the video too.
Like your Cat by the way, what tyoe is it? Persian?
What is operation frequency of the cat?
Roughly 0.2 hairballs per month. :)
use GOLD PLATED probe tips , it wont miss beeps in continuity test
is that a metallic pen you're poking at the board?
I'm not the only one that noticed.
for those who do not understand English, not having subtitles does not allow a translation. Why aren't they enabled?
I love new gear on my bench, but I don't see anything in this review that would make me abandon my ~15 y/o HP 34401A in favor of this Siglent. Yes, it measures capacitance, but I would use an LCR meter for that measurement anyway, which also does inductance. Measurement speed is too slow. The PC remote measurement software is hilariously bad, and sadly typical of many Chinese products. They rush to market without proper development and debugging, and customers are forced to act as an arm of their R&D department instead of buying an instrument that enhances productivity. In a global marketplace like we see today, there's really no excuse for software and user manuals as bad as the Chinese put out when there are plenty of talented coders and tech writers in the world who would respond to the right financial incentives. [/soapbox] Anyway, thanks for another complete and informative review, Shahriar!
Great review, this meter is way too slow for me!
👍👍
I see what you did with high voltage cat testing :)
Lets do some more repairs.
21:32 one second delay, very slow. their scopes does the same thing.
Nice but seems lacking to me for the price asked. Rather put that money into a nice handheld with PC interface.
1. More cats. CHECK
2. More frequent videos, CHECK
3. It takes it's time to update? Little bit slow? Man, that's slooooow :) I understand that having Keithley meters spoils, but man, that's too slow. Even in fast mode it's still very slow, so seems limitation is from GUI refresh on LCD.
4. Would be cool to have just few words and closeup of used ADC and voltage reference used in meter. That will tell us more about stability/long-term performance, than most of specs in datasheet :)
5. Bar-graph display seems broken, starts from screen edge, not scale edge ^_^. Also in ohms bar-graph is starting not at zero, allowing negative resistance? :)
One of things you could improve for future - to shot some hi-res photos of reviewed gear and internals and upload some pic hosting, or in your website article. Sometimes having such photos is priceless for repairs / hacks ;)
A Siglent DMM with extra, external cat-hode! 2:30
I am SOOO bummed I bought a rigol. UGH>
That's one slow DMM.
I don't think this is worth half a Truevolt, personally.
If the budget is that tight I'd still just get an older brand name meter and replicate the graphics functions in software on the PC.
Those Chinese firms are snapping at the heels of the big boys, no doubt about it. But in offering more features they had to increase their price from like 1/10th of a top brand to more like 1/2. I don't think you get enough quality for that kind of money.
Good review though, at least now I know I have no interest in this product, thanks!
Given the components, that company should lower the price to around $100-150 range
First guise omg first.
This meter is a direct knockoff of the Agilent 34461A Multimeter. Watch David Jones video EEVblog #489 for a direct comparison. The reviews are basically the same just the bloody accents are different. They just basically copied this meter button for button screen for screen. I don't think that Agilent would rebrand their meter for Siglent, or would they? I would like to say great review, but it just disturbed me what some manufactures would do to make a buck.
ever seen a function generator? they are mostly copies of each others... with that logic lambos are copies of the original ford... everyone copies thats what brings price, and quality, down.
Some Lecroy scopes are re-branded IWATSU , everyone does it
@@EdwinFairchildLecroy also re-brand Siglent DDS generators and low grade oscilloscopes.
you need to buy some better equipment to do these tests
220000 counts 😑
