- You wanted to see it, so here it is. Unlike Dave's reviews of the Xtra and Energy, this Gossen will be subjected to the same tests as all the meters before it. So you Gossen fan boys best turn the channel.
"Features in detail Three Connector Jacks with Automatic Blocking Sockets (ABS)((Patented (patent no. DE 10 2005 062 624, US 7,439,725)) All current ranges are implemented via a single connector jack which prevents any possibility of operator error. Beyond this, the automatic blocking sockets prevent incorrect connection of the measurement cables, as well as selection of the wrong measured quantity.
Danger to the user, the instrument and the device under test resulting from operator error is thus ruled out. Overload Protection The instrument is safeguarded for up to 1000 V in all measuring functions by overload protection. Voltages of greater than 1000 V and current of greater than 10 or 16 A are indicated acoustically. Dangerous contact voltages are indicated when the 1 kHz lowpass filter is activated." - Věda a technologie
I've just discovered your channel, and I would like thank you for amazing content. Came when was searching for a reliable multi-meter, ended with just with browsing everything and enjoying every minute of it. Testing done right, you don't see it anymore even in the most companies building industrial equipment. Thank you.
Hello Don, thanks and I'm glad you are enjoying the channel.
Finally, a gossen meter under a proper testing, thanks.
Thank you! Looking forward to the next one!
Great! Both a multimeter and a theremin for the same price. Going to be interesting to see why. Great video as always.
Exactly what I wrote in my emails, it's a theremin. No one knew what I was talking about.
joe smith haha. they probably just have no sense of humor:)
To clarify, those were emails to friends, not Gossen. Strange still that they had no idea what a theremin was so I had to explain a proximity sensor.
joe smith ooooh ok. i got a chance to mess with a "professional" theramin once. it was cool but im not exactly sure what about it made it processional.
I saw one played as a child. It was pretty cool.
BTW, I have attempted to keep Metrawatt informed. I provided them with the details of what will be in part 2. Basically, I want to know if this is a defective meter and needs to be returned for service. Sadly there has been no response.
I cannot understand why Gossen behaved like this; they must have a terrible PR policy.
@@lykortos4827 I believe some of the fault is with the US distributor who out right lied to Gossen about our discussion. That pretty much set the tone moving forward. Oddly enough, if you look up this meter, you will find they changed the name of the product. I wrote them to see if they had made any improvements to the hardware but they would not respond. Someone wrote me how Gossen had actually addressed the problems by adding a shield like I had shown however, I have no confirmation of that. Not at all what I was expecting based on all the hype surrounding the brand.
Can you test some FLIR dm meters
Morning Mr Smith
Thank you for the videos, after comparing meter specs.. I decided to purchase the brymen BM 257s.....
In my line of work as a Electrical Engineer.. I do both electrical repairs in residential environments and do also car electrical customizations this should work perfect for me..
Thanks..
One more thing..
You calibrate meters as I see.... Can I send you mine as needed... Yes of course, I have to pay you... Lol....
Let me know...
I do not calibrate meters, nor do I offer any services or products for sale. I also don't accept donations. There are many cal labs in the US if that is something you really require, perhaps for your ISO cert.
I have not looked at the 257s but it seems like a nice little meter. All of the Brymen products I have looked at have done very well in my tests.
I also purchased a BM257s partly based on Joe's reviews. It has become my work multimeter, keeping arcade games and pinball machines alive and well.
I liked that meter so much that I turned around and ordered a BM829s for my home. As far as I can tell, the BM829s is very similar to the BM869s, except that it is 10,000 count.
Very happy with both.
17:17 I cannot quite recall, but that "phenomena spook" reminded me of the Keysight U1272A EMC issue discussed on EEVBlog #933 (as well as the followup #987). I'm not too sure what's the issue in regards to what exactly happened with your specific Metrahit DMM, but I'll stay tuned.
Notice what happened a few times when I attempted to null the meter?
Okay, now I just noticed this appeared a tad bit earlier at ~16:57. I'm still probably not catching it early enough in the video. Eager to see the voltage transient test and high current testing in the upcoming tests.
EDIT: Ah! I think I now see it ~09:27! I just had to watch it about 3 more times in its entirety. My apologies as I was one of those BSEE students who had to study 4-5 hours for every 1 hour of instruction (learning disability).
Part 2 will just be about this one problem.
Dyaxxis is it static energy of ur body because i saw a video on another chanal i thing electroboom about that mmm?
👍👍
Спасибо большое за информацию.
Добро пожаловать.
It looked like the UniT had some "wiggle" too?
Gratz on the 2K, should be far more though for your no nonsense, clear cut vids.
Perhaps we look at it as 2.3K people know their arse from their elbow!
yes, but it wasn't as bad as the gossen, the lowest value for the gossen was 0.580mv and the highest 1.225mv for a 0.965mv reading, on the uni-t was l0.933mv and h0.953mv for a 0.946mv reading.
You haven't seen anything yet!
Too funny.
For $800+, I'd expect perfection right out of the box. Can't wait for Part 2. Continually feeling more and more vindicated for buying my Bryman BM869s for $230.00! Give me a BM869s with Fluke 289/Gossen Metrawatt M248B features with BlueTooth and Bryman's aggressive pricing and I'd be in meter heaven...
What's a BM289s? I would not mind paying more for a better handheld meter but I have yet to find one I like more than the BM869s.
Lord.... Some days my aging mind just seems to randomize numbers and letters. I corrected to BM869s.... duh... Besides, collecting so many meters all these years, the numbers seem to run together after awhile.

You never know when you're going to need a spare, or an "I don't care" meter to loan to friends and family...Or leave a particular meter attached to a project for a year or more.
Perhaps I should seek profession help from the medical community or join Meters Anonymous.
HAHA Welcome to the club! I figured for $230, it's got to be the 869s but then new meters come out all the time.
You got your new favorite meter, didn't you? At least until HIOKI DT4282 arrives... ;)
btw those lower Metrahit models autoranges a lot faster because of less ranges to go through.
Personally, I was hoping more viewers would have voted for the HIOKI because I have a good feeling that meter would survive with no drama. It's still missing the two TC inputs which is why I went with the Brymen in the first place.
This is the slowest autorange meter I have ever seen. My antique HP34401A is well under a second. But the Gossen manual did state 8 seconds so if someone did not read the manual before buying, that's on them. I had a good idea what to expect. Still it was a bit of a shock to see it really was that slow.
I think this is more for labs or scientistic use where user does not switch ranges very often... They would measure voltage for hours and use computer to capture data.. That lower model would be more interesting for us...
Us meaning you? Or do you feel you speak for everyone? You could always get a lower model and review it for the "us" group. I'll run this one for the few remaining in the others group.
Could be :) MetraHit Extra would be more than enough for me..
04:50 : You can't argue with the build quality of this thing...
05:50 : I don't understand why meter manufacturers make it such a pain to replace the batteries esp. on cheap meters. The Gossen is quite a bit better in that respect, having a separate, easily accessible compartment. I hate those meters that a) require a 9v battery and b) you need sth. like 10 mins to replace it because you have to dismantle the whole meter in order to access it.10:40 : What is the maximum temperature the Gossen can measure?
11:06 : I've noticed that on most meters when the backlight is on you can't necessarily see what position your rotary switch is in. The Gossen has a slightly more visible dial but still not enough. It would be good if they had backlighting on the entire instrument panel, including the lead sockets. Alternatively, as small external light illuminating the panel would do the job.
12:00 : What is the reason the meter takes so long to settle? Isn't it a good thing, i.e. regarding precision, that it takes longer rather than shorter time?
I just noticed this post was flagged at spam. This meter has one of the worse battery life of the meters I have looked at. It has support for an external pack for that reason. You better be able to change out the batteries fast because you will be doing it often!
I like your idea on having a backlight for the rotary switch. I've never seen it.
Many of the meters I have looked at are slow to settle and auto range. This meter is so unstable out of the box, forget precision. You can't use it. Move your hand near it and off into the weeds it goes.
I wouldn't take much to improve this meter but this is something Gossen should have done, not a customer.
The gossen is a meter that dave would be kissing, so i did expect it to perform better than all of the others, but the resistance did take a week and a half to sort itself out.:-(
The 300khz test result just seemed unimpressive.
And the mad field effect of your hand with 60hz on it really supprised me, it's almost like there is no sheilding in it.
I don't get that from my £5 specials lol.
The display was tiny, i know it was due to it's resolution, but was it not possible to continue with another line showing the remainder of the reading, perhaps im mad :)
Your jumping to conclusions about the 60Hz. Wait until part 2 where I will show just how bad this problem really is.
Yes i do, but it shows that your videos make me think.
Thats good, even when im wrong (all the time) lol.
LOL. So just to be perfectly honest, I have yet to take the meter apart and I still do not fully understand what is going on myself.
Strange... My Metrahit PM Xtra came in a nice padded plastic case. And this more expensive model comes in a plain carboard box? No case?
It was double boxed. You get the rubber boot. If you want a hanger or anything else, you will have to pay extra.
first strong dislike is the tiny main display. its doesnt matter how good the thing is if you cant see it.
Sound like a fluke gsm nightmare on mV scale . xD
Try made a call on mV scale too.
oh man. please release the next video....please....
LOL Part 2 should be up next week.
None test multi meters like Joe!
Personally, I would welcome it!
How much did you pay for this meter?
With tax, about nine. I imagine with the cable and software, a k.
Wow, you must be rich. I could never imagine paying that much for something I planned on trying to destroy.
The term rich is relative. The uneducated in this country with a one pack a day habit will spend $3000 a year to destroy their lungs. I have had friends die from lung cancer. People have drug habits that raise the cost of destroying your body by a significant amount. My meter testing is well under a pack a day habit. We all have choices. The meters I damage do little to effect my friends and family in a negative way. It is nothing like watching the people you know destroy themselves with their own bad habits. So don't preach to me about how I use my resources.
I'm not preaching to you. I'm not sure how you even got that from my statement. The thought that I should be telling you how to spend your money never even entered my mind.
That's good because there is nothing worse than people who go around preaching about how I choose to spend the money I earn working at my job, because they have no money after they spent theirs on alcohol, cigarettes, drugs, cable TV, cell phones, video games, $100,000 watches (from the last EEVBLOG videos). It's all about choices and for now I am having some fun benchmarking a few meters. Could these resources be used for something more productive? I am sure that the vast majority of the population would say yes. But for the few people who are interested in seeing this data, you are more than welcome to follow along at my expense.
check Uni-t ut195DS
I need it!!😍😍😍 for free😁😁😁
You may want it but I doubt you need it. This is not the free give away channel. Try some of the large channels for free stuff.
just kidding sir!! thanks for such a nice content!! is ut181a good for use if we can say in overall performance like precision, reliability, calibration, quality...
@@partscience I would have no idea if the UT181A would meet anyone's needs besides my own. I can tell you that during the winter months, our house will become very dry and ESD is a problem. I can tell you that the events I get from toughing door knobs and such in the house cause more pain than the little gas grill igniter that damaged the UT181A. I can also tell you that I would not want any meter that can't handle some basic transients without becoming damaged. I had that with my first Fluke.
If I were going to give away free meters, you can guess the brand I would promote....
Sir THANKS for THAT!! I want to buy and go for that from UT71C... I don't have extreme environment conditions... I was just telling about its calibration, accuracy, sampling quality, fuses, material quality etc... you are telling me about the stamina to beat these... I think industrial multimeters from Uni-T may or not overcome them...
Metrahit
Watch again or just read the title. It's an Ultra, not a Metrahit.
