I bought a 869s after your tests to use as a second daily use meter next to my trusty Agilent (and a bunch of 5,5 to 7,5 digit benchmeters). I have not regret that. It is a great meter. And thanks to your robustness tests it nice to know that I do not have to be afraid to kill it (that is, for what I do with it, I repair measurement and calibration gear for a living)
Wonder how a Sanwa PC-7000, which is a nearly similar to 869S, will survive such a test. In theory, the modular design of Sanwa supposed to improve the transients.
Brymen 869s for $250 is a bad deal for many reasons 1- unable to read LEDs. 2- resistance Quirk above one megohm even you touch the meter by hand. 3- diodes and capacitor readings are out. 4- taking so much for diodes reading. I don’t know what robust meter means. We don’t test these meters on 1000v or above. The good thing is perfect on voltage and current both AC and DC.
There really is no general answer. If you are asking specifically if the generators I designed and built cause any problems, no they do not. If you are asking if the equipment used for the IEC standards does, in my experience, yes.
Interesting video. I wonder how do you control the generator source impedance. is it limited to some component or it is designed to have a 2 Ohm impedance? Thanks
Hello, good day! Dear Joe, BM 869S multimeter best among those models that you tested. In Your tests is not found Holdpeak model HP890CN with many useful features. The price on Aliexpress 24$. It is really not reliable , you wouldn't call your attention? I assume it can be upgraded as you upgraded ZT102 (AN8002). I ask you to answer my question.
So when you going over the results, is that a range switch changing machine I hear in the background abusing a meter switching back and forth? Good to see it’s repeatable.
I never tire of looking at the brymen's tests. I wish that below of anti spoiler device be an amperimetric clamp but this face makes me doubt xD Nice work!
Sorry, it's not a clamp. I don't really have a need for a clamp meter like you would use for electrical work which is why you don't see me show them. The UT210E was an exception because of the 1mA res. Then it was just begging for some changes.
lol. Well, I started working on it about a week ago and I am not even close. I am thinking maybe next weekend I may have things finished up. So stay tuned.
i have a bm829s and love it. Had to return my first one but this one I have had for 2 years i think. I abuse it and it holds up no problem! Very rugged
Love the Brymen 869s. I bought another high end DMM. A japanese Kyoritsu Kew1062. Their aftersales is excellent. I'm sure they will be happy to send you one for testing! The only drawbacks I do not like are the lcd display quality and the slow resistance refresh rate... other than that, it performs well and meets very high safety specs. No in-depth reviews exist on youtube yet. You could be the first!! www.kew-ltd.co.jp/en/products/detail/00976/
You claim it meets very high safety specs but going to the link you provided, I don't see where it was certified. What agencies certified it? Is it certified for both EMC as well as safety? Do you have the report numbers? Post what you have.
There is no report numbers on the manual. The manual is more detailed as follows: Complied Standards: IEC61010-1, IEC610-2-030, IEC61010-2-033, IEC61010-031 Environmental standards IEC50581 EMC standard: IEC61326-1 Class B Withstand voltage 6.88kv for 5 seconds That's all I have Joe
I don't care what the manual says, without it being certified I don't see how you can claim it meets very high safety specs. Putting a CE mark on your product and adding some verbiage to the manual is not at all the same thing as having it certified. You own the meter. Does it have any marks on it (besides the CE mark)? The second link shows nothing about the safety standards. It's good they at least mention the 61326 standard. It may survive some of my basic tests but then again, maybe not.
I get your point! They just state that it complies with the standards and probably do the testing in house. I'll send you pics of the interior build design.
Your videos are so interesting!!! I learn a lot.
I'm glad you are enjoying them.
Thanks a lot for your great tests, vids and docs!
Good all round workhorse and accurate as well !!
That's the way I see it. Just a good general purpose meter.

Good to hear it worked out for you. It's still my favorite. I wouldn't want a handheld meter that I had to treat with kid gloves.
Where could I get those jack protection caps you had on that brymen amp jacks? 2:25
Thanks Joe I agree good meter Brymen BM869. Whats in that bag!! Can't wait.
Hope to finish it up in another week.

mr. Joe smith, can i ask question ? surge/impulse generator dont give any kind of bad effect to another gears via electricity line at home ?

joe smith Thanks for answering, Mr. Joe Smith.
Interesting video. I wonder how do you control the generator source impedance. is it limited to some component or it is designed to have a 2 Ohm impedance?
Thanks
The impedance in wave shape are set by the output network. Yes, this is by design.
Man what a tease!!!! I know that Brymen under that bag cant be that ugly that you have to keep that bag on it!!!!
She's not a bad looking meter. Stay tuned.

No. If I were life cycling a meter, there would be no reason to ask. They are pretty loud.

Can’t wait to see the new meter hidden under the bag!

After spending the past month binge watching your videos and seeing the BM869 on so many of them its painful to watch it get hurt :P
I damaged my first one shortly after receiving it. Brymen supplied this one for the sole purpose of running these tests.
The Unknown Brymen! Shall it survive Joe's "Gong Show"?!
It's still alive.
good
Ok, then I guess my first multi meter is a bryman! Thanks
