Brymen BM-867 teardown pictures
« on: October 21, 2012, 01:39:45 AM »
I got this Brymen multimeter because of the great review Martin did a while ago. It's a beautiful piece of equipment that's highly accurate and responsive, but not exactly cheap, and I didn't really want to open it up because I was afraid that I could mess it up. Until today I got bored and thought what the heck, let's crack it open and see what it's like inside :)

From the little I know about this sort of stuff I reckon this Taiwanese made meter is indeed very well engineered. I'd say it's right up there with the Fluke or Gossen standards, or at least not far off.

I don't know enough to make many more comments on its build but here's a few things I noted:

1. The screws to open up the battery compartment is metal threaded, and captive, so they don't fall out and get lost.
2. The screws to open up the housing are self tappers, but also captive.
3. There are 2 PCB's inside, stacked up through some header pins on both sides. 4 metal threaded screws with washers hold them in place.
4. There are removable plastic blast shields around the input jacks and fuses.
5. There are plastic films between the aluminium shielding and the PCB's.
6. The 2 main chips on the boards are coded BTC 0197 0000 and BTC AD-85-4. I can't find any info about them on the web.
7. The input jacks have split conductors molded inside solid plastic tubes. The splitting is likely for the wrong input plug sensing mechanism.

I don't want to sound spammy but I do have a brand new one of these for sale on eBay. I'm not going to post any direct link to it unless Martin says it's okay, but you should be able to find it with a simple search.

Yes the build quality of those series are excellent, and naturally the features, especially at the BM869 as Full package.
With the BM869 which takes dual thermocouples, I can even compare and keep track among differences of K Type thermocouple probes.   
   
The most important to know is that those meters are designed under an electrician engineer.
Which is a leading mind in Taiwan.

Basically we have some great minds worldwide, those reviews helps us to discover them, and also to motivate our self's to advance, by having them as examples.

Great post...and yes, please feel free to post the eBay link here. I will also start a "Buy and Sell" section on the forum too.
Play, discover, learn and enjoy! (and don't be scared to make mistakes along the way!)
