Brymen 869S vs EEVblog BM786?

<< < (3/5) > >>

ElectricPower:
uCurrent Gold is sold out in eevblog store. Somebody that knows when i can buy this?

ElectricPower:
I couldn't wait. BM786 is now ordered :)

J-R:
I like the 121GW for Bluetooth, long battery life and you can backup/restore both the firmware & calibration.  A recent firmware hack to disable mode selection memory is handy.
Selector switch is nice and light. You can adjust the display contrast.  The secondary display can have a few goodies displayed: internal temperature, burden voltage, time, date, battery level. You can turn the beep on and off with a couple button presses.

However, I have not found the mA display via the A shunt to be particularly great, since the accuracy suffers.  The BM869s can generally provide just as good mA values using the A range (1mA is no problem).  Ultimately, I can get far better numbers from my high-end bench meters via the mV function.

It's absolutely true that UEi has never been at the same level as Brymen from a hardware performance perspective, but on the flip side Brymen is pretty well stuck in a rut.  Their software is ancient, the BM78x series didn't really bring anything new to the table compared to the BM869s other than a slightly smaller form factor, NCV detection and AutoV/LoZ.  They also play games like many other companies by limiting features to segment the products (handheld vs. clamp for example).

My main point: if you already have a BM869s on your bench, then why get the BM786?  They both have poor battery life at about 100 hours and have a lot of overlap.
But otherwise it does what it says, no problem there.  Although my early BM789 has a list of problems, such as beeper dies with the magnet attached and it makes a clicking noise when you turn it on.  Luckily I dodged a couple other major issues before and after my revision number.


I stopped watching Joe's videos many years ago as I eventually realized few to none of his tests were of any interest to me.  This was back when I also watched lots of shootout videos and bought what was recommended.  I ended up with a bunch of equipment that I didn't like and had to go buy the equipment I really wanted.


The uCurrent Gold has been out of stock for quite some time from I've seen.  I managed to snag one about 2 years ago, but use the much more expensive CurrentRanger instead due to the handy built-in display: https://lowpowerlab.com/shop/product/152
Again, a you may be surprised at what you can do via the mV range on your existing DMM...

ElectricPower:
A little update.

BM786 fell down in my mailbox today.

A short unbox:











BILLPOD:
ElectricPower, are the probes in the last picture what came with the meter?
They look like Probemasters. :scared:
