@joeqsmith @EEVblog is 78911 the most recent firmware?
I got a new BM789 from @Welectron with FW 78908
They have no newer fw in stock and can't update the firmware. So, I'm sitting here with a shiny new DMM with buggy firmware....
They said they'll contact Brymen and I might send it to them (Brymen) for update. Not really what I want to do with a new device, tbh.
I hope they'll find a customer-friendly solution.
EDIT: Just to clarify, I don't want to blame Welectron for that Problem, I'm sure they'll give their best to solve this :-)
