Autorange Brymen BM511? Answered
I have an unusual problem.
My BM511 will not auto-range and readings on VDC are odd.
A 1.5v battery initially shows OL, then 00.61, 001.5 then 0002V as you manually step up through the range of the meter using the 'range' button.
I suspect it has been burnt, either the input protection, bridge or scale divider.
As I do not have a diagram i cannot fault find.
Does anyone have a circuit diagram for the Brymen BM511 DMM.
Thanks in advance.
