Fluke 87V "bricked" when probing own battery
Z-mann:
I discovered the following thing:
When you touch (accidentally!) the positive terminal of the 9V Battery, with the COM lead in VDC Mode - the meter will reset and shows "bAtt" continuously.
I think the Batt.-Voltage detection has failed.
Of course the Battery is full and the fuses are fine.
I downloaded the service manual, and I'm currently looking for a voltage divider (or similar) for measuring the Vbat.
I would appreciate some advice or a hint to look for, in the schematics.
Greetings :-BROKE

Every manual states: Remove probes when opening. No probes, no measuring battery. I don't know why you would even try??? It has low battery indicator for you.

Come on he said "(accidentally!)". The question is it recoverable or did it cause some component damage?

I honestly didn't know that. I do now though. Thanks for the valuable lesson bricked Fluke guy!
NOTE: In the 25 years I've been using DMM's, I've never used the meter on it's own internals. Just for the record.
