Hey all,
About a month ago I decided that I needed another multimeter for home projects and decided on the Brymen 235. Yesterday I went down to my local watering hole where they were having major issues with their P.A. system. I told my friend, a bartender there, that I'd spend a bit of my Sunday seeing if I could track down some issues. Today I went in, set my multimeter and some basic tools on the stage and started tearing into it, tracing cables and cleaning up the absolute tangled rat's nest that every bar venue sound system turns into. I was about 5 minutes into it when I had to do some acrobatic maneuver in between a tip-toed step and an awkward jump onto the stage, and sure enough I knocked a nearly full pint over onto my meter. Notice that I said nearly full: I was pretty sober, I promise!
Anyway, now the meter is giving me "InEr" on any range other than mA/microA, even after letting the board sit in a bag of rice for a few hours. I'm looking for troubleshooting tips.
I found
https://www.eevblog.com/forum/testgear/what-do-you-think-of-your-eevblog-brymen-bm235-multimeter/50/ This thread which says:
"Input warning detection uses a comparator inside main chip. While A or mA/uA input terminal is without being plugged-in by test lead, the compared signals are from battery voltage and from a fixed voltage around 3.6V. If battery voltage is more than 3.5V, that comparator may misjudge and display “InEr”."
For now I'm going to keep letting it dry out while crossing my fingers, and take it to work tomorrow morning to begin probing around near the input jacks.
