EEVblog BM786 Multimeter - no resistance reading above ~1k?
(1/1)
gnasirator:
Hi all,

I just recently got me the otherwise great EEVblog meter but now while I was tinkering away I noticed something really odd:
The meter always shows 'OL' when I try to measure resistors > ~1k. I've managed to correctly measure up to 600 Ohms so far but all greater values don't show a value. Has anyone else experienced this?
My firmware version is 78607 and if I set the meter to diode mode and measure the resistors, I do in fact get a voltage reading that somewhat scales with the resistance.

So what could it be? Has anyone experienced a similar thing? What can I do to resolve this issue?
Dave, do you support these meters in any way? I'm happy to set an alarm to midnight and demonstrate via Zoom/Skype to you (living in Germany) ;)

Sounds like your meter is stuck on 600 ohm range.
Do you have autoranging enabled i.e "AUTO" indicator on display?

600 Ohms max on a 60000 count meter? Sounds like somebody disabled auto-ranging...  :popcorn:

(try turning it off and on again)

Thanks. Issue solved! Auto was indeed off. I shouldve maybe read the manual instead of randomly pressing buttons after unboxing it…
