APEX pH -- Anyone have a clue?

[Mike Yasin]

So I took my probe out, cleaned it (it was a bit nasty) and thought I'd recalibrate it. you can see that it read the solution @ 7.3 and 10.2, but then got this when I rinsed and put it back in the sump.

Calibration now doesn't read anything I throw at it. restrating or resetting the brain does nothingAnyone have any ideas?

I had this happen and restarting it a few times helped resolve this.

I also remember recalibrating it again.

Thanks-- let's hope that is something that will work for me. I'll keep poking it with a tooth pick and see if I can get it moving.

Also, try tilting the probe. I think sometimes an air bubble or something can get in and cause some weird readings too.

3 more tries and it finally reset the probe. Thanks for the tip!
