Thanks for the time J.
I just checked and my bluelabs pen may be whacked too. It failed
to calibrate. ...but it did seem to get the standard fluid's pH correct.
Onward and upward,

Rehydrate in tap water for 24 hours.
If that doesn't work try some KCI solution.
Then try to cal.
Also replace batteries and double check.
Have you been keeping the sponge in the cap saturated with water or KCI to keep the probe from drying?
