What's interesting is, it took that long before I ever had a chance to
store it! I first used it the other day. I placed it on 4.0 PH buffer
solution and it took a good 15-20 minutes to settle, then I calibrated it.
Did the same for the 7.0 buffer. Then I did tests with my must during the
course of the evening, rinsing and placing the probe back in the buffer
solution in-between tests.
All tests took about 20-30 minutes before the meter provided a steady
reading. Do I have a "sick" electrode?
