Recently bought a Milwaukee MW102 and I have a question on using it.
I sent this question to their tech support but didn't get anything back.
Meter is calibrated as suggested on the manual.
When I place the PH probe in sample with the temp probe, I stir for 5 sec with the PH probe and leave it alone to complete the reading. Display starts showing 6.5 (example) and slowly increases and after 30s it is at 7.2 when the reading is shown to be completed. Thing is, leaving the probe in the sample further will make it re-read the PH and it keeps increasing, specially if I stir a bit like the first time. After several reading cycles, it reaches 7.9
So what is the deal with this thing? Is the first reading the actual PH (7.2) or do I need to keep stirring the probe in the sample during all reading process?
