Hello All,
I got a Kh director at the beginning of May and everything was great, but after 2-3 weeks I started having problems with measurement. I take 2 measurements a day.
When kH is 8 I get measurements like 11 or 5. :/
After cleaning and calibrating the dosing heads 2 times, I realized this. The waste water dosing head cannot completely empty the measuring cell. The same goes for the "sample water" tube too. Always remains test water in cell and tubes....
Even with the "Empty measurement cell" command, the test water in the hoses cannot be completely drained.
I think that the reason for the deviation of the tests is the remaining water, but why do you think the 1st and 3rd dosing heads cannot empty this water?
Has anything like this happened to anyone before?
