Hello I am getting some mixed results when running multiple tests using my checker. I have tried this twice approx. one week apart.
When doing my tests I fill 2 vials with 10ml water. With one vial I do the complete test and have had a result of 8 pbb. Then I repeat the test using the 2nd vial as the "base" then insert the 1st vial when it prompts for c2 and I get a result of 1 pbb. The 3rd time I do this it comes up as 0 pbb.
First run: 8 pbb
Second run: 1 pbb
Third run: 0 pbb
Both times I did this it produced similar results and now I don't know what to trust?
