Ditto. I've noticed that if the checker doesn't quickly change from C1 to C2 the results are skewed. I observed this on both the Nitrate and ULR Phosphorus checkers I own. I have no idea why the checker does this but now if it occurs I restart the test until I get a quick change. I initially thought it might be the clarity of the exterior of the cuvette but I've use a clean microfiber cloth and it still randomly occurs.I’m never experienced a similar issue.
When you do C1 how long does it take to change to C2?, I always rerun C1 if the checker takes more than a couple of seconds to switch to C2.
