I'm sure some of you have done this before. On some of the checkers there's a wait period before getting the result. You put it down and do something else and by the time you remember to check the checker turned off already. To avoid wasting reagents you fill the other vial with tank water and just swap with the one with reagent when it ask for C2. I'm sure accuracy will be affected if it was hours in between but what if it's just a few minutes.
