Well in the instruction from what I understand you poor the powder into vial right after c2 is displayed when it's dissolved you add to unit and hold botton tell 3:00 countdown starts.

My instructions say to mix the cuvette for 2 minutes, then start the 3 min countdown.

Mine don't neither do any videos I've watched

What I'm trying to say is they say to replace vial before 3 minute count down

'xactly

No holding the cuvette outside the tester and 're-mix a bit more' before adding to the tester.

Mix, insert, hold button to start 3min timer
