Sartail,

Max's clever response is solid advice in response to a very good question. It is very common to see .5CC every time you run the test and, yes, you should ignore it 'til it gets to 1.......then shock.

KurtV indicated in a similar post that he had read that you add one more drop to validate your true reading (which means you would go to zeroCC) and that makes sense to me.
