False Reads are handled by checking back any that are false to when they were first "seen" by an auditor.

Sometimes a false read goes on and on, never cleans because there wasn't anything there in the first place.

Find when and where somebody thought it read when it didn't. Can ask, "Who said you had an ______ reading when you didn't have one?"

Also check Protest, Invalidate and Suppress to clean up a false read.
