Often, rules and regulations have requirements for data completeness (i.e., how many valid data records during a measurement period as a percentage) that must be met in order for a measurement period to be considered valid. QuantAQ does not claim any data completeness guarantee.

In normal use, data completion is very high, often near 100% at the 1-minute interval. To calculate data completeness, simply divide the number of valid data records by the total number of available minutes during the period of measurement. For example, if you are trying to determine the data completeness for a single day, the math would be:

# Compute the data completeness

data completeness = Number of valid data records / 1440
