One sample consists of all the quantities measured and calculated by the data logger at the same instant of acquisition. For example, the
model HD35ED1NAB measures four quantities and calculates five quantities (the derived humidity quantities) and one sample includes
one temperature measure, one CO measure, one CO
derived quantities).

The minimum logging interval may be smaller if the data logger only stores some of the available quantities.
