within the storage interval are
displayed

The average values of the exposures based on a shift of e.g. 8 hours (TWA) of all
the active sensors for the exposure evaluation are displayed

The short-term values (STEL) = average values of the concentrations over the
average value duration of all the active sensors for the exposure evaluation are
displayed
