warning is displayed).
Or:

and save all readings on the testo 400
(see Section 9.6).
If large differences in flow velocities are ascertained over the cross-
section, the number of measuring points must be increased. The
number of measuring points is then adequate if the measurement value
for each area is representative for its immediate surroundings, i.e. if it
can be regarded as a genuine mean value for its portion of the area.
