The testo 440 has permanently installed application menus. These enable the
user to carry out convenient configuration and implementation of specific
measuring tasks.
Available application menus are enabled as soon as a probe is
connected. Unavailable application menus are greyed out on the
display. More than one probe has to be connected to make some
application menus accessible.
The units for the measuring values depend on the ISO/US setting and
configuration in the Basic View.
