3.3 INSTALLING ASTRAPRO
TM
SPIROMETRY SOFTWARE FOR PC
For USB compatible spirometers, a driver must be installed on the
computer. These instructions are for use with PC and software only.
Not needed for direct print.
3.2 EXPORTING TESTS TO OTHER
SYSTEMS
The Astra 300 spirometer can export the tests saved
previously in the Internal Database to other
management systems at other locations.
The equipment shows the information in comma-
delimited mode, making it compatible with many
different systems.
The information is available in the following files:
TESTS.TXT Contains the database tests
GRAPHICS.TXT Contains the graphs in Flow/Time mode
The graph file, as indicated, contains the graphs for
each test in Flow/Time mode. If you want to display
the graphs in Volume/Time or Flow/Volume mode in
the new management system, the following must be taken
into account:
The flow signal with the turbine-type transducer is
sampled at 50Hz.
The ratio of the axes in the Volume/Time graph must be
adjusted to 1 liter = 2 seconds.
The ratio of the axes in the Flow/Volume graph must be
adjusted to 2 l/s = 1 l

Support, who will provide any further information you
may require.
