5.1.3 Automatic preparation for use
Dräger recommends checking the software settings
before starting work with the test unit.
When a test is launched using the test software, the test
unit is switched on automatically for usage:
– When the software is started, all sensors are zeroed.
Except for the high-pressure inlet, the connections
must be depressurised at this point.
– The artificial lung is positioned.
When the test unit is connected to the PC and
supplied with power, the status LED lights up. The
different meanings of the colours of the status LED are
explained on the help pages (F1).
