SAD self-test
The first test verifies whether the sensor detects an air signal. The second test
performs a comparison between the voltage threshold and the calibration value.
This test is performed every 1.5 s (=time required by an air bubble at maximum
blood flow to reach the venous cannula) during priming and rinsing as well as
during the therapy and reinfusion phases.
