During operation, the switching valve (oxygen compensation) V4 is set to
"measurement" – that is, the connection between the inspiratory side and the
oxygen sensor is open. During oxygen sensor calibration oxygen passes to
the oxygen sensor. This layout permits "online" calibration of the oxygen sen-
sor S3.1 during ventilation. The oxygen sensor S3.2 must be calibrated man-
ually (patient disconnected).

The device has an oxygen sensor detector which is necessary for the „LPO"
option.
