Calibrating O
sensors
2
Savina uses one O
sensor for O
2
(sensor 1) and a second, separate O
(sensor 2).
The O
sensor for O
control and display (sensor 1)

is automatically calibrated by Savina:
— when the apparatus is switched on
— after 8 hours' operation
— when the O
sensor is replaced
2
— if sensor 1 and sensor 2 differ from each other by more
than 2% by volume
— when the air pressure changes by more than 200 hPa,
e.g. during transfer flights by helicopter
— when the temperature changes by more than 10
During automatic calibration, the following message appears in
the information line on the screen:
O
calibration active

After calibration is complete, the following message appears:
O
calibration ok

The O
sensor for O
monitoring (sensor 2) has to be

calibrated manually:
— once per month,
— if the following alarms occur:
!!! FiO
