unit will be in “Standby mode” mode
Note: If the unit is being used only
with air, the unit will display “--”. The
Oxygen control is locked to 21%. If
the user tries to select a percentage
of Oxygen greater than 21% the
message "O2 Calib Error" is
displayed.
7.2 Oxygen calibration routine description
The SLE1000 oxygen calibration routine is as follows:
The first 180 seconds after power up the unit calibrates the
system using air. The unit displays the text “CAL” in upper case
characters.
The second 90 seconds the unit calibrates the system using
100% oxygen. The unit displays the text “cal” in lower case
characters.
Note: The user can when the unit is displaying “cal” in lower case letters set
the oxygen percentage.
The following 30 seconds the unit displays “--” as the unit allows
the oxygen monitoring system to stabilize.
Note: If the unit is being used with air only the “--” will not be replaced by
the measured value of percentage of oxygen. In standby mode the “O2
Calib Error alarm” will not trigger. The user will not be alerted to the
calibration failure until either CPAP or Flow mode is selected. The user will
then cancel the alarm accepting air only use.
