CHECK THE OXYGEN CONCENTRATION MONITOR FUNCTION
1. Place a calibrated oxygen concentration analyzer in the middle of the bassinet.
2. Connect the oxygen input system, waitting until the oxygen concentration steady, between
the value displays in the oxygen concentration indicator and the oxygen concentration analyzer
displays should in the range of ±3%.
CHECK THE FUNCTION OF OXYGEN CONCENTRATION DEVIATION ALARM
Connect the oxygen supply system with oxygen input connector and set the oxygen
concentration basic value at 30%. Waitting until the oxygen concentration display value reach the
basic value, then increase the oxygen flow rate rapidly. When the displayed oxygen concentration
value deviates the basic value to +5%, the incubator alarming, the “Alarm” light will flash with
continuous audible sound, and the Message indicator will show “High Oxygen”. Set the oxygen
concentration basic value at 30%. Waitting until the oxygen concentration display value reach the
basic value, then decrease the oxygen flow rate rapidly. When the displayed oxygen
concentration value deviates the basic value to -5%, the incubator alarming, the “Alarm” light will
flash with continuous audible sound, and the Message indicator will show “Low Oxygen”. When
