OPERATOR’S MANUAL FOR INFANT INCUBATOR EDITION/REVISION B/1
When the Air Mode works stablly, change it into the Baby Mode, set temperature at 37 . ℃
Keep the temperature detected by skin temperature sensor is 2 lower than the set temperature ℃
while making the displayed air temperature 4 lower than the set skin temperature. The sensor ℃
failure alarm should be actived then.The “Alarm” light will flash with continuous audible sound,
and the Message indicator will show “Skin Sensor 1 Position”.
Pull off the skin temperature sensor1, the sensor failure alarm should active. The “Alarm”
light will flash with continuous audible sound, and the Message indicator will show “Skin Sensor
1”.
F. CHECK PRECISION OF SKIN TEMPERATURE SENSOR
Put the skin temperature sensor with the mercury thermograph for the accuracy with ±0.1ºC
into the water cup with the temperature as 30ºC±5ºC. Make the probe of the skin temperature
sensor and the mercury ball as closely as possible and stir enough, then read the value of
mercury thermograph. Compare the value of the skin temperature sensor and the mercury
thermograph, and the deviation must be within 0.5ºC.
NOTE: Please check again if the accuracy of the skin temperature sensor exceeds the
permissibility deviation. Please let the professional maintenance man service
machine if the accuracy the skin temperature sensor exceeds the permissibility of
deviation again.
G. CHECK THE SENSOR BOX
Check the connection between the modular and its socket. Only when the interface of the
sensor box is correctly facing the interface of the sensor socket, they can be successfully
connected.
STATOR
Undraw the left stator of sensor box as the arrow indicates; under the condition of stator
undrawing, undraw the sensor box outwards, to check if the Sensor box slides in or out of the
hood smoothly. When the modular falls off from the hood, The “Alarm” light will flash with
continuous audible sound, and the Message indicator will show “Box Position”. After the
modular being put into the correct location and being fixed by stator, the alarm cancels
automaticly as well as the sensor connect indicating light off.
