Check the following points every three months or so.
Item to check Procedure Description
Incubator Air
Temperature
Control
Set the temperature to 36.0
℃
in manual
control.
The displayed incubator air
temperature should be stable at
36.0±1
℃
.
Skin
Temperature
Control
Place the skin temperature probe at about
10cm above the center of the mattress surface
in the incubator and set the temperature to
36.0
℃
in servo control.
The displayed skin temperature
should be stable at 36.0±0.5
℃
.
Humidity Control
Set RH to 90% with the incubator air
