TABLE OF DEFINITIONS AND SYMBOLS

TECHNICAL DEFINITIONS

SKIN TEMPERATURE SENSOR: A sensing device including the link with the equipment intended to

measure the infant’s skin temperature.

INCUBATOR TEMPERATURE: Air temperature at a point 10cm above and centered over the mattress

surface.

CONTROL TEMPERATURE: The temperature set at the temperature control.

AVERAGE INCUBATOR TEMPERATURE: The average of the maximum and minimum Incubator

temperatures achieved during Temperature Condition.

STEADY TEMPERATURE CONDITION: A condition which is reached when the temperature does not

vary by more than 1℃over a period of 1 hour.

TEMPERATURE ALARM CHECKOUT STATE: The difference between real temperature and control

temperature is within ±0.5℃and such state lasts for over 10 minutes. The equipment must stay in such

state when check up the alarm about temperature

TEMPERATURE UNIFORMITY: The amount by which the average temperature at each of four points

10cm above the mattress surface differs from the Average incubator Temperature at steady

Temperature Condition. The four points are the centers of four quadrants formed by lines that divide the

width and length of the mattress surface.

SERVICEMANUALFORINFANTINCUBATOR EDITION/REVISION B/0
