In the servo control mode, the heater output is controlled by giving priority to the maintenance of the infant’s
skin temperature. It detects the infant’s skin temperature with a skin temperature probe attached to the infant’s
abdomen and maintains the optimum thermal environment through feedback control. In the servo control
mode, the heater output is controlled automatically to maintain the infant’s skin temperature at a constant level
(i.e. the set temperature); if the infant’s skin temperature is lower than the set temperature, the heater output
will increase, while if the infant’s skin temperature is higher than the set temperature, the heater output will
decrease. After attaching the skin temperature probe to the infant, check that the infant’s skin temperature
displayed on the skin temperature display is stable.
Servo control operation is recommended unless the operator particularly needs to select the manual control
mode.
In the manual control mode, the operator must consider the effects of environmental changes around the
unit (direct sunlight, heat energy provided by the phototherapy unit, etc.) to control the heater output. In the
servo control mode, on the other hand, the heater output is automatically controlled to maintain the infant’s
skin temperature at a level preselected by the operator and is corrected automatically to some extent for such
environmental effects.
Insert the plug of the skin temperature probe (yel-(1)
low) cable firmly into the skin temperature probe
connecting port 1.
(2) Attach the skin temperature probe to the infant.
After the temperature reading has stabilized, press
and hold
for one second.
(3) When the “°C” indicator on the right of the setting
display comes on and the set skin temperature on
the setting display and begin to flash, press
or to set the skin temperature to a desired
level. The skin temperature can be set in the range
of 34~38°C in 0.1°C increments.
The set skin temperature on the setting display (4)
and
will stop flashing and remain on, and the
skin temperature will be set to the displayed level
and the heat control mode will be set to
. The
heater output will be controlled to maintain the skin
temperature at the set level.
