SECTION 9: CALIBRATION PROCEDURES
Part No. 715-0080, Rev. B
- 73 -
3.
Turn the power button on and observe for a couple of seconds; all LEDs should be illuminated,
all seven-segmented LED elements turned on, and the audible alarm on. The
BAT CHG
and
AC OP
indicators should stay on.
4.
Remove the sensor simulator.
SENS FAIL
and
SYS FAIL
alarms should activate. Reconnect
the sensor simulator to
J2
on the control board.
5.
Set the thermostat switch on the sensor simulator to OPEN (up position). The
AIR FLO
indicator should be on and alarm should sound continuously. Set the thermostat switch to
CLOSED (down position).
6.
Turn the incubator power off. Remove the fan impeller from underneath the mattress tray, turn
the unit on, adjust the temperature setpoint to 37.0
C, and verify that the
AIR FLO
alarm
activates under twelve minutes. The
AIR FLO
alarm may sound for a few minutes. Replace
the fan impeller.
7.
With the incubator turned on, disconnect the power cord. An audible alarm indicating loss of
AC power should sound, which can be silenced by pressing the
MUTE
button. Turn the
incubator power off and disconnect the negative battery cable. Set the external power supply to
12 volts and connect the external power supply output to the battery cables, observing proper
polarity.
8.
Turn the incubator power on. Connect the digital multimeter leads to the battery cables. Slowly
reduce the supply voltage. The
LOW BAT
warning LED should illuminate at 10.8
0.3 volts
and the audible alarm should sound at approximately 8 second intervals. The
PWR FAIL
indicator should turn on at 10.1
0.1 volts and the incubator power should turn off. The audible
alarm should sound continuously. If these alarms turn on at incorrect voltages, see the Control
Board Calibration procedure.
9.
Turn the incubator power off and disconnect the external supply. Reconnect the negative
battery cable to the battery. Connect one end of the red clip lead to
TP7
of the control board
and run the other end outside the incubator. Similarly, connect one black clip lead to
TP1
and
one black clip lead to
TP2
of display board. Disconnect the sensor simulator from
J2
on the
control board and connect the airflow tray cable to
J2
on the control board. Connect heater and
ground wires also. Install the inner and outer infant chambers.
10.
Using the calibrated temperature measuring device, monitor the temperature in the center of the
chamber 10 cm above the center of the mattress.
