Humidity Check - GE Giraffe Service Manual

nOTE: If the unit has been used in the last 2 hours, the patient history query appears.
6. Adjust the set temperature to silence the prompt tone.
7. Check the patient probe. If the probe is below 30 C, the display will show -L-. Warm it by placing it between
your fingers, and verify that the baby temperature reading increases.
8. Unplug the patient probe and check that both visual and audio alarms trigger in the Baby control mode.
9. If so equipped, check the operation of the bed elevating system. Raise and lower the bed along its entire
travel range, checking that the mechanism operates smoothly. Check that the pedals on both sides of the
unit raise and lower the bed.
10. Check the power failure alarm and the battery backed up memory. Make note of the current control mode
and temperature settings and wait one minute, then unplug the Incubator from the wall outlet. An alarm
should sound and the power failure indicator should light. Wait one to two minutes and plug the Incubator
back in. Verify that the alarm cancels and that the Incubator returns to the same control mode and
temperature settings it displayed before the power interruption.
nOTE: A fully charged battery should supply the power failure alarm for 10 minutes minimum (IEC 60601-
2-19 clause 101.3). If the alarm is tested for the full 10 minutes, the Incubator must be run at least two
hours to recharge the battery before it is used with a patient. Total recharge time is 10 hours. The battery
charges only when the unit is powered on.
11. Perform the Leakage Current and Ground Resistance checks in sections 3.8 and 3.9.

2.3 Humidity Check

Turn on the Giraffe unit and verify that the Servo Humidity icon is on the screen. Set the Humidity to 65%. Wait
for 4 minutes. If no alarms are seen (except for a possible "Add Water" message) the humidifier is operational.
nOTE: It is not necessary to have water in the reservoir to perform this test.
