Dräger Isolette 8000 plus - Calibration and adjustment; Oxygen sensor calibration (option)

160 Instructions for use Isolette 8000 plus SW 5.n
Service
13 Reconnect the cables that were previously removed.
 Sensor module cable is connected to the shell.
 Scale cable and temperature probes cables are connected to the sensor
module.
14 Switch on the incubator at the controller on/off switch, while pressing the Audio
Paused/Reset key.
 System configuration mode appears.
15 Confirm that the Altitude field contains the correct height above sea level of the
site, to the nearest 1000 feet (300 meters). Consult a map or Google Earth if the
height above sea level is not known. Correct if necessary.
16 Note the oxygen calibration level.
 Oxygen calibration level is either 21% or 100%.
17 If the oxygen calibration level is 100%, the 100% calibration fixture (with hose
barb) must be installed below the sensor module. If the oxygen Calibration Level
is 21%, the slide lock fixture (without hose barb) must be installed below the
sensor module.
18 Switch off the incubator at the controller on/off switch, wait 1 minute, and turn
the incubator back on in normal mode.
19 When 30 minutes have elapsed since step 1 (exposing the oxygen sensors to
air), begin oxygen calibration (see Oxygen sensor calibration (option) on page
160). Note carefully the use of room air (21% oxygen) or pure oxygen, as
dictated by the presence or absence of the 100% oxygen calibration fixture on
the hood.
20 Perform the functional check procedure (see page 63).
13.6 Repair
Dräger recommends that all repairs are performed by DrägerService and that only
authentic Dräger repair parts are used.
13.7 Calibration and adjustment
13.7.1 Oxygen sensor calibration (option)
WARNING
Risk of death or serious injury
Calibration of the oxygen sensor must be done at least every 7 days. Calibration
may need to be done more frequently if barometric pressure changes occur and/or
highest level of system accuracy is required by the clinician for patient treatment.
► If the message Cal Required is displayed, calibrate the servo oxygen control
system.
If the sensor module cable is disconnected from the shell connector during
operation, the message Cal Required is displayed. This message indicates that
the servo oxygen control system must be calibrated.
