Adjustments and calibrations
3.4.1
Invasive pressure calibration
Perform pressure calibration whenever the pressure transducer (probe) is replaced with different
type of transducer.
1.
Enter P/PT service menu:
Monitor Setup -
Install/Service - Service - Parameters
2.
Enter Calibrations menu.
3.
Connect a pressure transducer with a pressure manometer to the P3 connector. Select
Calibrate P3. Leave the transducer to room air pressure.
4.
Press the ComWheel to start zeroing.
5.
Supply a pressure of 100 mmHg...300 mmHg to the transducer. The recommended pressure
is 200 mmHg.
6.
Set the pressure on the display to match the pressure reading on manometer and press the
ComWheel. A tolerance of
±
1 mmHg is allowed.
7.
The text 'calibrated' will appear on the display.
3.4.2
Temperature calibration
NOTE: For the temperature calibration, separate test plugs (25 °C and 45 °C) are necessary. A test
set of two plugs is available from Datex-Ohmeda, order code 884515.
Performe temperature calibration whenever the measured values deviate more than
±
0.1.
1.
Enter P/PT service menu (Monitor Setup, Install/Service, Service, Parameters).
2.
Enter Calibrations menu.
3.
Press the protect button at the bottom of the module and select OFF protect mode. Release
the button.
4.
Select Calibrate T3/Calibrate T4.
