calibration
Offset calibration
The O2 flow calibration is divided into two parts
•
The offset calibration
•
The gain calibration
The Offset calibration is performed with the use of the service mode only. The gain
calibration is performed by using an external flow measurement device.
To calibrate the O2 flow sensor follow this preparation sequence:
1.
Ensure that the system is turned OFF and line power is disconnected.
2.
Open main engine according to section 7.2.4.
3.
Remove internal back-up battery according to section 7.9.1.
4.
Re-insert exp. valve assembly.
5.
Connect line power and gas supply and turn ON the system.
6.
Verify that the system
performs the power-up test.
7.
Start the service mode
according to section 4.3.
8.
Use a 10” 22 mm tube to
connect the external flow measurement device to the inspiratory
connection.
9.
Verify that the direction of flow is correct for the measurement device.
10.
Turn on the flow measurement device and let it warm up according to
manufacturers instructions.
11.
Select O2 for the measured gas on
the flow measurement device.
12.
Select the “O2” and “x 1” button.
13.
Verify the flow to be 0 L/Min on the
external flow measurement device.
14.
Check the “O2 flow” “Actual” to be
at the “Rated” value
±
50 digits.
15.
If not, readjust the “Zero” for the O2
flow sensor with R 306 on the main
board B to read the “Rated” value
±
10 digits.
