Tests
–Gas mixer:
– With electronically controlled gas mixer:
The flow control valve of the O
2 flowmeter is closed.
– With mechanically controlled gas mixer:
All flow control valves are closed.
Quick tightness check
1. Touch the Tests... button.
2. Touch the System test button.
The checklist opens and the breathing system pressure is displayed as a bar
graph in the lower left-hand corner.
3. Press the O
2+ key and keep it pressed until the displayed breathing system
pressure no longer rises.
4. Release the O
2+ key.
5. Wait until the pressure stabilizes between 15 and 30 hPa.
– When the pressure has stabilized, continue with the check, see step 6.
– If the pressure continues to fall, there is a leakage present. Decide whether
to end the check or continue with it.
6. Set the vaporizer to the smallest delivery setting. To do this, turn the control dial
from the 0 position to the first mark on the scale.
7. Observe the breathing system pressure. The pressure must remain stable and
may only drop at a minimally slow rate.
If the pressure drops faster, the vaporizer is leaking.
8. Close the vaporizer. To do this, set the control dial to the 0 position.
9. Exit the System test again. To do this, touch the Cancel button.
For leaky vaporizers, the compete leakage test can be used to determine how large
the leakage is.
Complete leakage test
Testing the vaporizer in the closed state:
1. Touch the Tests... button.
2. Touch the Leakage test button.
3. Perform the leakage test with the vaporizer closed.
If no leakage value is displayed, the test has passed. If the determined leakage
is at least 500 mL, the leakage value Leakage (total) is displayed.
Testing the vaporizer in the open state:
1. Touch the Tests... button.
2. Touch the Leakage test button.
3. Set the vaporizer to the smallest delivery setting. To do this, turn the control dial
from the 0 position to the first mark on the scale.
4. Perform the leakage test with the vaporizer opened.
If no leakage value is displayed, the test has passed. If the determined leakage
is at least 500 mL, the leakage value Leakage (total) is displayed.
5. Close the vaporizer. To do this, set the control dial to the 0 position.
