Sensor Inspection
Air Flow Sensor:
1) - Disconnect the supply gases from the device.
- Check if the reading of the “Air Flow”
is a stable value in correspondence with that indicated
in Table 1.
2) - Connect the supply gases to the device.
- Select the “AirVal”.
- Open it progressively with “selection
” . When the air starts to flow through the in
spiratory
outlet, the reading of the air flow begins to increase until the opening value of the valve reaches
the maximum value (maximum flow). Check the maximum value reached in the air flow reading;
it is usually greater than 800 units.
3) - Close valves with "Reset
" Key.
Oxygen Flow Sensor:
1) - Disconnect the supply gases from the device.
- Check if the reading of the “Oxi Flow”
(Line 2) is a stable value in correspondence with that
indicated in Table 1.
2) - Connect the supply gases to the device.
- Select the “OxyVal”.
- Open it progressively with “selection
” .
When the air starts to flow through the inspiratory
outlet, the reading of the oxygen flow begins to increase until the opening value of the valve
reaches the maximum value
(maximum flow). Check the maximum value reached in the oxygen
flow reading; it is usually greater than 800 units.
3) - Close valves with "Reset
" key.
