The Bleed Resistor instructions appear when the focus is on the Bleed
Resistor menu item.
Refer to Section 5.4.5, "Bleed Resistor Cal."
Read all steps before you start:
1. Complete the Insp Flow Valve calibration.
2. Put #2 plugs in the manifold and the drive gas ports of the vent engine.
3. Push the ComWheel to show the next menu.
4. Select Start.
The calibration fails if the flow required to reach 91 cmH2O is > 16 l/min.
• If the outcome of the calibration is Pass, the new calibration data is saved.
• If the outcome is Fail, the old calibration data is retained.
• The result of the calibration is saved to the Event Log.
Selecting Previous Menu before the calibration is done aborts the calibration
in progress and keep the old calibration constants.
Menu Item Message text
Start Calibrate manifold pressure to
bleed resistor flow.
Blocked text:
"Connect a supply of the drive
gas to continue."
Bleed Resistor Data Show bleed resistor calibration
table.
Previous Menu Return to the previous menu.
During Calibration:
"Calibration in progress. Push
ComWheel to cancel."
The Bleed Resistor Data menu contains a table of 17 entries from a previous
calibration. The table is erased at the start of the calibration. The table is
updated in real time during the calibration.
Comments
Blocked if the
ventilator drive gas
supply pressure would
cause a gas supply
