This menu enables the user to simulate various Flow Tests through the system. The menu also shows the
current status of the Mass Flow Controller. Note that the items displayed in this menu change with the system
analysis type. For instance, The TIC Exhaust and Sample Out Test/Flow are only displayed in TC - TIC
systems. Any settings made by the user in this menu are automatically reset when the user exits this menu.
1. Exhaust Test. Use this function to simulate the flow through the Exhaust Valve. When the Exhaust Test
is activated, an "*" will be shown, and a small menu will display the following data:
Time:
MFC Setpoint:
MFC Flow:
Status:
2. Exhaust Flow. This is similar to the Exhaust Test menu, but its time has been extended to 999s, allowing
the user to locate any blockage in the system. Pass, Warning and Fail are automatically shown on the
screen, depending on the status of the test.
3. Sample Out Test. This is similar to the Exhaust Test, but for the Sample Out Valve.
4. Sample Out Flow. This is similar to the Exhaust Flow, but for the Sample Out Valve.

The time for the flow test is 30 seconds. This time shows the time left to the end of
the test.
This is the BioTector mass flow controller setting for the flow test.
This is the actual flow from the mass flow controller. If there is no blockage in the
lines, then the setpoint should match the flow.
At the end of the test, the status below is shown:
TESTING: Test in progress.
PASS: The Exhaust Test finished its cycle with a flow above the Pass (Flow
Warning) level.
WARNING: The Exhaust Test finished its cycle with a flow below the Pass level,
but above the Fail (Low O2 Flow) fault level.
FAIL: The Exhaust Test finished its cycle with a flow below the Fail (Low
O2 Flow) fault level.
