4/Tests and Troubleshooting

Remarks: If the bleed resistor calibration test fails, check altitude and drive gas
settings. Ensure that the breathing circuit gas is exhausting out the scavenging
port during the test. A negative finding indicates a massive circuit leak. Check for
proper regulator pressure calibration. Ensure that the Flow Valve Cal test was con-
ducted properly. Otherwise, failure indicates a calibration problem with the flow
valve.
