Low Flow Alarm
If the sampler detects a low flow situation, the red FAIL LED
will flash and the audible alarm will beep twice.
The sampler will continue in this mode for approximately 10
seconds. This gives you time to remove any blockage in the
line. If the condition does not change, the sampler will prompt
you for a block.

If the sampler detects the expected airflow it returns to
normal operation. If the sampler does not detect the
expected airflow it returns to the low flow alarm state until the
airflow recovers.
