the instrument to sample for 30 minutes to purge it, then repeat
the test.

status.
Troubleshooting
If the instrument does not pass the Purge Count test, please perform the
following procedure:
1. Check the data over the last 6 five-minute sample times.
2. If sporadic counts over all or several channels are occurring, the
unit may still have particles inside it. Allow the unit to sample
overnight with the purge filter attached before retesting it. If the
counts are still high after the overnight purge, call Lighthouse
Technical Support for assistance.
3. If the data shows consistent counts in the smallest channel only,
the instrument may have electrical problems and may need to be
returned to Lighthouse. Call a Lighthouse Service Representative
at 800-945-5905 (USA Toll Free) or 541-770-5905 (Outside of
USA) for assistance.
