Fault Isolation
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 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. Call your
Lighthouse Service Representative for assistance.
