5. Allow the instrument to sample through a 30-minute period. This
time allows the unit to warm up and purge any residual particles
that might be inside it.
6. Configure the unit to sample for 5 minutes with a 10-second hold.
7. Set Cycles to 6 so the instrument will take 6 samples.
8. If more than one count per five-minute period is reported, allow
the instrument to sample for 30 minutes to purge it, then repeat
the test.
9. After the instrument has met the requirement of the Purge Count
test, return the instrument to its normal location and operating
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 at 800-945-5905 (USA Toll
Free), 541-770-5905 (Outside of USA).
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
for assistance at 800-945-5905 (USA Toll Free), 541-770-5905
