Purge Count Test
This section provides the user with a procedure to check the counter for
zero counts. A purge filter must be attached to the instrument and
fifteen (15) five (5) minute samples must be taken. There should be no
more than 1 count on average per five-minute sample.
1. Connect the Purge filter to the sample inlet.
2. Connecting Purge filter
3. Apply power to the instrument.
4. Configure the unit to sample for 30 minutes.
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 fails the Purge Count test, perform the following
steps:
1. Check the data over the last 6 five-minute sample times. 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.
2. 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 (Toll Free USA) or 541-770-5905 (Outside of
USA) for assistance.
3. Use only 250V 2A Slow-blow fuses to replace blown fuses. If
replacements blow within a few minutes, contact a Lighthouse
Service Representative and remove the instrument from service.
Spares are shipped with the instrument.
