4. 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.
5. Configure the unit via the touchscreen interface to sample for 5
minutes and set a 10 second hold.
6. Set Cycles to 10 so the instrument will take 10 five-minute
samples.
7. If an average of more than one count per five minute sample is
reported, reset the instrument to sample for 30 minutes again to
purge it, then repeat the Purge Test again.
8. After the instrument has met the requirement of the Purge test,
return the instrument to its normal location and operating status.
9. If the instrument still fails the Purge Test, contact Lighthouse
Tech Support for assistance at 800-945-5905 (USA Toll Free),
541-770-5905 (Outside of USA).
