Purge Count
Test
This section will provide you with the procedure to check the counter

six (6) five (5) minute samples must be taken. There should be no more
than 1 count on average per five-minute sample.
1. Disconnect power from the instrument.
2. Connect the Purge filter to the sample inlet.
3. Apply power to the instrument.
4. Configure the unit to run one 30-minute sample.
5. Run the 30-minute sample. This time allows the unit to warm up
and purge any residual particles that might be inside the
instrument.
6. Stop sampling.
