To avoid possible damage to the meter, avoid using the meter in an
excessively dirty or dusty atmosphere.
Excessive particle intake can damage the meter.
To purge the particle counter sensor:
1. Fit the adapter onto the end of the zero count filter.
Note the arrow on the filter denoting airflow direction.
2. Connect the adapter directly onto the end of the isokinetic probe.
3. Operate the unit for approximately 15 minutes.
4. On the average, not more than one particle greater than 0.3
µ
m in five minutes
or not more than one particle per 0.5 cubic foot should be apparent.
Once the unit is purged, resume normal use. Remove the zero count filter and
adapter from the isokinetic prob.
