Purging the Particle Counter Sensor

WCaution
To avoid possible damage to the Particle
Counter, avoid using the Particle Counter in
an excessively dirty or dusty atmosphere.
Excessive particle intake can damage the
Particle Counter.
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 µm in five minutes or not more than one
particle per 0.5 cubic foot should be apparent. This
purges the Particle Counter.
Once the unit is purged, resume normal use. Remove the
Zero Count Filter and adapter from the Isokinetic Probe.
