The ParticleScan
®
Lite
Operating Instructions
1. How to charge the ParticleScan Lite
a.
To charge the ParticleScan Lite, connect the AC adapter to the input socket located on the side of the device.
(
Caution:
only use the supplied AC adapter. Other AC adapters may damage the ParticleScan Lite.)
b.
Fully charged, the ParticleScan Lite should provide approximately 4 hours of continuous operation.
c.
When the battery power level becomes low, the green ‘Low Battery’ indicator will flash. It takes approximately
4 hours to fully charge the ParticleScan Lite.
2. How to take airborne particle measurements
a.
Take the ParticleScan Lite out of the carrying case and remove the protective red rubber cap from the air
intake nozzle located at the top of the ParticleScan Lite. (Note: do not operate the ParticleScan Lite with
the cap in place as this may damage the internal pump.)
b.
Connect the supplied isokinetic probe to the air intake nozzle with the attached plastic tube. The ParticleScan
Lite is now ready for sampling.
c.
Turn ParticleScan Lite on with the ON/OFF switch located on the right side of the device. A humming sound
indicates that the pump is drawing in air for sampling.
d.
Immediately after it is switched on, the instrument starts a short countdown until its first particle reading.
The particle reading is updated every 2 seconds thereafter.
e.
The particle reading appearing in the display represents the concentration of particles (0.3 µm or larger) per
cubic foot of air.
f.
To switch the ParticleScan Lite off, set the ON/OFF switch to the ‘off’ position. (
Note:
for storage and
transport, the protective red rubber cap must always be placed over the air intake nozzle.)
3. Testing and cleaning the sensor
a.
After repeated readings in dusty or polluted environments, the particle sensor may accumulate contaminants.
As a result, the particle reading may become inaccurate.
b.
To test the sensor, a purge filter is supplied with the ParticleScan Lite. Simply connect the plastic tube from
the purge filter to the air intake nozzle and switch the ParticleScan Lite on.
i.
If the particle reading reaches zero after a few readings, the sensor is clean.
ii.
If the particle reading does not reach zero within a few minutes, this may be an indication of sensor
contamination. In such a case, leave the ParticleScan Lite running for several hours with the
purge filter attached. Should the readout then still not show a zero count, the ParticleScan Lite
should be returned for cleaning and recalibration.
c.
Two basic steps can be taken to reduce the accumulation of contaminants on the sensor:
i.
Measurements in very polluted environments should be avoided.
ii.
The purge filter ‘zero count’ test should be performed regularly after a few hours of use.
4. Calibration and Service
The ParticleScan should be calibrated once per year to ensure continuous, accurate and reliable performance.
Contact the Technical Support at 1-888-560-1020 to have your ParticleScan recalibrated.
