Chapter 1 – About Particle Counting
1.1 How Do Particle Counters Work?
Laser particle counters use a laser diode light source and collection optics for particle detection. Particles scatter the light
from the laser diode beam in the direction of the collection optics. The collection optics focus the light onto a photo
diode that converts the bursts of light into electrical impulses. The pulse height is proportional to the particle size.
Impulses are counted and their intensity is measured for particle sizing. The results are then displayed digitally for the
specific size channel(s) and set measurement unit.
1.2 The Two ParticleScan Models
The six-channel ParticleScan handheld particle counters are available in two configurations:
ParticleScan Pro
This model is designed for indoor air quality use, featuring a 0.025 cfm sampling rate.
The flow rate of 0.025 cfm of the ParticleScan Pro is more suitable for environments with normal to high particle
counts since the lower flow rate and smaller sampling diameter allow more accurate counting of elevated
particle concentrations.
ParticleScan CR
This model is designed for cleanroom use, featuring a 0.1 cfm sampling rate and a EPA filter for the exhaust air.
The higher flow rate of the ParticleScan CR permits statistically significant results even if the particle
concentration is low and the measurement time is short.
1.3 Data ogging Options
ParticleScan Pro and ParticleScan CR handheld counters allow the logging (recording) of measurement data onto the
ParticleScan’s internal memory from where it can be downloaded at a later time to a computer via the ParticleScan Utility
Software or a web browser.
When the ParticleScan is connected to a computer or network, measurement data can also be logged in real time to the
computer via the ParticleScan USB Utility Software.
In both cases, the data can be viewed and saved to a text file that can be easily opened and formatted in any common
spreadsheet program. Logged data can also be printed directly from the logging window to a printer.
A printout of particle counting results can be used as a record whenever documentation of room cleanliness is required,
as in Fed-Std-209E cleanroom certification. A permanent record is also useful when tracking the particle concentration
trend at a workstation or other remote location.

3.2 ParticleScan Features
Isokinetic probe The isokinetic probe with the Tygon tube piece allows uniform low turbulence sampling of ambient air.
It is also necessary for proportional sampling of particles of all sizes.
Intake nozzle The intake nozzle is covered during shipping with a protective red plastic cap, which is designed to keep
small objects from entering into the sampling chamber. The cap must be removed prior to taking a sample to prevent
possible damage to the internal pump.
Display When the device is off and not connected to the charger, the display will also be off. If the device is off and
connected to the charger, it will show [charging] or [charged]. When the unit is sampling, the particle concentration
measured will be displayed. The displayed concentration can be shown for one particle size range at a time (see Particle
Size Indicators). When the Menu key is pressed, the display will show the user settings.
Particle Size Indicators The particle size indicators show which particle size range is currently displayed. When the Alarm
is set and the set particle concentration threshold is exceeded, the appropriate particle size indicator will flash and a beep
will sound.
Cumulative Count Ranges There are six cumulative size channels to select from: ≥0.3 / ≥0.5 / ≥0.7 / ≥1.0 / ≥2.0 / ≥5.0
microns. When a cumulative size channel is selected, the ParticleScan will count particles which are equal to and larger
than the selected size channel.
Differential Count Ranges There are five differential size channels to select from: 0.3–0.5 / 0.5–0.7 / 0.7–1.0 / 1.0–2.0 /
2.0–5.0 microns. When a differential size channel is selected, the ParticleScan will count the particles whose size lies
between the selected two size channels.
Data og Indicator This indicator lights up when data logging has been turned on. Whenever a measurement is taken, it
will be logged to the ParticleScan’s internal memory.
Timer On Indicator This indicator lights up when the auto timer is actively set. The Auto Timer is a feature that allows the
ParticleScan to take automatic measurements based on a timer schedule. The Auto Timer schedule is set via the
ParticleScan USB Utility Software or the web browser interface.

5.8 “Geiger Counter” Menu [GEIG]
The “Geiger Counter” function enables the ParticleScan to emit an audible signal at intervals which are proportionate to
the number of particles (≥0.3 µm) that are detected in a period of one second. The
“Geiger Counter” Menu allows the user to choose from 10 sensitivity levels. The most
sensitive setting is 1, which means that for each particle counted in a period of one
second, the ParticleScan will generate one beep. The least sensitive setting is 10,
which means that for every 500 particles counted in a one-second period, one beep
will be generated.
To change the “Geiger Counter” setting, press the Menu key until you reach the Menu
display starting with [GEIG]. Press and hold the ENTER key for two seconds until the

desired setting. Confirm your selection by pressing and holding the ENTER key for
two seconds until the selection stops flashing.
Note: Whereas the ParticleScan display updates particle concentration after 6 sec-
onds (default), the “Geiger Counter” issues a beep based on the number of particles sampled in one second. Due to the
shorter sampling period, the “Geiger Counter” reacts more quickly to changes in particle concentrations than the display.
12
5.6 Sample Time Menu [SAti]
The Sample Time Menu allows the user to select the sampling period (in terms of seconds) for particle sampling. The
default setting is 6 seconds, which means that the ParticleScan will sample and display a new particle concentration
measurement after 6 seconds.The minimum time period that can be set is 1 second and the maximum update period is
600 seconds (10 minutes).
To change the sample time period, press and hold the ENTER key for two seconds until the currently set time period

The Auto Timer Menu allows the user to activate or inactivate a timer program that has been set via the ParticleScan web
browser interface (see Chapter 7.7). The auto timer allows the ParticleScan to turn itself on and off to take measurements at
regular intervals. This is useful to collect regular particle samples over long periods, without having to sample all the time.
This is desirable for permanent sampling applications, in order to reduce the wear on the sampling pump and other com-
ponents. It also can be useful to reduce sampling noise in noise-sensitive environments.
Capter 5 – Adjusting Settings in t e Menu

5.13 IP Menu [IP]
The IP Menu allows the user to activate and deactivate the network port (RJ-45) and assign an IP address to the
ParticleScan on the network. The IP address is a number with which the ParticleScan is identified on a network. When the
IP number is entered into a web browser such as Internet Explorer, the ParticleScan can be accessed via the network.
The IP Menu has three main settings: IP OFF, D CP and STATIC. The default setting of the IP Menu is IP OFF, which means
that the RJ-45 port of the ParticleScan is inactive. NOTE: Data transfer via the USB port requires the IP Menu selection to
be set to [IP OFF]. To activate D CP, press the MENU key until the IP Menu [IP OFF] appears, press the ENTER key for three
seconds until [IP OFF] starts to flash. Then press the ARROW DOWN key once. [D CP] will appear flashing on the display. If
the ENTER key is pressed, the D CP mode is activated.
To view the current IP address that has been assigned to your ParticleScan by a network router, connect your ParticleScan
to a network with a network cable and ensure that D CP is selected in the IP Menu. The IP Menu should now show the IP
address assigned to your ParticleScan by intermittently displaying [DC P], [IP xxx’xxx’] and [‘xxx’xxx]. The x stands for
numbers. The IP address consists of four blocks separated by a period. The first two blocks have the “IP” in front. Blocks
three and four do not. A typical IP address could look like this on the ParticleScan display: [IP 192’168‘ 0’ 79]. In this exam-
ple, the IP address would be 192.168.0.79. It is this set of numbers together with the periods must be entered into the
address field of the web browser. When the IP address is flashing on the display, this means the ParticleScan is not receiv-
ing an IP address. This could be due to a problem with the physical connection to the network or a problem with the
D CP server. Note: If the ParticleScan was disconnected from the network, it can take up to 3 minutes for the ParticleScan
to be reassigned an IP address by the network router.
In some network environments, it may be desirable to manually assign a specific, fixed IP address, commonly referred to a
a static IP address. To set a static IP address, go to the IP menu, press the ENTER key for two seconds until the display starts
flashing. Then press the ARROW UP or DOWN key until [STATIC] flashes on the display. Press the ENTER key for two sec-
onds until a constant [-STATIC] appears. Now you can adjust the IP address [-IP Addr], the subnet mask [-Subnet] and the
gateway [-Gate], by pressing an ARROW key to reach the item to be modified, followed by pressing and holding the
ENTER key. The ARROW and ENTER keys serve to modify the IP address, subnet mask and the gateway.

C apter 6 – Maintenance of t e ParticleScan
Chapter 6 – Maintenance of the ParticleScan
6.1 The Battery
Your ParticleScan is equipped with a internal Ni-M (Nickel-Metal ydride) rechargeable battery pack. Fully charged, the
ParticleScan Pro will run continuously for up to five hours and the ParticleScan CR will run continuously for up to four
hours.
Note: For maximum battery life, IP OFF should be selected in the IP Menu (see Chapter 5.13).
6.1.1 ow Battery Indicator
When the battery is running low, both the Data Log Indicator and the Timer On Indicator will flash simultaneously. The
unit can operate for another 5-10 minutes from the moment the Low Battery Indicator comes on.
6.1.2 Recharging the Battery
To recharge the internal battery pack of the ParticleScan, simply connect the supplied power adaptor/charger to a power
outlet and the round connector to the power socket of the ParticleScan. It takes about 3 hours to fully recharge the inter-
nal battery pack. When the unit is turned off and the power adapter is connected, the display will show [charging]. When
the battery is fully charged, the display will show [charged].
Caution: Only use the supplied adaptor/charger to recharge the ParticleScan device.
There are two charging LEDs next to the power socket. The green LED is on when the power adapter is connected. The
red LED is on when charging is in progess.
6.1.3 Replacement of the Battery Pack
The ParticleScan features one of the most sophisticated charging circuits available today, which ensures maximum battery
life by monitoring voltage and temperature during charging. This means that the ParticleScan can be recharged over
1000 times before the battery pack may need replacement. To replace the battery, contact Technical Support, see page 28.
6.2 Sensor Testing & Cleaning
After taking repeated readings in non-controlled environments, the highly sensitive particle sensor in your ParticleScan
may have accumulated contaminants. As a result, the particle count may become inaccurate. A special purge filter is
supplied with the ParticleScan kit to test the sensor for contamination. The test should be undertaken as follows:
6.2.1 “Zero Count” Test
1. Remove the red protective cap or isokinetic probe from the ParticleScan’s intake nozzle.
2. Attach the tubing end of the purge filter to the intake nozzle.
3. Switch the ParticleScan on.
If the particle count reaches zero after a few readings, the sensor is clean.
If the particle count does not reach zero within a few minutes, this suggests sensor contamination. In such a case, follow
the below steps. (see Chapter 6.2.2)
6.2.2 Sensor Cleaning
To clean the sensor, the ParticleScan must be fitted with the purge filter and left running for several hours. Should the
readout still not show a zero count after that, the ParticleScan should be returned to a ParticleScan Service Center for pro-
fessional cleaning and re-calibration (see page 28).
Note: In order to prevent the gradual accumulation of contaminants on the sensor, the purge filter ‘zero count’ test
should be performed regularly, especially after having used the ParticleScan in environments with elevated levels of
airborne contamination.
5.14 Remote Monitoring Menu [InEt oFF] (Beta-Feature)
Please visit www.ParticleCam.com to find out more about this beta-feature. Important Note: Changing [InEt oFF] to
[InEt on] disables all normal functions. These normal functions can be enabled again at any time by selecting [InEt oFF].

ParticleScan with crossover adapter and net-
work cable for direct connection to the
ethernet port of a computer.
7.2 Computer Connectivity Options
There are three basic ways to connect a ParticleScan to a computer:
7.2.1 Via a Network
Connection: Network cable from ParticleScan Ethernet port to
network.
System requirements: Windows 98/ME/NT/2000/XP/Vista, Mac OSX,
Linux
Software requirements: Web browser, Java Runtime Environment
Other requirements: Network with router
If a network is available, connecting a ParticleScan to the network via a
network hub or switch allows to access the ParticleScan from any com-
puter in the network that has a web browser (e.g. Internet Explorer,
Safari etc.) and Java Runtime Environment installed. The ParticleScan CD
includes J2RE for PC. For other computers, the appropriate J2RE version
can be downloaded for free from www.java.com. On many current com-
puters Java Runtime Environment is pre-installed. The ParticleScan is
identified in the network by an IP address. The ParticleScan comes pre-
configured with its network port and IP address off. To activate the net-
work port and IP address of the ParticleScan go to the IP Menu and acti-
vate either D CP or STATIC (see Chapter 5.13).
7.2.2 Via a Crossover Connection
Connection: Network cable with crossover adapter from ParticleScan
Ethernet port (RJ-45) to computer Ethernet port (RJ-45)
System requirements: Windows 98/2000/NT/XP/Vista, Mac OSX, Linux
Software requirements: Web browser, Java Runtime Environment
Other requirements: Ethernet port (RJ-45) on computer, network cable
with crossover connector (supplied)
If no network is available, but the computer has an Ethernet port (RJ-45),
you can connect to the ParticleScan with the supplied network cable
and the crossover adapter. You connect to the ParticleScan via a normal
web browser by entering a valid IP address in the address window of the
web browser. It is recommended that a fixed (static) IP address is
assigned to the ParticleScan and the computer, otherwise IP addresses
are assigned randomly with each restart. An IP address can be assigned
to the ParticleScan in the IP Menu of the ParticleScan (see Chapter 5.13).

7.2.3 Via USB
System requirements: Windows XP/Vista
Software requirements: ParticleScan USB Connection Software and
ParticleScan USB drivers (supplied on CD)
Hardware: Computer with USB port, USB cable (supplied)
The USB connection of the ParticleScan is only supported for Windows
XP/Vista computers. For USB connectivity, the installation of ParticleScan
USB drivers and of the ParticleScan USB Connectivity Software is necessary.
These are included on the ParticleScan CD supplied with the ParticleScan.
Important: The IP Menu needs to be set to IP OFF] for the USB
connection to work (see Chapter 5.13).
7.2.4 USB Driver Installation
To allow data communication via a USB connection to a Windows com-
puter, two drivers need to be installed. This installation process is easy
and automatic.

Remote Monitoring Menu [InEt oFF] (Beta-Function)
The ParticleScan device features a beta-version of the new Remote Monitoring Menu (see Chapter 5.14). The
Remote Monitoring Menu allows the user to turn the ParticleScan into a remote particle monitor, which can
be accessed from anywhere around the globe via internet.
Please visit our Website
www.ParticleCam.com
to find out more about this beta-feature.
Important note: The selection of [InEt on] disables all normal ParticleScan functions. These normal functions
can be enabled again at any time by selecting [InEt oFF].
This is a free beta-version for trial purposes only. Full functionality is not guaranteed.

7.4 The ParticleScan Control Window
The ParticleScan control window which can be reached
via a web browser connection or a ParticleScan USB
software connection has numerous remote control and
data logging features.
7.4.1 Start/Stop Measurements
To manually start or stop a measurement, click on the
<Start> and <Stop> button. The measurement data is
displayed in six current measurement fields, after every
measurement update.
7.4.2 Sample Time
The <Sample Time> selection allows to select the
update period (in terms of seconds) for particle sam-
pling. If the setting is 6 seconds, the ParticleScan will
display a new particle concentration measurement
every 6 seconds. The time also coincides with the data
points logged.
7.4.3 Sample Repeat
The Once/Continuous selection allows the user to have
the ParticleScan take just one sample and hold the
result ([once]) or take continuous samples ([cont]) until
the sampling is stopped.
7.4.4 Measurement Units
Select one of the three measurement units: particles
per cubic meter (1000 L), particles per liter or particles
per cubic foot (cu.ft.). This can be done during or after
a measurement.
7.4.5 Count Type
Select between <Cumulative> and <Differential>. The
cumulative selection shows all the particles equal to
or larger than the selected size channel. The differential
selection shows the particles whose size lies between
two size channels. Refer to 3.2.
