Setting-Up

Supplying Power to the SidePak Aerosol Monitor

Attach the rechargeable battery pack to the SidePak™ Personal
Aerosol Monitor before use. This will “wake up” the battery from
storage mode. The battery can power the AM520 by itself or in
conjunction with the TSI AC adapter.

The SidePak

monitor also contains a miniature coin cell for powering

a Real-Time Clock. Changing the battery pack or disconnecting the
power supply/charger will not cause data to be lost. Flash memory
retains the data. The coin cell will last for many years. TSI will install a
new coin cell, if necessary, when the unit is returned for service. Th e
coin cell is not user-serviceable.

Installing the Lithium Ion Rechargeable Battery Pack

Battery packs slide on and off the AM520 in the direction shown
below:

Installing the Lithium Ion Battery Pack

1. Place the battery pack under
the AM520.

2. Push firmly to slide into place.

3. Fasten it in pl ace using the two
battery screws provided.

Setting-Up

7

Removing the Lithium Ion Battery Pack

1. To remove battery, remove
battery screws.

2. Firmly grip sides of
instrument and sides of
battery.

3. Pull apart.

AM520 Smart Battery Management System™
technology

The rechargeable Lithium Ion battery pack is designed with Smart
Battery Management System™ (SBMS) technology. It contains a gas
gauge/supervisor chip to monitor pack capacity and control
charging/discharging.

Chapter 2

8

The SBMS supervisor prevents the battery from overcharging when
the AC adapter has been left plugged into the battery. At end of the
charge cycle the SBMS supervisor disconnects (stops charging) the
cells while continuing to pass power on to the instrum ent. The SBMS
supervisor also prevents excessive discharge when the battery is
depleted.

TSI recommends fully charging the battery before first use of a new
instrument. The battery can be charged when not installed in the
instrument. Accordingly, a second battery can be charged on its own,
while the equipment is in use with another battery. TSI also
recommends recharging the battery after each use.

The SBMS system requires a few charge/discharge cycles to learn
the capacity of a new pack. (It should be close to capacity when you
first receive the battery.)

The SBMS system will learn the battery pack capacity more quickly if
the pack is fully charged and then fully discharged multiple times.

To maintain the greatest accuracy of the SBMS gas gauge, you
should periodically fully discharge then fully charge the battery (once
every few months).

Storing the Battery Pack between Uses

The rechargeable battery must not be allowed to sit in a fully
discharged state for long periods of time to prevent damage to the
instrument. The battery pack should be charged before storage and
recharged every six (6) months when not being used.

The rechargeable battery will last longer if it is stored in a cool place.
Hot temperatures over long periods of time (several months) will
increase cell internal self-discharge and eventually degrade the
battery capacity.

WARNING/AVERTISSEMENT

Remove LiOn battery during storage and transportation
of instrument.

Using the AC Adapter (power supply)

The AC adapter powers
the AM520 from an AC
wall outlet, and charges
the rechargeable battery
pack. The AC adapter
can run the instrument
and charge the battery at
the same time. The
battery will charge more
slowly when the
instrument is running.

Connect the AC adapter to an AC wall outlet and plug the other end
into the barrel jack on the side of the rechargeable battery.

Battery LED

When charging the battery, the green
LED in the battery pack will
repeatedly flash from dim to bright.
When the battery is fully charged, the
LED will stay on until the AC adapter
is unplugged.

If the temperature is too hot or too
cold to charge the battery, the LED
will flash 3 seconds on, then 1 second
off. If the battery has an internal fault
that prevents charging, the LED
flashes rapidly.

Battery Icon on Display

When the battery is charging, the battery icon on the AM520 display
repeatedly flashes a pattern with increasing numbers of segments.
When charging is complete, the icon indicates a full charge. A full
battery icon means at least 10 hours of battery life is available. When
battery life is less than 10 hours, the battery icon will show
proportionally less full.

When the battery life remaining is less than 15 minutes, the battery
icon will flash red. When the battery is depleted, the AM520 will
display a “LOW BATTERY” message for 5 seconds and then turn
itself off.

AM520 Displayed Battery Life

The AM520 shows battery life remaining in Hours:Minutes or Minutes
(user selectable ) when displaying the Survey mode menu or whil e
actively data logging and showing the Logging menu. Those scree ns
may first show battery life as asterisks (*) for a few seconds while the
instrument gathers power consumption data. If the AC adapter is
plugged in, "A/C Power" is displayed.

Installing TrakPro™ Data Analysis Software

TrakPro Data Analysis Software can preprogram the SidePak AM520
monitor, download data, view data, create graphs and statistical
reports, and combine graphs with data from other TSI instruments
that use TrakPro software. Refer to the TrakPro Data Analysis
Software manual for installation and operating instructions.

Prog 1 …Prog 5 activates a data logging test that has been

preprogrammed using TrakPro Data Analysis Software.
Preprogramming allows a great deal of flexibility that is not available
with manual logging, such as predefined start and stop times, logging
intervals, calibration factors, and more. See the TrakPro software
manual for more information.

To stop a test, press the ESC key. The AM520 will confirm to stop the
test or not, while data logging continues. If the ESC key is pressed,
data logging will continue with no break in the logged data.

If a test in progress is stopped, the AM520 will display the message
“Logging Stopped” and show whether any data was saved. If the test
is stopped before any data points have been record ed, the display will
show “no data saved”. This may happen if the logging interval is set
to one minute and the test is stopped before the first data point is
recorded.

Setting the Log Interval

The Log Interval is the time interval used
between recorded data points during Manual
Mode logging operations (log intervals for
Prog-1 through Prog-5 are set using TrakPro
Software). For example, if the Log Interval is
set to 30 seconds, a data point is stored to
memory once every 30 seconds. Longer Log
Intervals can be used to conserve memory
for long duration tests.

The SidePak AM520 always makes a measurement once every
second regardless of the log interval selected. Using a log interval
greater than one second results in stored data points that are
averages of the 1-second readings. For example, a 10-second log
interval will result in one stored data point every 10 seconds. Each of
those data points will represent the computed average of ten,
1-second readings.

Do not confuse log intervals with time Constant. Log intervals only
affect recorded readings. Time Constant only affects the AM520
OLED display.

Five log intervals choices are preprogrammed. This list of available
log intervals can be modified using TrakPro Software.

After selecting Log Interval from the Setup Menu, the display will
show LOG INTVLx where "x" is a number from 1 to 5. This is the
currently selected log interval. The value of that log interval is shown
on the second line.

Use the ▲ ▼ keys to scroll through the available log intervals. Press
↵ when the interval you wish to use is displayed. The factory-preset
choices are:

• Log Interval 1: 1 Sec.

• Log Interval 2: 1 Min.

• Log Interval 3: 5 Mins.

• Log Interval 4: 15 Mins.

• Log Interval 5: 30 Mins.

Chapter 3

22

Setting the Time Constant

The Time Constant is used to dampen
fluctuations in the displayed readings and
make them easier to read. The Time
Constant setting affects values shown on the
AM520 display only. Do not confuse Time
Constant with logging intervals. Time
Constant only affects the AM520 display. Log
intervals only affect recorded readings.

The SidePak AM520 always makes a measurement once every
second and updates the display every second regardless of the Time
Constant selected. Using a Time Constant greater than one second
results in displayed readings that are averages of the 1-second
readings. For example, a 10-second Time Constant will cause the
display to show an average of the most recent ten 1-second readings.
In other words it is a 10-second "moving average," updated every
second.

There are five preprogrammed choices for Time Constant. If
necessary, the list of available Time Constant may be permanently
altered using TrakPro Software.

After selecting TIME CONSTANT from the SETTINGS menu, the
display will show Time Constant x where "x" is a number from 1 to 5.
This is the currently active Time Constant. The value of that Time
Constant is shown on the second line.

Use the ▲ ▼ keys to scroll through the available Time Constants.
Press ↵ when the Time Constant you wish to use is displayed. The
factory-preset choices are:

• Time Constant 1: 1 sec

• Time Constant 2: 5 sec

• Time Constant 3: 10 sec

• Time Constant 4: 15 sec

• Time Constant 5: 30 sec

Operation

23

Log Interval vs. Time Constant

• The Log Interval is the time interval used between recorded
data points. It can be set using the SETTINGS menu and in
Program logging mode using TrakPro software.

• The AM520 always takes a measurement once every second
regardless of the Log Interval. Using a Log Interval greater than
one second results in stored data points that are averages of
the 1-second readings. For example, a 10-second log interval
will result in one stored data point every 10 seconds, with each
data point being the average of ten 1-second readings. Using a
longer logging interval conserves memory in the instrument
during long sample runs.

• The Time Constant is an averaging period used to dampen
fluctuations in displayed readings so they are easier to read.

• The AM520 always takes a measurement once every second
regardless of the Time Constant selected. Using a Time
Constant greater than one second results in displayed reading s
that are averages of the 1-second readings. For example, a
10-second Time Constant will cause the display to show an
average of the most recent ten 1-second readings. This result s
in a 10-second moving average, updated on the display every
second.

• DO NOT confuse Time Constants with Log Intervals. Time
Constants affect only the AM520 display. Log Intervals affect
only the recorded readings. Therefore, the recorded logged
data will generally not match the displayed log data.

• When using general Alarms or STEL Alarms, the alarm is
triggered based on the displayed Time-Constant reading, not
the value of the logged data over the Log Interval. Therefore,
the recorded logged data will generally not match the alarm
values exactly. For instance, if a Time Constant of 30 seconds
and a Log Interval of one second are chosen, the displayed
reading will be smoothed out over 30 seconds. Since the
Alarms trigger from the displayed value and not the logged
value, there could be one or more data points saved in the
logged Test with values above the Alarm setting, but if the
average over 30 seconds is less than the Alarm setting, the
Alarm will not trigger.

Calibration

The calibration (CAL) factor is a multiplier that is applied to the raw
data prior to being displayed or recorded. The purpose of the
calibration factor is to compensate the readings for aerosols that have
different photometric properties than the aerosol used during factory
calibration.

Operation

27

Effect of Calibration Factors on Full Scale and Alarms

• Note that the AM520 maximum full scale reading is not fixed at
100 mg/m³; it changes when the Calibration Factor is changed.

• For instance, if a Calibration factor of 2.00 is chosen, all
readings are multiplied by 2.00, and the effective maximum full
scale reading of the AM520 is then 200 mg/m³.

• Since the range of selectable Calibration factors is 0.10 to

10.00, the effective maximum full scale reading can be
anywhere between 10.0 and 1000 mg/m³.

• Since the Alarm value must be allowed to approach full scale,
the maximum Alarm value is 999 mg/m³. This creates a
situation where the Alarm value can be set higher than the
AM520 maximum full scale reading. In this case, the AM520 will
never be able to read high enough to trigger the Alarm.

• To prevent this situation, the AM520 displays the message
“Warning: Alarm value is out of range” if you try to enter a
value that is out of range.

There are three items on the Calibration
menu.

• Zero Cal: This activates a function
which re-zeroes the measurement using
a filter.

• Flow Cal: This activates a function
which allows you to set the pump
voltage to achieve the desired sample
flow.

• User Cal: This allows you to select a
photometric calibration factor to adjust
the instrument response to more closely
match the properties of the aerosol
being measured.

Chapter 3

28

Zero Cal

For best results, it is important to zero the
AM520 before each test. This ensures
accurate data, especially for low aerosol
concentrations. The process only takes a
few minutes.

1. Locate the zero filter provided with the
AM520 kit and attach it to the inlet of the
SidePak monitor.

2. Start the AM520 by pressing the ESC
key. After the monitor goes into
SURVEY mode, press the ESC key to
reach the MAIN MENU.

3. Under MAIN MENU, use the ▲ ▼ keys
to scroll to CALIBRATION and press ↵.

4. Under the CALIBRATION menu, use
the ▲ ▼ keys to scroll to Zero Cal and
press ↵.

5. The AM520 will prompt you to attach the zero filter to the inlet of
the AM520. When the zero filter is connected, press ↵.

6. The AM520 will count-down from 60 to 0 and display Zero Cal
Complete.

7. Press the RETURN key to return to the CALIBRATION men.

8. The instrument is now ready to make accurate measurements.

Operation

29

Flow Cal

Aerosol concentration measurements with the
SidePak AM520 are accurate regardless of
the flow rate through the instrument. However,
size-selective aerosol sampling inlets such as
impactors and cyclones require specific flow
rates to function within their design
specifications. If using a size-selective inlet,
adjust the flow rate precisely. It's always a
good practice to adjust the flow rate before
the start of a sampling session.

AM520 connected to TSI 4146 Flow meter (sold separately)

To adjust the flow rate, you will need a flow calibrator. This can be a
simple rotameter or a precision flow calibrator often used for setting
the flow on personal sampling pumps. A flow calibrator is an optional
item and is not included with standard AM520 kits.

1. Connect a flow calibrator to the AM520 inlet.

2. Start the AM520 by pressing the ESC key. After the SidePak
monitor goes into SURVEY mode, press the ↵ key to reach the
MAIN MENU.

3. Under MAIN MENU, use the ▲ ▼ keys to scroll to

Alarms

The unit is equipped with two alarm types:

• General Alarm

• STEL Alarm

Both the General Alarm and the STEL Alarm have five default alarm
settings: 0.5 mg/m

3

, 1 mg/m3, 3 mg/m3, 5 mg/m3, and 15 mg/m3 and

OFF.
TrakPro™ v5 software can be used to set alarm values from 0.001 to

999 mg/m

3

.

A General Alarm is active during Survey mode and while data
logging. If the displayed Time-Constant reading exceeds the Alarm
value, the alarm triggers. Depending on settings in the ALARMS
menu, the display will flash red or the LEDs on the membrane switch
may flash or an audible beeper may sound. All three of those alarm
indications can be turned ON/OFF through the ALARMS menu.

Once triggered, the Alarm stays active until the displayed reading
drops below 95% of the Alarm value. The alarm can be “delayed” or
“muted” with the Ringback delay function. If the displayed reading is
more than 90% of the Alarm value, the display flashes yellow.

A STEL Alarm is active during data logging only and is not active in
Survey mode. If the displayed Time-Constant reading exceeds the
STEL Alarm value, the STEL Alarm triggers. When the STEL Alarm
triggers, a STEL Record is started in the logged data. A STEL Record
contains the average concentration taken every minute during the
length of the STEL Record.

Operation

33

STEL Record length is selectable from 5 to 30 minutes through
TrakPro™ software. Since the start of a STEL Record is not usually
aligned with the Log Interval, the values of averages saved in the
STEL Record will generally not match the values saved each Log
Interval.

Ringback delay: The Ringback delay is a user
function that will “mute” an activated alarm for
the selected period of time. General Alarms
and STEL Alarms can be muted for the
duration of the Ringback delay setting:
30 sec, 1 min, 3 min, 5 min, 10 min, off. After
the Ringback delay expires, the Alarm will
sound again.

When an alarm sounds, the Ringback delay
can be activated by pressing the ↵ button.
The Ringback delay button is functional even
when the front panel is locked.

Maintenance

The SidePak™ AM520 Personal Aerosol Monitor requires periodic
maintenance. The most common procedures are:

• General Cleaning

• Impactor maintenance

• Cyclone maintenance

• Charging batteries

• Zeroing

In addition to the procedures in this chapter, TSI recommends that
you return your SidePak

AM520 Personal Aerosol Monitor to the

factory for annual calibration. Regular factory-authorized cleaning and
recalibration helps ensure that your instrument is working properly,
has the latest updates, and will provide accurate and reliable
measurements.

Returning the Instrument to TSI for Service

When sending the instrument to TSI for repair or service, include all
parts and accessories. To troubleshoot a problem, a TSI Technician
will attempt to recreate the problem by running the instrument. All
equipment used with the instrument is needed to do this.

WARNING/AVERTISSEMENT

Remove LiON batteries from instrument before shipping. DO NOT ship
AM520 with batteries installed.

Chapter 4

36

General Cleaning

General cleaning of the SidePak AM520 case should be done with
soap and water applied with a damp cloth. Do not use chemical
cleaners, alcohol or petroleum derived cleaners on the case or front
panel of the instrument.

Use a foam or lint-free swab to clean the alarm vents on the front of
the unit. Do not use high pressure compressed air as this may harm
the internal membrane of the alarm horn and re-aerosolize particulate
matter.

Using and Maintaining Built-in Impactors

The standard inlet on the SidePak AM520
was designed not to cause any specific
particle size separations. It is intended for
use with external size-selective aerosol
samplers such as a cyclone or external
impactor at any flow rate within the
allowable range. The standard inlet can be
differentiated from the built-in impactor by
the absence of a particle size marking on
the side and top.

The AM520 includes a set of four impactors that can be used in place
of the standard inlet to conveniently separate specific particle size
fractions. The 50% cut-off size is marked in micrometers (μ) on each
impactor. The four impactors provide cuts at 1.0μ, 2.5μ, 5μ, and 10μ,
corresponding to PM

1.0

, PM

2.5

, PM5, and PM10 specifications
respectively. All inlets are made of conductive plastic to eliminate
particle losses due to static charges.

Note

SidePak monitor built-in impactors must be operated with the flow
rate set to 1.7 L/min for proper performance. Using other flow rates
will result in unknown particle size fractions. The standard inlet can
be used at any flow rate.

Always use the standard (unmarked) inlet when sampling through an
external size-selective sampler such as a cyclone or external
impactor.

Maintenance

37

SidePak size-selective inlets use an
internal impactor disk. The impactor disk
functions as a collection plate where
particles larger than the cut-size are
trapped. The same impactor disk is
used for all impactors, but it is not used
for the standard inlet.

To make sure unwanted (large) particles
remain trapped on the impactor disk, it
is necessary to apply 1 to 4 drops of impactor oil on the impactor disk
for particles to stick to. Wipe off any excess oil if necessary.

Note

Size-selective impactors will not function unless an impactor disk is
installed. To ensure proper performance, the impactor disk should be
removed, cleaned and re-oiled prior to each use.

1. Remove the i m pactor by loosening the two captive screws that
hold the impactor in place.

2 Flip the AM520 upside down to

remove the impactor disk.

Chapter 4

38

3 Clean the impactor inlet and

impactor disk with a clean lint-free
swab or microfiber cloth and light
solvent. Gently blow impactor
body dry with canned/pressurized
clean air or allow to air dry. Use a
lint-free swab or microfiber cloth
to clean impactor well inside the
instrument case to remove
accumulated particles.

WARNING/

AVERTISSEMENT

To prevent driving contamination
into the optics, never blow air
directly into the sample inlet
opening of the AM520.

4 Apply 1 to 4 drops of oil to the top

of the impactor disk (collection
plate). Wipe off excess oil if
necessary.

5 Slide the impactor disk into the

impactor well until it is seated.

Maintenance

39

6 Add impactor inlet.

7 Screw the impactor assembly

back onto the AM520 body and
tighten the two captive screws. To
avoid damage, DO NOT
over-tighten.

Using and Maintaining the Respirable Cyclone

The 10-mm Nylon Dorr-Oliver Cyclone included with the AM520 can
be used to differentiate between the respirable fraction and other
portions of the ambient aerosol. It is ideal for making breathing zone
measurements because it can be attached to a worker's clothing near
his or her head. TSI supplies a U-tube and clip with the cyclone
specifically for this purpose.

4 µm is internationally accepted as the 50% cut-off size for respirable
aerosols. Particles larger than 4 µm impact onto the surfaces of the
upper respiratory tract and cannot reach the lungs. The cyclone
accessory provided with SidePak AM520 is designed to provide a cut­off at 4 µm. This is specified as a 50% cut-off at 4 µm.

Chapter 4

40

The cyclone works by forcing the particle-laden air sample to swirl
inside the cyclone body. Larger (higher mass) particles cannot follow
the air stream and become trapped while smaller particles stay in the
air stream and pass through. When using the cyclone, assume that all
particles smaller than the cut-off size pass through and all larger
particles become trapped in the grit potentiometer.

The cut-off size for any cyclone is dependent on flow rate.

Note

It is very important that the sample flow rate through the SidePak
AM520 monitor be set at 1.7 liters per minute (L/min). If some other
flow rate is set, the cut-off size will be unknown.

1. Install the sta ndard inlet (unmarked) on the SidePak AM520 body
without an impactor disk inside.

2. Attach the cyclone and sample tube onto the AM520 inlet.

3. Adjust the flow rate of the AM520 to 1.7 L/min. See the Operation
chapter for instructions on setting the flow rate.

The SidePak monitor and cyclone are now ready to use. Attach the
cyclone to the individual test subject's clothing using the U-tube an d
clip provided with the cyclone.

Cleaning the Cyclone

The 10-mm Nylon Dorr-Oliver Cyclone should be cleaned prior to
each use. In most cases, simply cleaning the grit potentiometer is all
that is necessary. Inspect the inside of the cyclone body regularly and
clean it if necessary.

1. Un screw the grit potentiometer from the bottom of the cyclone.
Remove the stainless steel cyclone clip and pull the cap off.

2. Hold the o pe n end of the grit potentiometer down and tap it on a
hard surface to dislodge particles. Repeat with the cyclone bo dy.

Note

If dirt is visible inside either the grit potentiometer or the cyclone
body, it may be necessary to blow canned/pressurized air into the
cyclone parts and/or to clean them with soap and water. A mild
solvent like isopropanol may also be used inside the cyclone. Make
certain that the cyclone is perfectly dry before re-assembly and use.

Maintenance

41

3. Re-assemble the cyclone. Note that the stainless steel cyclone
clip that holds the cap onto the body will only fit one way. The
cyclone cleaning procedure is now compl eted.

Using and Maintaining the Diesel Particulate Matter
DPM Cyclone

The DPM Cyclone included with the AM520 can be used to
differentiate between the diesel particulate matter and other portions
of the ambient aerosol. It is ideal for making breathing zone
measurements because it can be attached to clothing near the
wearers face/breathing zone. TSI supplies a U-tube, clip, and a Dorr­Oliver cyclone with the DPM cyclone specifically for this purpose.

The DPM cyclone is designed with a 50 percent cut-off size of

0.8 µm. The Dorr-Oliver cyclone is positioned upstream of the DPM

cyclone to filter out particles larger than 4 µm preventing large
particles from clogging the inlet of the DPM cyclone.

Chapter 4

42

The cyclone works by forcing the particle-laden air sample to swirl
inside the cyclone body. Larger (higher mass) particles cannot follow
the air stream and become trapped while smaller particles stay in the
air stream and pass through. When using the cyclone, you can
assume that all particles smaller than the cut-off size pass through
and all larger particles become trapped in the grit potentiometer.

The cut-off size for any cyclone is dependent on flow rate.

Note

It is very important that the sample flow rate through the SidePak
monitor be set at 1.7 liters per minute (L/min). If some other flow rate
is set, the cut-off size will be unknown.

1. Be sure to ha ve the standard inlet (unmarked) installed on the
SidePak AM520 body and that there is no impactor disk inside.

2. Attach the Do rr-Oliver
cyclone to the DPM
cyclone to create the DPM
assembly.

3. Attach the DPM
cyclone assembly

Cleaning the Diesel Particulate Matter DPM Cyclone

The DPM Cyclone should be cleaned prior to each use. In most
cases, simply cleaning the grit potentiometer is all that is needed.
Inspect the inside of the cyclone body regularly and clean it if
necessary.

1. Unscrew the grit potentiometer from the bottom of the cyclone.
Remove the stainless steel cyclone clip and pull the cap off.

2. Hold the open end of the grit potentiometer down and tap it on a
hard surface to dislodge particles. Repeat with the cyclone body.

Note

If dirt is visible inside either the grit potentiometer or the cyclone body,
it may be necessary to blow canned/pressurized air into the cyclone
parts and/or to clean them with soap and water. A mild solvent like
isopropanol may also be used inside the cyclone. Make certain that
the cyclone is perfectly dry before re-assembly and use.

3. Re-asse mble the cyclone. Note
that the stainless steel cyclone clip
that holds the cap onto the body
will only fit one way. The cyclone
cleaning procedure is now
completed.

Custom Calibrations

In most situations, the Model AM520 provides very good information
on how the concentration of an aerosol changes for over time.
Factory calibration to the respirable fraction of standard ISO 12103-1,
A1 Test Dust (aka, Arizona Test Dust) allows comparisons between
measurements where the source or type of dust is predominately the
same. Because optical mass measurements are dependent upon
particle size and material properties, there may be times when a
custom calibration will improve your accuracy for a specific aerosol.

The SidePak™ AM520 monitor has several features to aid in
obtaining good accuracy for a specific aerosol.

• The SidePak monitor’s photometric calibration factor can be

changed through the instrument keypad. All future readings from
the SidePak monitor will correspond to a specific aerosol until the
calibration factor is changed back to the factory setting.

• Photometric calibration factors can be stored in a table and

downloaded to the SidePak monitor using the TrakPro Data
Analysis Software. All future measurements will correspond to a
specific aerosol until the calibration factor is changed back to the
factory setting.

• A single set of logged data can be converted to data calibrated to

a specific aerosol with the use of the TrakPro software. This
conversion can be done by knowing either the true mass
concentration for the logged data or the calibration factor for the
aerosol. Future measurements will continue to be read and
logged with the original calibration factor (normally 1.0) and will
not be converted automatically.

All of these options require that a true mass concentration (via
gravimetric analysis) is determined for the aerosol measured. The
true mass concentration is used to calculate the photometric
calibration factor for that aerosol. Once a photometric calibration
factor is developed, it can be used repeatedly to improve
measurements in the same or similar aerosol environment.

Appendix B

62

Developing a Photometric Calibration Factor for a
Specific Aerosol

The SidePak AM520 Personal Aerosol Monitor is factory calibrated to
the respirable fraction of standard ISO 12103-1, A1 Test Dust. The
SidePak AM520 monitor can be easily calibrated to any arbitrary
aerosol by adjusting the photometric calibration factor. The SidePak
monitor’s photometric calibration factor is assigned the value of 1.00
(factory setting) for the standard ISO test dust. This procedure
describes how to determine the photometric calibrati on factor for a
specific aerosol. Using a photometric calibration factor value of 1.00
will always revert back to the factory calibration.

To determine a new photometric calibration factor, a reference
instrument is needed to accurately measure the concentration of
aerosol. Gravimetric analysis is often the best choice, although it is
limited to nonvolatile aerosols.

To develop an accurate photometric calibration factor, a simultaneous
measure must be made of the aerosol concentration with the SidePak
AM520 monitor and the reference instrument.

Note

See Application Note EXPMN-014 Developing Photometric
Calibration Factor for Respirable Silica, and Application Note
EXPMN-013 Developing Photometric Calibration Factors for Die sel
Particulate Matter.

Photometric Calibration Factor Procedure

1. Set up photo meter and sampling pump in similar manner.

• SidePak AM520 (with Dorr-Oliver Cyclone if measuring
respirable size fraction.

• Sample pump with a sampling cassette (with Dorr-Oliver
Cyclone if measuring respirable size fraction)

2. Adjust flow ra te for appropriate inlet conditioner (if used).

• Flow rate set to 1.7 L/min for both instruments if using
Dorr-Oliver Cyclone.

3. Zero the p hotometer and calibrate the sample pump prior to
sampling.

4. Co-locate both samplers side-by-side either in a work area or on
a worker in the breathing zone.

Custom Calibrations

63

5. Start photom eter and sampling pump at same time, sample for
same duration.

• Data log aerosol measurements with photometer.

• Collect gravimetric sample with sample pump.

• Sample time does not need to be full shift like compliance

monitoring. The key is to collect at least the minimum volume
necessary for valid analysis with the analytical method.

6. Sample a few locations to gather data. (Note: Ideally use a

statistically significant number of samples to properly represent
the worker population.)

• Review gravimetric data as it becomes available.

• Conduct more sampling if considerable data variability is

found.

7. Send gravimetric samples to accredited analytical lab.

8. Comp are photometric and gravimetric data.

• Calculate averages for each from representative number of

samples.

• If sample variability is high, collect more samples to improve

the representation of the sample population.

9. Cal culate new photometric calibration factor using the formula
below.

PCF= Photometric Calibration Factor

Reference Concentration = Average Gravimetric Concentration
Data Log Concentration = Average Photometric Concentration
ECF = Existing Calibration Factor (by

default Factory calibration is 1.0)

×

10. Enter new Photometric Calibration Factor into the photometer.

11. Repeat the co-located, paired sampling process using new PCF
setting in photometer.

Note: Conducting at least one additional pair-sample set using
the new PCF will help to verify the photometric calibration factor
is applicable to the reference aerosol.

Appendix B

64

12. Compare gravimetric and PCF photometric sample data.

• Results should be closer, “more accurate,” using the new
PCF.

Note

Greater accuracy will be obtained with longer samples. The time you
permit for sampling often depends on the reference instrument and
characteristics of the measured aerosol. It may take some time to
collect sufficient aerosol onto a filter cassette for accurate gravimetric
analysis. Refer to instructions of your reference instrument for
sampling times.

65

Appendix C

Converting Stored Data to Calibrated Data

A single set of logged data can be converted to data calibrated to a
specific aerosol with the use of the TrakPro™ Data Analysis
Software. This conversion can be done by knowing either the true
mass concentration for the logged data or the calibration factor for the
aerosol. To perform this conversion, refer to the TrakPro manual.
