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/AM520i 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. The coin cell is not user-serviceable.

NOTE

Only the AM520i is rated intrinsically safe for use in hazardous locations when operated in accordance to this manual.

Installing and Charging the Lithium Ion Rechargeable Battery Pack

Battery packs slide on and off the AM520/AM520i in the direction shown below:

NOTE

Plug in power cord and charge fully before turning on instrument the first time. See Smart Battery Management™ System

technology below.

8 Chapter 2

Installing the Lithium Ion Battery Pack

1. Place the battery pack under

the AM520/AM520i.

2. Push firmly to slide into place.

3. Fasten it in place using the

two battery screws provided.

Setting Up 9

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.

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.

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 instrument. The SBMS supervisor also prevents excessive discharge when the battery is depleted.

10 Chapter 2

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.

Setting Up 11

W A R N I N G

Remove Li-ion battery during storage and transportation of instrument.

Using the AC Adapter (power supply)

The AC adapter powers the AM520/AM520i 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.

Normal charge time is about four (4) hours with the instrument off or when the battery is removed from the instrument.

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.

12 Chapter 2

Battery Icon on Display

When the battery is charging, the battery icon on the instrument 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/AM520i will display a “LOW BATTERY” message for 5 seconds and then turn itself off.

Displayed Battery Life

The AM520/AM520i shows battery life remaining in Hours:Minutes or Minutes (user selectable) when displaying the Survey mode menu or while actively data logging and showing the Logging menu. Those screens 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/AM520i 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.

Chapter 3

Operation

Overview

The SidePak™ Personal Aerosol Monitor is a miniature batteryoperated laser photometer that measures airborne particle massconcentration in units of milligrams per cubic meter (mg/m3).

The built-in sampling pump flow rate is user-adjustable; giving the user the flexibility to attach a wide variety of inlet conditioners to sample from the worker’s breathing zone or other locations. The rugged belt-mountable unit is small, quiet, and lightweight, minimizing interference and discomfort for the wearer. The high resolution OLED display shows aerosol concentration and 8-hour TWA (time-weighted average) in real time. Information can be stored and later downloaded via a Windows®-based PC using the enclosed TrakPro™ software and USB (Universal Serial Bus) communications cable.

Data Logging

The AM520/AM520i can log data in either:

• Manual logging mode, or

• Program logging mode.

To run the instrument in Manual logging mode, select Manual Mode from the RUN MODE menu and press the ENTER key.

The instrument will immediately start logging and it will use the Log Interval (set in the Log Interval option of the SETTINGS menu). Manual logging stops automatically when logging memory is full or the ESC key is pressed.

To run the AM520/AM520i in Program logging mode, select the desired program logging mode from the RUN MODE menu, and press ENTER. There are five program logging modes available. The default names are “Prog 1” through “Prog 5”. These can be renamed and the values set using TrakPro™ Data Analysis Software. If a specific start time or date was selected using TrakPro™ software, the instrument will wait until the start time and then automatically begin logging. If the start time/date is in the past, the instrument will show the error message "Invalid start time."

If the instrument is programmed to wait before logging, it will show a

“PROG DELAY” screen with the current time/date and the

programmed start time/date. If the starting time/date is more than one minute in the future, the instrument will turn off the pump and laser in order to save power.

Chapter 3

The “PROG DELAY” screen will disappear

after a few seconds and “PROG DELAY”

will flash briefly once every two seconds to show that the instrument is waiting to start. If a key is pressed while the instrument is

waiting, it will show the full “PROG DELAY”

screen again.

Programmed logging mode uses start and stop time/date, logging interval, Test length, number of Tests, and wait time between Tests programmed in TrakPro™ software.

While data logging is active, the screen can be toggled back and forth between the LOGGING DATA menu and the screen saver. The LOGGING DATA menu displays:

• Real-time aerosol concentration in units of milligrams per cubic meter (mg/m³)

Logging, above. The test is stopped by pressing ESC then ENTER.

While running a manual test, the display shows LOGGING DATA as well as the time constant concentration. Manual tests use the logging interval defined in Log Interval under the SETTINGS menu.

Each test is assigned a sequential number (for example, TEST#1, TEST#2, … TEST#100) until memory is used up or cleared.

Press  or ESC to stop a test in progress. The instrument will ask to confirm to stop the test or not, while data logging continues. If ESC is pressed to continue, there will be no break in the logged data.

Program Mode 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.

Chapter 3

During data logging, use the ESC key to view:

• Battery life remaining displayed in minutes

• 8-hour TWA

• Elapsed time

• Current time and date

If the user-selectable screen save delay elapses without a key being pressed, the display reverts back to the LOGGING DATA screen saver.

To stop a test, press the ESC key. The instrument 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 instrument will display the message “Logging Stopped” and show whether any data was saved. If the test is stopped before any data points have been recorded, 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.

Settings

Access the SETTINGS menu from the

MAIN MENU, then use the ▼ key to select

SETTINGS and press . The SETTINGS menu provides access to

the following items. Use the ▲ ▼ keys to

select the item you want to access and press . Each selection is described in detail below.

• Log Interval

• Time Constant

• Time/Date

• Battery Units

• Screen Save Delay

• Language

• Information

Operation

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/AM520i 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 mistake log intervals with Time Constant. Log intervals only affect recorded readings. Time Constant only affects the AM520/AM520i 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 want 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

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 instruments display only. DO NOT mistake Time Constant with logging intervals. Time Constant only affects the display. Log intervals only affect recorded readings.

The SidePak™ AM520/AM520i 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 want 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

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/AM520i 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/AM520i always takes a measurement once 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. This results in a 10-second moving average, updated on the display every second.

• DO NOT mistake “Time Constants” with “Log Intervals.” Time Constants affect only the 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

Effect of Calibration Factors on Full Scale and Alarms

• Note that the instrument 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 instrument 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 maximum full scale reading. In this case, the instrument will never be able to read high enough to trigger the Alarm.

• To prevent this situation, the instrument 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

Zeroing the Instrument (Zero Cal)

For best results, it is important to zero the instrument 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/AM520i kit and attach it to the inlet of the SidePak™ monitor.

2. Start the instrument 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 instrument will prompt you to attach the zero filter to the inlet. When the zero filter is connected, press .

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

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

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

Operation

Flow Cal

Aerosol concentration measurements with the SidePak™ AM520/AM520i monitor 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 is 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/AM520i kits.

1. Connect a flow calibrator to the inlet.

2. Start the instrument 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 CALIBRATION and press .

4. Under the CALIBRATION menu, use the ▲ ▼ keys to select FLOW CAL and press .

5. Press .

6. Each single click of an ▲ ▼ key changes the flow by 1 percent of the available range. The flow rate can be changed more quickly by holding the arrow key down. The range is 0 to 200.

2. Under DATA menu, select Clear Memory with the ▲ ▼ keys and press .

3. You will be prompted to confirm your intention.

4. Press Enter. You will be returned to the Data menu.

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/m3, 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/m3.

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

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.

Chapter 4

Maintenance

The SidePak™ AM520/AM520i Personal Aerosol Monitor requires periodic maintenance. The most common procedures are:

• General cleaning

• Impactor maintenance

• Cyclone maintenance

• Charging batteries

• Zeroing the Instrument

In addition to the procedures in this chapter, TSI® recommends that you return your SidePak™ AM520/AM520i 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.

W A R N I N G

Remove Li-ion batteries from instrument before shipping. DO NOT ship AM520/AM520i with batteries installed.

General Cleaning

General cleaning of the SidePak™ AM520/AM520i case should be done with soap and water applied with a damp cloth.

NOTE

DO NOT use chemical cleaners, alcohol or petroleum derived

cleaners on the case or front panel of the instrument.

Chapter 4

Use a foam or lint-free swab to clean the alarm vents on the front of the unit.

NOTE

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

Included with the instrument is a set of four impactor inlets and gaskets 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 (μm) on each

inlet. The four impactor inlets provide cuts at 1.0 μm, 2.5 μm, 5 μm, and 10 μm, 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.

The “standard inlet” does not have a size marking on the top edge

and does not 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. When using a cyclone or external impactor, the impactor disk should not be used.

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

SidePak™ size-selective inlets are used with an internal impactor disk (provided). 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 impactor by loosening the two captive screws that hold the impactor in place.

2. Flip the instrument upside down to remove the impactor disk.

Chapter 4

3. Clean the impactor inlet and impactor disk with a clean lintfree 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.

WAR NI NG

To prevent driving contamination into the optics, never blow air directly into the sample inlet opening of the AM520/AM520i.

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

6. Place inlet gasket on the inlet so that the tabs on the gasket fit inside the inlet around inner tabs of the inlet as shown.

7. Place impactor inlet on instrument.

8. Secure the impactor assembly back onto the instrument body by tightening the two captive screws. To avoid damage, DO NOT over-tighten.

Chapter 4

Using and Maintaining the Respirable Cyclone

The 10-mm Nylon Dorr-Oliver Cyclone included with the AM520/AM520i 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/AM520i is designed to provide a cut-off at 4 µm. This is specified as a 50% cut-off at 4 µm.

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/AM520i 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 standard inlet (unmarked) on the SidePak™ AM520/AM520i body without an impactor disk inside.

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

3. Adjust the flow rate 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 and clip provided with the cyclone.

Maintenance

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. 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-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 completed.

Using and Maintaining the Diesel Particulate Matter DPM Cyclone

The DPM Cyclone included with the AM520/AM520i 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.

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.

Maintenance

1. When using the cyclone, be sure that there is no impactor disk installed. Use the standard inlet (unmarked) with gasket.

2. Attach the Dorr-Oliver cyclone to the DPM cyclone to create the DPM assembly.

3. Attach the DPM cyclone assembly and sample tube onto the inlet.

4. Adjust the flow rate to 1.7 L/min. See

Chapter 3, “Operation” for

instructions on how to set the flow rate.

Appendix B

Custom Calibrations

In most situations, the Model AM520/AM520i 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/AM520i 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

Developing a Photometric Calibration Factor for a Specific Aerosol

The SidePak™ AM520/AM520i Personal Aerosol Monitor is factory calibrated to the respirable fraction of standard ISO 12103-1, A1 Test Dust. The SidePak™ AM520/AM520i 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 calibration 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/AM520i 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 Diesel Particulate Matter.

Photometric Calibration Factor Procedure

1. Set up photometer and sampling pump in similar manner.

• SidePak™ AM520/AM520i (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 rate 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 photometer 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

5. Start photometer 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. Compare 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. Calculate 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)

𝑷𝑪𝑭 =

𝑹𝒆𝒇𝒆𝒓𝒆𝒏𝒄𝒆 𝑪𝒐𝒏𝒄𝒆𝒏𝒕𝒓𝒂𝒕𝒊𝒐𝒏

𝑫𝒂𝒕𝒂 𝑳𝒐𝒈 𝑪𝒐𝒏𝒄𝒆𝒏𝒕𝒓𝒂𝒕𝒊𝒐𝒏

× 𝑬𝑪𝑭

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

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.

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™ software manual.
