Using the AC Adapter to Run Instrument

The AC adapter allows you to power the D

USTTRAK™ monitor from an AC

wall outlet. When using th e AC adapter, the batteries (if installed) will be
bypassed.

Battery Charging

This instrument will charge the Lithium Ion battery packs. Insert the
batteries into the battery compartment, plug the instrument into AC power,
and turn the instrument on. Batteries will charge only when the instrument is
on and in stand-by mode. Batteries will not be charged if the instrument is
turned off or is actively taken measurements. Charging will stop when the
batteries have been fully charged.

Inlet Cap

When using the D

USTTRAK™ monitor to sample environmental air, the inlet

cap should be put over the instrument. This cap will keep large objects from
dropping into and plugging the inlet. The cap will also keep direct light fro m
shinning into the chamber and skewing the results.

The inlet cap can simply be pressed onto the instruments inlet.

Flow Cal

Flow Cal is run if the user wants to change the flow set point. The flow set
point is factory set to 3 L/min total flow. 2 L/min of the total flow is
measured aerosol flow. 1 L/min of total flow is split off, filtered and used for
sheath flow. There is an internal ∆P flowmeter in the D

USTTRAK™ II

instrument that controls flow rate to ±5% if factory setpoint. It is
recommended to check the flows with an external flow reference meter,
especially when collecting data. The pump will automatically start when
entering the Flow Cal screen.

1. Attach a flow calibrator (reference flow meter) to inlet port. You may

use a bubble buret, mass flow meter, dry piston or rotameter as flow
measurement devices.

2. Move the arrows up or down to achieve desired flow on the reference

flowmeter. Each up or down arrow will change the flow about 1%.
Allow time between button presses to let pump change to the new
flow rate.

3. Select save once the desired flow rate is achieved. Select Undo to return

to the factory set point.

selected user calibration.

Photometric Calibration Factor

In most situations, the D

USTTRAK™ monitor with its built-in data logging

capability can provide very good information on how the concentration of an
aerosol changes for different pro ces ses o ver time. Factory calibration to the
respirable fraction of standard ISO 12103-1, A1 test dust is fairly
representative of a wide variety of ambient aerosols. Because o ptical mass
measurements are dependent upon particle size and material properties, there
may be times in which a custom calibration would improve your accuracy
for a specific aerosol.

Determining a aerosol specific photometric calibration requires that you
determine a true mass concentration (e.g., gravimetric analysis) for the
aerosol you want to measure. The true mass concentration is used to
calculate the custom calibration factor for that aerosol. Once you have a
custom calibration factor, you can reuse it each time you make
measurements in the same aerosol environment.

Determining the Calibration Factor for a Specific Aerosol

The D

USTTRAK™ II monitor is factory calibrated to the resp irable fraction of

standard ISO 12103-1, A1 test dust. The D

USTTRAK™ monitor can be easily

calibrated to any arbitrary aerosol by adjusting the custom calibration factor.
The D

USTTRAK™ monitor’s custom calibration factor is assigned the value

of 1.00 for the factory calibration to standard ISO test dust. This procedure
describes how to determine the calibration factor fo r a specific aerosol.
Using the value of 1.00 will always revert back to the factory calibration.

To determine a new calibration factor you need some way of accurately
measuring the concentration of aerosol, hereafter ref er red to as the reference
instrument. A gravimetric analysis is often the be s t choice, though it is
limited to nonvolatile aerosols. The internal 37 mm filter cartridge, in the
desktop units, can be used to collect the reference gr avimetric
reference sample.

Operation

23

To make an accurate calibration you must simultaneously measure the
aerosol concentration with the D

USTTRAK™ monitor and your reference

instrument.

1. Zero the D

USTTRAK™ II monitor.

2. Put the instrument in Manual Log (Manual Logging is reviewed later in

this section).

3. Set the logging interval. One minute (i.e., “01:00”) is often a good

choice.

4. Co-locate the D

USTTRAK™ II monitor and the reference sampler

together so that they are measuring from the same area. The 37mm filter
cartridge in the desktop unit can be used to collect the particles to be
weighed for the gravimetric reference.

5. Start sampling aerosol with both instruments at the same time.

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 suffic ient aerosol onto a filter cassette
for accurate gravimetric analysis. Refer to instructions of your
reference instrument for sampling tim es.

6. Stop sampling w ith both instruments at the same time.

7. Record the D

USTTRAK™ monitor average concentration. This can be

done by viewing the sample average in the Data screen. (Data Screen is
reviewed later in this chapter)

8. Determine the mass concentration in mg/m

3

from your reference
instrument. For gravimetric sampling this means having the gravimetric
sample weighed.

Note

If you used the internal gravimetric filter in the DustTrak™ Model
8530 or 8531, the flow rate used to compute the concentration
should be 2 L/min, not 3 L/min since only 2 L/min of aerosol flow
reaches the filter.

9. Compute the new calibration constant, NewCal, using the following

formula:

Alarm

Alarm allows the user to set an alarm level that will be triggered if the
instrument’s reading goes above the setpoint.

Alarm1 Setpoint [mg/m3]

The alarm1 setpoint is the mass
concentration level upon which the
alarm1 is triggered.

Alarm will be triggered if the mass
concentration, taken at the logging
interval, rises above the setpoint.

Note: Alarm 2 must be lower than Alarm
1 when both alarms are enabled.

data will be collected when Alarm1 level
is surpassed.

STEL selection is available on the 8530
and 8531 desktop models only.

See STEL Note below.

Alarm2 Setpoint [mg/m3]

The alarm2 setpoint is the mass
concentration level upon which the
alarm2 is triggered.

Alarm will be triggered if the mass
concentration, taken at the logging
interval, rises above the setpoint.

Note: Alarm 2 must be lower than Alarm
1 when both alarms are enabled

Alarm2 Enable [On, Off]

Enables Alarm2 to be logged and will
activate the Audible or Visible alarms if
they are enabled.

Alarm Audible [On, Off]

When the audible alarm is turned on, the
instrument will activate internal beeper

Maintenance

The D

USTTRAK™ II aerosol monitor can be maintained in the field using the

instructions below. Additionally, TSI recommends that you return your
D

USTTRAK™ II to the factory for annual calibration. For a reasonable fee,

we will quickly clean and calibrate the unit and return it to you in “as new”
working condition, along with a Certificate of Calibration. This “annual
checkup” helps ensure that the D

USTTRAK™ II is always in good operating

condition.

WARNING

There are no user-serviceable parts insi de this
instrument. The instrument s houl d only be opened by TSI
or a TSI approved service technician.

Maintenance Schedule

Your DUSTTRAK™ II Aerosol Monitor requires maintenance on a regular
basis. Table 4–1 lists the factory recommended maintenance schedule.

Some maintenance items are required each time the D

USTTRAK™ monitor is

used or on an annual basis. Other items are scheduled according to how
much aerosol is drawn through the instrument. For example, cleaning the
inlet sample tube is recommended after 350 hours of sampling a 1 mg/m

3

concentration of aerosol. This recommendation should be pro-rated
according to how the instrument is used. 350 hours at 1 mg/m

3

is the same

amount of aerosol as 700 hours at 0.5 mg/m

3

or 175 hours at 2 mg/m3, etc.

Table 4–1. Recommended Maintenance Schedule

Item Frequency

Perform zero check Before each use.
Clean inlet 350 hr. at 1 mg/m3*
Clean 2.5 µm calibration impactor Before every use.
Replace internal filters 350 hr. at 1 mg/m3* or

when indicated by the main
screen filter error indicator.

Return to factory for cleaning and calibration Annually

*Pro-rated, see discussion above.

Chapter 4

40

The DUSTTRAK™ monitor keeps track of the accumulated amount of aerosol
drawn through it since its last cleaning. When the internal filter replacement
is due, the filter error indicator will turn from green to red.

TSI recommends that you perform a zero check prior to each use for the
D

USTTRAK™ monitor and certainly before running any extended tests, and

after the instrument experiences a significant environmental change.
Examples of significant environmental changes would be ambient
temperature changes that exceed 15

°F (8 °C) or moving from locations with

high aerosol concentrations to low concentrations.

Zero Module

The Zero Module (PN 801690) allows for automatic re-zeroing of the
D

USTTRAK™ Instrument during long sampling runs. The Zero Module

works only with the 8530 and 8531 desktop models.

The AutoZero module is attached to the main instrument in two steps. The
first step is to place the Zero module over the instrument’s inlet and press
down. The Zero module has an O-ring seal that will engage with the
instrument’s inlet.

Figure B-1: Place Zero Module Over Inlet and Press Down

The second step is attaching the cable from the Zero module to the Zero
module connector located on the back of the instrument.

Figure B-2: Zero Module Connector

Appendix B

54

The Zero Module can only be used in a program log mode. The Zero module
function is controlled through these two program mode options:

Auto Zero Interval

Interval between re-zeroing the instrument
using the Auto-Zero accessory.

Use Auto Zero

Select Yes to use the Zero Module. Select
No to not use the Zero Module.

Important points on Zero Module operation:

• The Zero module will take one (1) minute to take a zero reading. The

first 45 seconds of that period is used to clear the chamber of particles.
Readings from last 15 second of the period, when the chamber is
cleared of particles, will be averaged to determine the Zero offset.

• The log interval, when the Zero module is activated, must be two (2)

minutes or greater. Data will not be recorded to the log file when the
Zero module is activated.
