DUSTMATE AND AIRQ FOR WINDOWS
The DUSTMATE environmental monitor can be supplied with AirQ32 for Windows
software. This enables results stored in the DUSTMATE memory to be uploaded into
your PC when you have completed sampling. Additionally your PC can be used to
control and collect results from the DUSTMATE sensor in real time.
AirQ is designed to collect, manage and display data from a range of environment
sensors, either as individual sensors or in real-time when connected to a sensor
network. The sensors can be used to measure a whole range of environmental
quantities such as PM10 particles, airborne fibres, VOCs and pollutant gases.
AirQ is provided with extensive on-line help with hypertext links, clicking an
on-screen button with a blue question mark will automatically open the relevant
help page.

INSTALLATION OF AIR32Q
The program is supplied on CD and requires Windows 95 or above to operate. An
un-installer is provided with the program. Approximately 20 MB of free disk space is
required on drive C: to complete the installation
To install in Windows: Insert the CD it should launch automatically if not run
setup.exe, then follow the on-screen instructions.
AirQ32 will be installed in C:\Airq32. Sample results which can be imported, if

GETTING STARTED WITH DUSTMATE
Before starting connect a fully charged battery pack via the 6 pin
DIN connector
SWITCHING ON: To turn the instrument on, press and release the switched
marked [ON]. After a short self test (see below) the display will show
"DUSTMATE ready", together with the time and date. If the battery
needs re-charging, the display will show “DUSTMATE paused” and
continuously flash "Charge battery".
The battery must be fully re-charged as soon the "Charge battery"
warning appears.
SWITCHING OFF: Providing the instrument is not sampling it will switch itself off
automatically if no buttons have been pressed for 4 minutes. To manually
switch off the instrument press []and []together. The DUSTMATE will
not switch off while on-line to AirQ.
DISPLAY CONTRAST: To adjust the contrast of the display press and hold [RESET]
as the instrument is switched-on until the display goes black after about
3 seconds. Then use the []or []buttons to darken or lighten the
display respectively. Press [ENTER] when the required contrast is obtained.
DUSTMATE will automatically remember this setting and use it each time
it is switched-on. The contrast can only be adjusted as you switch the
instrument on, and once set to suit you it should not normally need re-
adjusting.
SELF TEST: As DUSTMATE is switched on it carries out certain self tests to make
sure it is working correctly. At the end of the self test the display will show
"Last Serviced at", this is the time and date when the instrument was
serviced. If this is more than a year ago, the display will show "PLEASE
HAVE ME FACTORY SERVICED" instead.

If the instrument detects a fault with its memory during the self test the
display will show "MEMORY ERROR".
If the instrument has a potential fault the display will show
"INSTRUMENT FAULT".
In both of the above cases, the instrument will automatically revert to its
default settings and may still usable - albeit with reduced accuracy. After
the error message, the display will show "PLEASE HAVE ME FACTORY
SERVICED". In this case please contact the factory as soon as possible.
MEMORY: If you press [RESET] while the display shows "DUSTMATE ready" or
during sampling, the display will switch to indicating the battery voltage,
internal case temperature and the percentage of memory used. Release
[RESET] to revert to the normal display. During dust sampling, when
[RESET] is released, the display will first show the sample number and
instrument location.
The fully charged battery voltage is about 6.4 volts (charger disconnected).
It is suggested that the battery is recharged if its voltage drops below
5.9 volts. Sampling will cease automatically and the display will indicate
“DUSTMATE paused” if the battery drops below about 5.8 volts.
Sampling will also cease if the case temperature exceeds 50 C.
As the percentage of memory used approaches 100% you should cease
sampling soon as possible and transfer your results to a PC. There is some
leeway here, for the memory is only truly full when the indicator shows
120%. Sampling will cease automatically and the display will indicate
“DUSTMATE paused” if the end of the memory is reached.
The battery charger should be connected to the 8 pin DIN connector on
the battery pack. When the battery charger is connected, the battery
voltage will eventually rise to about 7.25 volts. The battery pack can be
charged without the instrument.

DUSTMATE EDITOR
The DUSTMATE Editor allows some of the instrument settings and parameters to be
changed. To select the editor press [EDIT] while the display shows "DUSTMATE
ready" or during dust sampling, then use [NEXT] to select what to edit followed by
[ENTER] to select. Note that during dust sampling the number of items which can
be edited is restricted.
When your instrument is connected to your PC, the settings and parameters can also
be changed via the AirQ Configuration Window. Please refer to the next section for
details.
Set Dust Alarm: allows you to set the dust concentration at which the alarm will
operate. Only available when the alarm is enabled. The alarm operates
on the average reading on the Total Particles (Inhalable) channel during
the display interval and is expressed as a percentage of the instrument’s
alarm scale.
On the microgram range the alarm scale is 1000 micrograms, so a
01.00% alarm (default) corresponds to 10 micrograms per cubic meter
dust concentration.
On the milligram range the alarm scale is 10 milligrams, so a 01.00% alarm
corresponds to 0.1 milligrams per cubic meter dust concentration.
The default alarm setting is 01.00% of scale. Press []or []to change
the flashing digit then [NEXT] to move on to the next digit position. Press
[ENTER] to quit and save the revised entry. Press [RESET] to quit without
saving. Press [START] to reset the calibration factor to 1.00.
Zeroing Interval: allows the user to select the time intervals when autozeros
will carried out. The range is 0 hour to 240 hours. The instrument
automatically zero itself when starting to sample and thereafter "on-the-
hour" at the interval shown on the LCD. If the interval is set to 0 hours, no
further zeroes are carried out. Autozeros last for about 5 seconds during

which time the pump is switched off. The default interval is 1 hour. The
previous reading is held during autozeros.
Press (and hold to speed up) []or []to change the interval then press
[ENTER] to save the revised value.
Results Display: allows the user to select which results will be displayed on the
LCD during sampling. The selection can be changed during sampling. The
available options are:
Backlighting: select YES to turn on the display backlight for viewing in
poor light. The extra power used will reduce the total sampling time on
internal batteries by about 30%. Note backlighting can also be controlled
via AirQ.
Display Cycling: select YES if you want the display to automatically
scan around the available results channels. If you select NO then, during
sampling, the results channel shown on the LCD can be changed manually
using [NEXT].
Latest Dust: select YES if you want the display to show the latest particle
concentration. This will be the time weighted average over the Display
Refresh interval.
Average Dust: select YES if you want the display to show the average
particle concentration since the sampling started. Note that average results
are only available after the first results have been saved in memory (i.e.
after the storage interval).
Display Refresh: allows the user to select the time interval at which results display
is updated. The range is 1 second to 240 seconds. The value displayed on
the LCD will be the average reading taken over this interval. Press (and
hold to speed up) []or []to change the interval then press [ENTER] to
save the revised value.

Filter & AirFlow: pressing [ENTER] shows the time and date the filter was last
changed, and the sampling time in minutes it has been used up to a
maximum of 65536 minutes (45.5 days).
Press [RESET] to display the total mass of dust the instrument (based
on its current calibration factor and a flowrate of 600ml/min) thinks it
has accumulated (over all samples) on its filter. This is a useful aid
to calibration.
Press [RESET] to display the total operating time of the pump in hours.
Press [RESET] again and you are prompted to change the filter, press
[ENTER] followed by the password [START] [START] [START] to do
so. The filter timer and filter mass accumulator (but not the pump time
accumulator) will be automatically reset at this time.
If you do not wish to change the filter, just press [RESET].
You will then be prompted to set the sample airflow to its correct value.
Connect a 4 mm OD plastic tube and flow meter to the inlet Luer fitting
on top of the instrument. The correct sample flow during is 600 cc/min.
Use [] or [] to change then [ENTER] to save the new value.
Adjust Clock: allows the time to be changed to compensate for daylight saving. On
selection, the minutes value will flash to indicate it can be adjusted, use
[]or []to change then [ENTER] to save the new value, the hours value
will then flash and can be adjusted likewise. The date can only be changed
at the factory.
The time and date are set by AirQ to the PC time when on-line
sampling starts.
Autostop Counter: allows the duration of the sample to be set. If set to zero, the
instrument will sample until stopped manually. The instrument will cease
sampling after the indicated number of saves to memory (i.e. the sample
