Operation
4. Click the Set DUSTTRAK Calibration button. The following dialog box
is displayed.
5. Enter a new Calibration Factor along with a new Name and press
Add. This adds the new Calibration Factor to the list of available
factors. In the example above, the “Wood Dust” factor, with a value of
1.45, was added to the list.
Note: This step does not automatically download the new value to
the D
USTTRAK monitor. This must be done in a separate step.
6. Highlight the desired Defined Calibration factor (either the new one or
a previous factor) by clicking on it, and press Send. This downloads the
new Calibration Factor to the D
USTTRAK monitor. You can enter up to
25 different custom calibrations.
7. The D
USTTRAK monitor response for all subsequent measurements will
be multiplied by the new factor. To reset the D
USTTRAK monitor to
factory calibration, simply send the factory setting of 1.
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 T
RAKPRO 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, follow these
steps:
Note: This process converts existing data files using a new calibration
factor. It does not affect the current reading of the D
USTTRAK
monitor. Future measurements will continue to be read and logged
with the original calibration factor (normally 1.0) and will not be
converted automatically.
1. Connect your D
USTTRAK monitor to the computer and start the
T
RAKPRO software.
