Use the following procedure to perform an ambient pressure calibration.
1.
Press
to return to the Calibration menu, scroll to Ambient Pres
and press
.
2.
Determine the current ambient station pressure in mmHg (absolute
pressure, not corrected to sea level).
To convert from Atmospheres @ 0 °C to mmHg, multiply by 760.
To convert from millibars to mmHg, multiply by 0.75012.
To convert from inches Hg @ 32 °F to mmHg, multiply by 25.4.
3.
Enter the measured ambient pressure and press
. The Sampler
automatically adjusts the corresponding offset based on this input.
Use the following procedure to perform a Filter Pressure calibration and a
Filter2 Pressure calibration.
1.
Press
to return to the Calibration menu, scroll to Filter Pres and
press
.
2.
Determine the current ambient station pressure in mmHg (absolute
pressure, not corrected to sea level).
To convert from Atmospheres @ 0 °C to mmHg, multiply by 760.
To convert from millibars to mmHg, multiply by 0.75012.
To convert from inches Hg @ 32 °F to mmHg, multiply by 25.4.
3.
Enter the measured ambient pressure and press
. The Sampler
automatically adjusts the corresponding offset based upon this input.
4.
If the Sampler is a Partisol 2000
i
-D, repeat these steps to calibrate the
filter2 pressure sensor.
