hPa = atm X 1,013.2501
hPa = in Hg X 33.8638867
hPa = mm Hg X 1.3332239
There are two additional pressure sensors responsible for the differential
orifice measurement (P1) and the sample differential vacuum measurement
(P2) under the filter tape. Both of these pressure sensors are very stable with
the factory calibration and are re-zeroed with every filter change.

Note The air flow calibration always has to be performed last. Subsequent
temperature and pressure sensor calibrations could have an impact on the air
flow calibration.
The automated detector adjustment is completed through a series of serial
commands and can be found on our Air Quality Instruments Online
Library at www.thermoscientific.com/aqilibrary.
This is the sub-menu used for the air flow rate
calibration. The user may toggle the pump
on/off with the PUMP key. Generally it is good
practice to turn the pump off prior to attaching
and removing the flow transfer standard (FTS).
The volumetric flow rate is initially indicated as
measured by the Model 5030. Press CAL to
adjust the air flow rate calibration coefficient.
Thereafter, adjust the volumetric air flow rate
measured by a FTS using the +, - keys and press
NEXT. Allow 30 seconds between indicated air
flow adjustments. Repeat as necessary until
corresponding FTS and Model 5030 flow rate
values agree within 2%.
