Assuming the instrument cover has been removed, the heater has been
turned off and removed from the instrument and the instrument has been
sampling room temperature air for 1-hour, this calibration can now
proceed.
Using a NIST-traceable thermometer as a reference collocated next to the
small sample tube inlet on top of the instrument, measure and compare
three individual readings between both the reference and the 5030
i
response. Taking an average of both sets of readings, calculate the average
difference between the two readings and record that as your offset. This
offset (ZERO) should now be entered in the screen below:

Be sure to save the entry and compare the values once more. If it appears
that the temperature has shifted into the wrong direction, change the sign
of your offset value.
There are three pressure sensors that can be calibrated, however, the
primary sensor to be calibrated is the barometric pressure sensor. Both the
vacuum sensor and pressure flow sensors are re-zeroed automatically with
every filter tape change.
Using a NIST-traceable barometer, measure the barometric pressure (and
convert as necessary) in units of millimetres of mercury (mmHg). Use the
SPAN feature from the barometric calibration submenu.
