Internal UV Ozone Photometer
Page 9-10
The "Detailed" Photometer diagnostics presents more detailed
information about the photometer. Rather than updating each
photometer cycle, it presents new information each half-cycle,
allowing the reference and sample data to be observed. Figure 9-
shows an example of the Detailed Photometer Diagnostics screen.
Figure 9-5 The Photometer Diagnostics Screen, Detailed
Many items found in the detailed screen are the same as the
general screen, however there are a few additional items. They
are:
Ref.
This is the detector reading during the
reference half of the Photometer cycle,
after being converted to a unit-less
number or "count".
Sample
This is the detector count during the
sample half of the Photometer cycle.
The ratio of the reference count to the
sample count is used to calculate the
ozone concentration as described on Page
2.
Sample Pressure (mmHg)
This is the pressure in the measurement
tube as measured by the Photometer's
pressure sensor.
