Internal UV Ozone Photometer
Page 9-9
The other columns of information are described below:
Last Ozone
The Last Ozone is the unaveraged or
"raw" Photometer measurement for each
Photometer cycle.
Noise
The noise column presents the standard
deviation of the raw ozone values during
the rolling average period. This is a
good
indicator
of
how
noisy
the
photometer measurements are.
Average Ozone
The Average Ozone presents the average
of the last
N
raw ozone readings, where
N
is the Rolling Average duration as set
in the Photometer Parameters screen.
This is the value displayed on the Ozone
Calibration Status screen as "Measured
Ozone".
Audit 1
The Audit 1 column of numbers presents
the voltage (between 0.000 and 5.000
Volts) that is measured on the first
Audit analog input. An external ozone
standard or other analog device may be
connected to the Audit 1 input, which is
found on Audit connector pins J7-6(+)
and J7-19(-). A complete wiring list of
the Audit connector can be found in the
Installation
section
of
the
2010D
manual.
PID In
This is the filtered input to the PID
control loop processor. It is derived
by filtering the raw ozone values
obtained from the Photometer.
PID Out
The PID Out column of values represents
the output of the PID loop processor.
This value is used to set the ozone
generator's lamp current in order to
adjust for deviations measured by the
photometer.
