The voltage range of each output is independently selectable by
installing jumpers labeled JP1 through JP8 on the detector preamp
board, near the rear panel (see Figure 9-2). All outputs are set
to the 10V range by default, with all jumpers installed (oriented
vertically). Other ranges can be selected by removing jumpers,
as shown in the table, below:
Output 1 JP1 JP2
Output 2 JP3 JP4
Output 3 JP5 JP6
Output 4 JP7 JP8 Range

Operation
There are three basic modes of operation for the Model 2010
D
's
UV Ozone Photometer. These are:
Audit Mode
In Audit Mode, the Photometer is used to
measure the ozone output of the Model
2010D
and serves as an independent audit
device.
Ozone Servo Mode
In this mode, the Photometer's
measurement is used to automatically
adjust
the 2010
D
's internal ozone
generator. This results in a precise
ozone concentration that is independent
of temperature, pressure, humidity and
other factors that can affect ozone
production.
Continuous Mode
Ordinarily, the Photometer is activated
only during ozone calibrations. In
Continuous Mode, however, the Photometer
will remain active continuously while
power is applied to the
2010D
This
feature allows the 2010
D
's Photometer to
be operated independent of the 2010
D
's
other functions as a stand-alone ozone
monitor.
