110 / 210 Fiber Optic Oxygen Monitor - Instech Laboratories, Inc.

♦ Analysis Wavelength Box. Enter the
analysis wavelength. The analysis
wavelength should be very close to 600 nm.
(When the excited ruthenium complex at the
tip of the oxygen probe fluoresces, it
typically emits energy at ~600 nm.) In the
Bandwidth [box] pixels area, select the
number of pixels around the analysis
wavelength to average.
♦ Data Display for Sensor Measurement.
Choose the data display format and
precision of the data. Under Format select
Decimal or Scientific. Under Precision,
select a value to specify the precision of the
oxygen data displayed and saved in files.
The maximum is 5.
♦ Wavelength Calibration Coefficients
♦ Do not forget to enter these the first time
using the system.
Check the Wavelength Calibration Data Sheet
that came with your system to make sure the
values on the Data Sheet and in this dialog box
are the same. If not, enter the coefficients
otherwise spectral data may be skewed.
♦ Pressure Compensation CH. If you have
your own external pressure measuring
system, you can use this feature to monitor
and correct for pressure fluctuations in your
sample. You can either use a pressure
transducer separately from the system or
interface it to your sensor system. If you
interface a pressure transducer to your
sensor system, you must have an available
spectrometer channel that is not connected
to an oxygen sensor. Use the pull down
menu to select how you want to monitor
pressure. See Spectrometer DB-25
connector details for attaching the analog
signal to an unused A/D input channel.
♦ Temperature Measurement. If you want to
monitor and correct for temperature
fluctuations in your sample, select a method
from the pull down menu.
-- Select None if you are not monitoring
temperature. For now, this is the
recommended setting.
-- Select Manual if you are monitoring
temperature, but you do not want
OOISensors Software to read and
display the temperature values. The
Manual selection means that you must
manually type temperature values in the
display window. Enable the
Compensate function if you want the
software to correct for temperature
fluctuations only if you calculated the
temperature coefficients. Enabling the
Chart function allows you to view a
chart of the temperature values.
-- Select Omega D5xx1 RS232 if you are
monitoring temperature and if you want
the software to automatically read and
display the temperature values. Ocean
Optics offers the Omega Thermistor and
the Omega Thermocouple for
monitoring temperature. The thermistor
and thermocouple should already be
connected to your PC via an RS-232
module. Next to Serial Port, select the
COM Port number on your PC to which
the thermistor or thermocouple is
connected. Because the RS-232 module
can support up to four thermistors or
thermocouples, it has these four ports
labeled. Next to D5xx1 CH, select the
port to which the thermistor or
thermocouple connects to the RS-232
module. (If you only have one
thermistor or thermocouple, select 0.)
Enable the Compensate function if you
want the software to correct for
temperature fluctuations. Enabling the
Chart function allows you to view a
chart of the temperature values.
♦ Enable reference correction. Disable this
function.
♦ Level alarm. Enable this feature to set
alarm properties. A green indicator appears
in the display window if this feature is
activated. If the values fall below the alarm
parameters, the green indicator turns red. If
the values rise above the alarm parameters,
the green indicator turns yellow.
