Fibox 3 LCD trace 3 Preface
1 Preface
You have chosen a new, innovative technology for measuring oxygen.
The Fibox 3 LCD trace is a compact easy to transport fiber optic oxygen transmitter for stand-
alone or PC controlled use. The data evaluation is PC supported. The Fibox 3 LCD trace was
developed especially for small fiber chemical optical oxygen sensors, flow-through cells and
integrated sensor systems. It is based on a novel technology, which creates very stable,
internally referenced measured values. This allows a more flexible use of oxygen sensors in
various fields of interest.
Optical oxygen sensors (also called optodes) have several important features:
They are small.
Their signal does not depend on the flow rate of the sample.
They can be physically divided from the measuring system which allows a non-
invasive measurement.
They can be used in disposables.
Therefore, they are ideally suited for the examination of small sample volumes, for highly
parallelized measurements in disposables, and for biotechnological applications.
A set of different oxygen minisensors, flow-through cells and integrated sensor systems is
available to make sure you have the sensor which matches your application.
Please feel free to contact our service team to find the best solution for your application.

4.3 Measurement
After sensor type selection and calibration the measurement parameters can be set.
Select MENU / Measurement; you can set the following parameters:
Sampling rate
Select the measurement point frequency. Sampling rates from fastest to 60 min can be set.
For the PSt3 sensor the fastest sampling rate is 1 second, for PSt6 it is 3 seconds. In
addition, any other sampling rate between 1 and 3,600 seconds can be chosen by selecting
other. Change the settings with the und keys and press ENTER.
Temperature
Select the temperature measurement mode for temperature compensated oxygen
measurement:
PT1000
With this setting the temperature value necessary for the temperature compensation
of the oxygen sensor is measured with the supplied PT 1000 temperature sensor.
Manual
With this setting a constant temperature value is set manually for temperature
compensated oxygen measurement. This option can be used, if the temperature at the
location of the oxygen sensor is known and stays constant during measurement.
Change the temperature value by using the “+“ and “-“ keys and press SET.
External
With this setting an external analog signal is transferred to the transmitter via one of
the analog connectors on the transmitter rear panel.
To use this option the settings in the submenu Configuration / Analog In / Channel 1
or Channel 2 have to be adjusted first. Please read more detailed information on
analog input in chapter 4.5 „Configuration“.
When the pre-settings in the submenu Analog In are completed the respective
channel can be selected in External. Now the analog input signal is captured, digitally
converted and used for correct temperature compensated measurement and oxygen
value calculation.
Sensor protec.
Select a maximum temperature for deactivating the measurement function. Setting a
temperature limit is supposed to protect the sensor. With increasing temperatures (e. g. in
autoclave or CIP cleaning processes) the optical excitation can cause accelerated sensor
aging. The sensor illumination will be turned off when the measured temperature (PT 1000,
Manual, External) reaches the selected maximum value. The message “Warning! Sensor
protection” is displayed.
The selection range is 20°C to 100°C. Change the temperature value by using the “+“ and “-“
keys and press SET. The default value is set to 40 °C.

Signal average
This function is for more experienced users. You can select automatic or manual internal
averaging of data points per measurement point. Depending on the signal amplitude of the
sensor the illumination time per measurement point can be adjusted. With a higher
illumination level the signal-to-noise ratio can be improved, with a lower illumination level
sensor bleaching can be avoided and its measurement stability prolonged.
There are two options. With AUTO the pulse length in illumination gets adjusted automatically
by the device, with Manual the pulse length can be selected in a range from 1 to 4. With
higher selected value the illumination time increases and more single measurement points
are used for averaging one measurement point. Change the setting by using the “+“ and “-“
keys and press SET.
Oxygen unit
Select the desired oxygen unit. Change the setting with the and keys and press ENTER.
These options are available:
% air sat.
% oxy. sat.
hPa
Torr
ppm (ppb)
µmol/l
Sig. intensity
This function is for more experienced users to change the illumination level of the device.
With a higher illumination level the signal-to-noise ratio can be improved, with a lower
illumination level sensor bleaching can be avoided and its measurement stability prolonged.
! A change in signal intensity will invalidate the calibration values of the sensor and it
has to be recalibrated. The display also shows the warning message “This can
change calibration values“.
The selection range is 5 % to 100 %. Change the setting by using the “+“ and “-“ keys and
press SET.
Submenus can be selected using the and keys and pressing EDIT switches to editing
mode. When all required settings are done, go back to the main view on the display by

4.5 Configuration
Select MENU / Configuration. Submenus can be selected using the and keys and
pressing EDIT switches to editing mode.
The following configurations can be adjusted:
Status
Status displays the current device parameters like illumination level (Sig.intensity), internal
referencing (Ref. current, Ref. amplitude), internal measurement averaging (Sig. average)
and the temperature compensation mode (Temp. comp.). Press any key to leave this menu.
Analog out
In the Analog out menu parameters for the analog output can be selected.
There are four analog out channels available (two voltage and two current channels, Voltage
U1, Voltage U2, Current I1, Current I2).
The following parameters can be selected for each channel:
Inactive (no analog output)
Oxygen
Temperature
Phase
Amplitude
The additional submenu 20mA/10V value allows setting a conversion rate for maximum
possible analog output. Depending on the selected oxygen unit the maximum oxygen value
corresponding to the maximum output of 20 mA or 10 V can be set.
For example, 10 V can be set to 100 % air-saturation, then 1 V corresponds to 10% air-
saturation; or 10 V can be set to 200 ppm gaseous oxygen, then 1 V corresponds to 20 ppm.
Analog in
The transmitter has two analog in channels which allow feeding an external analog signal to
the device. A temperature value measured by an external device can be transferred to the
transmitter as voltage in a range from 0 to 10 V.
In the submenus Channel U1/Variable and Channel U2/Variable you can choose between
the options Inactive and Temperature. The submenu /Range allows assigning a lowest
temperature value to the voltage of 0 V (Low value) and a highest temperature value to the
voltage of 10 V (High value). This equals a two point calibration for the external voltage. The
assignment of “Low value” and “High value” is only possible, if the variable Temperature is
selected.
For example: If the input signal of 10 V corresponds to temperature of 60°C, you should set
the value in the High value control window to 60; and if the input signal of 0 V corresponds to
temperature of 10°C, you should set the value in the Low value control window to 10.
With an input voltage of 5 V the imported temperature will be 35 °C in this case, or with an
input voltage of 7.5 V it will be 47.5 °C.

electric signals. This can be done by entering the submenu Diag&Test / Analog In.
The input voltage can be controlled directly on the LCD panel.
Clock/Date
This menu allows changing the current date and time settings. Change between positions by
pressing Next and adjust the setting using the “+” key. Save the changes with SET or cancel
the process by pressing Back.
Display
There are three different settings for background illumination:
OFF background illumination is turned off
ON background illumination is permanently turned on
AUTO background illumination is activated by pressing any key and turns back off
after 10 sec., if no other key is pressed.
Change the setting with the and keys and press ENTER or cancel the process by
pressing BACK.

5.5 Calibration
Click the Calibration tab in the upper middle screen.
Fig. 30 Calibration tab
There are three different calibration modes:
With the setting with temperature sensor the current raw phase values of the oxygen
sensor are measured and stored. Temperature during calibration is measured and
saved with the current temperature measurement settings (PT 1000, External). The
temperature sensor has to be in close vicinity to the oxygen sensor or make sure that
the temperature at both oxygen and temperature sensor is the same.
With the setting without temperature sensor the current raw phase values of the
oxygen sensor are measured and stored. The temperature value during calibration is
set manually in the software and stored. This option can be used, if the temperature
at the location of the oxygen sensor is known.
With the setting manually the raw phase values of the oxygen sensor as well as the
temperature values are set manually in the software. This option can be used, if
previously measured calibration values for the currently used oxygen sensor are
available. You can find calibration data on the Final Inspection Protocol delivered with
your oxygen sensor.
