In the settings the user has to define for each channel (1) the
Sensor Settings
and (2) also the environmental
Conditions in the
Sample
under investigation.
Each oxygen channel of the
FireStingO2
meter has its own tab in
the
FireSting Settings
window. By clicking on
Copy these
Settings
, all settings adjusted in the active channel tab can be
pasted to all other channels.
The channels can be activated independently by clicking on the
button
Activate
.
Activation is indicated by a change from dark to
light green of the arrow in the button. A text describing the
connected sensor type appears on the right-hand side of this
button after the
Sensor Code
(see label on sensor) has been
entered. This description will be shown in the description display
(
DD
) of the main window and also in the data file.
Please take care that the sensor code attached to the sensor of a
specific channel of the
FireStingO2
is entered into the field
Sensor
Code
in the same channel panel in the window
Settings
. It includes
information for optimal sensor settings and for calibration data
needed for the factory and 1-point calibration. The first letter of
the sensor code defines the sensor type. A detailed explanation of
the sensor code is given in chapter 12.8.
The oxygen units can be selected for each channel by the selector
Units
. The selectable units include raw value (default), %air
saturation, %O
2
, mL L
-1
, µmol L
-1
, mg L
-1
(ppm), hPa (mbar), mmHg
(Torr), dphi and µg L
-1
(ppb). For measurements in a
Gas Phase
only the units raw value, %O
2
, hPa (mbar), mmHg (Torr) and dphi
can be selected, whereas for measurements of dissolved oxygen in
a
Water
sample (
DO
) all units except %O
2
can be selected. For
detailed information please refer to chapter 12.6.
