one end of the
Optical Fiber
is connected to the
corresponding channel of the
FireStingO2
and
the other end of the
Optical Fiber
is
not
attached to the
sensor spot (i.e. disconnect this end from the spot adapter,
adapter ring or from the flow-through cell)
Then wait for steady state and press the button
Take Actual
Values
.
Alternatively, the button
Keep Last Values
can be used if the
sensor spots are (re-)calibrated with the
same
optical fiber, which
was background compensated before. Then the last values for the
background compensation are kept.
It is also possible to enter values for the
Background
and
dphi
(°)
manually into the field
Manual
and subsequently clicking on
Take
Manual Values.
If you enter manually zero for
Background
, no
background compensation is performed.
After the background compensation is finished, the window closes
and the program proceeds with the main calibration window (see
chapter 7). It is important that for the subsequent calibration
process the
Optical Fiber
is again attached to the sensor spot
position, e.g. by connecting this optical fiber end again to the spot
adapter, adapter ring or to the flow-through cell.
Please ensure that
during the background compensation
the
Optical Fiber
is not connected
to the contactless sensor.
Please ensure that
during the subsequent calibration process
the
Optical Fiber
is again attached to
the contactless sensor.
Remind that the position of the spot adapter or adapter ring
should not be changed after calibration of the sensor spot;
otherwise it has to be re-calibrated.
