Manual Background Compensation
The calibration of contactless sensors (i.e. sensor spots, flow-
through cells and respiration vials) includes a compensation of
potential background fluorescence from the fiber-optic cable
connecting the
FireStingO2
with the contactless oxygen sensor.
Based on the
Fiber Length (m)
entered in the
Settings
(see
chapters 6.2.1 and 6.2.2), a background signal for compensation is
estimated automatically by the
Pyro Oxygen Logger
software. So
the user usually does not notice the background compensation at
all. For normal applications this should be the preferred procedure.
But for precision applications and especially for low signal
intensities (e.g. <20mV), a manual background compensation can
be alternatively performed by the user. For this,
Manual
Background Compensation
must be selected in the
Advanced
Settings
(see chapter 6.2.2). After opening the calibration window
by clicking on
Calibrate
, a separate
Background Compensation
window will be opened automatically:
Here the background fluorescence of the connected
Optical Fiber
can be compensated. For this it is
important
that
