80x, 200x or 400x. Note, that varying the LED Intensity and the
Amplification has direct influence on the signal intensity and
therefore on the signal-to-noise-ratio.
The
Oxygen Measuring Time
(default: 10 ms) defines the
integration time for the acquisition of a single data point. Shorter
measuring times provide low long-term drift, whereby longer
measuring times assure less noise. The maximal possible value is
250 ms.
NOTE:
If using the
Advanced Sensor Settings
, it is recommended
to perform a
2-Point
calibration of the oxygen sensor. Later re-
adjustments in the
Advanced Settings
might require also a
recalibration of the sensor.
6.2.3
Conditions in the Sample
The next step is the determination of the
Conditions in the
Sample
, which can be
Water
for dissolved oxygen
(DO)
or a
Gas
Phase
.
Further, it needs to be selected if
during the measurements the
temperature will be determined by
the
External Temperature Sensor
connected to the
FireStingO2
, by
the
Internal Temperature Sensor
of the
FireStingO2
(only possible
for measurements in a Gas Phase!)
or if measurements are performed
at a
Fixed Temperature
(see
chapter 10).
If
External Temperature Sensor
or
Internal Temperature Sensor
(in a Gas Phase) is selected, automatic temperature compensation
