Code is identical to the one written on the label attached to the
sensor cable or on the bag/stickers of the sensor.

Air Calibration
C
lick on the button Calibrate Air
to open the Air Calibration
window.
This
will
also
automatically open the Live
Graph window (see 10.3.1).
(1) Choose Calibration Medium.
Specify the Medium of the
calibration standard
. If the
measurements will be done in
the gas phase, it is advised to choose Ambient Air and to continue
with step (2A). If the measurements will be done in aqueous
samples, it is advised to choose Air Saturated Water and to
continue with step (2B).
(2A) Calibration in Ambient Air. Ambient air serves as a simple
standard (ca. 20.95%O2 in dry air). In order to determine the
precise oxygen partial pressure in ambient air, the atmospheric
pressure and the relative humidity will be read automatically from
the internal air sensor (chapter 3.1.4).
Ensure that both the
FireStingGO
2
device and the connected
sensors are exposed to identical environmental conditions.
Position the sensor tips in close proximity to the
FireStingGO2
device.
Ensure that the oxygen and the temperature sensor are completely
dry; otherwise the relative humidity around the sensors will differ
from the measured humidity inside the
FireStingGO2
.
