Wait for steady state until the sensor reading is stable by observing
the graph. If
External Temperature Sensor
was selected, ensure
also stable temperature readings indicated at
Temperature
Sensor (°C)
. Note that the button
Set Air
will be highlighted as
soon as the oxygen readings are within the expected range for the
connected sensor type (the latter does not apply for a custom air
calibration with ≠20.95 %O2).
If all readings have reached their steady state, click on
Set Air
, and
the actual oxygen sensor reading is taken for the air calibration. If
the oxygen reading seems to be out of the expected range, a
warning will be shown offering the possibility to repeat the
calibration. A completed air calibration is indicated by the green
indicator
Calibrated at Air
.
NOTE
: If using retractable needle-type sensors (e.g.
OXR50
,
OXR230
,
OXR430
), it is important that the sensor tip is extended to
position 2 or 3 (see chapter 5.1) when the calibration value is taken.
Subsequently insert the oxygen sensor and the external
temperature sensor (if used) into the 0% calibration standard. Wait
for steady state until the sensor reading is stable by observing the
graph. If
External Temperature Sensor
was selected, ensure also
stable temperature readings indicated at
Temperature
Sensor (°C)
. Note that the button
Set 0%
will be
highlighted as soon as the oxygen readings are within
the expected range for the connected sensor type.
If all readings have reached their steady state, click on
Set 0%
, and the actual oxygen sensor reading is taken
for the 0% calibration. If the oxygen reading is out of the
expected range, a warning will be shown offering the
possibility to repeat the calibration. A completed 0%
calibration is indicated by the green indicator
Calibrated at 0%
.
