OXYGEN ANALYZER CALIBRATION
PRESSURE ANALYZER CALIBRATION
CALIBRATION
� To calibrate the oxygen analyzer you have to place the
instrument outside in fresh air where the oxygen
concentration is 21%, or use an oxygen calibration
standard.
Go to the calibration locality CALIB.lc (Window W.26)
and let the instrument measure two or three points to
allow it to stabilize itself.
� Measure one station in the fresh air without any tubing
connected. After measuring go to the Main Menu,
select CALIBRATION and continue the calibration
procedure as described for the calibration of the PID
analyzer. In window W.31 activate O2 and type in “21”
if the instrument was calibrated with fresh ambient air,
or type in the real value of the O2 calibration standard
used .
� Go to Calibrate and complete the calibration according
to the described procedure.
� No tubing must be connected to the instrument inlet.
Just start measuring – you do not need any standard
since you measure only atmospheric pressure.
� Open the calibration locality CALIB.lc and let the
instrument measure two or three points to allow it to
stabilize itself.
� After measuring, go to the Main Menu (Window W.2),
select CALIBRATION and continue the calibration
procedure as was described for the calibration of the
PID analyzer.
� In the window W.32 activate the pressure channel. To
continue the calibration you have to know the
atmospheric pressure from the nearest meteorological
station. Meteorological services usually provide the
latest values of atmospheric pressure on their web
sites. If you need to calibrate pressure precisely, you
have to recalculate the pressure value for your actual
altitude.
� Type in the obtained value from the meteorological
station as the actual value of atmospheric pressure.
� Go to Calibrate! and complete the calibration according
to the described procedure.

W.31 - Selection of analyzer for oxygen calibration.
Note: For calibrating the oxygen analyzer it is also possible to use a two-point calibration procedure
implemented in ECOPROBE_VIEW software. This calibration may also use a standard with zero
concentration of oxygen (nitrogen). In this way a more reliable calibration and compensation for the decay of
the oxygen sensor are obtained.

W.32 - Selection of analyzer for pressure
calibration.
The calibration constant for temperature, pressure and oxygen may vary in tenths or hundreds of
units.
Another method to calibrate oxygen and pressure analyzers and the probe thermometer is to use
the ECOPROBE_VIEW software. The procedure is described in the manual.
