For the span calibration gas, clean dry instrument air with oxygen content of 20.9 % is
recommended.
Before starting to calibrate the analyzer, check the settings of zero and span gas used in
the Calibration Menu.
If the value of zero gas used is not correct, select Zero gas used and enter the value
of the zero gas used.
If the value of span gas used is not correct, select Span gas used, and enter the value
of the span gas used.

To calibrate the oxygen signal, do the following steps:
Introduce zero calibration gas to the sensor, and wait for the zero-value reading to
stabilize, e.g. 1.8 %. Then enter Calibration Menu and select Zero calibration. The
zero calibration is completed when the analyzer returns to the Main Menu. The new
calibration value will be displayed after 15 seconds (as per default setting of freeze
output).
Introduce the span calibration gas to the sensor, and wait for the span value reading
to stabilize, e.g. 21.1 %. Enter Calibration Menu and select Span calibration. The
