4.3.2
1-point calibration (manual)
During the 1-point calibration of the sensor, the calibration offset is determined. Test air is hereby applied to the
sensor. In systems without an integrated pneumatic unit, test gas needs to be applied manually and the flow control
also may need to be checked and adjusted if necessary.
Course of events
(1) Enter System Code
(2) Maintenance LED is lit
(3)
Prompt to apply test air
(only for systems without flow monitoring)
(4) The calibration process is carried out with test air
(5)
Prompt to end the test air application.
(only for systems without flow monitoring)
(6) Display of the return to process if the difference between the measured concentration in the process and
the O
2
concentration with test air is more than 3.00%.
(7) Enter the O
2
concentration of test gas
(does not apply to test air)
(8) Display of the calibration results (max. 1 minute)
(9)
Maintenance LED switches off
(is delayed by the set value in "Delay time to process" if "Meas. Value hold
on cal" is set ON)
(10) Revert to main display
4.3.3
2-point calibration (manual)
During the 2-point calibration of the sensor, the calibration offset and slope is determined. Hereby two gases are
applied to the sensor (test air and test gas. In systems without integrated pneumatic units, test gas needs to be
applied manually and the flow control also may need to be checked and adjusted if necessary.

(7) Prompt to end the test air application.
(only for systems without flow monitoring)
(8) Display of the return to process if the difference between the measured O
2
concentration in the process and
the concentration with test air (test gas 1) is more than 3.00%.
(9) Prompt to enter test gas concentration(s)
(10) Display of the calibration results (max. 1 minute)
