With this function, you set the device to a second dialog language.
The device is always delivered in the ordered language. Usually, English is included as a
second language (if English is the first language, Spanish is set as the second language).

Figure 5-62 Carrying out correction of cross-interference
Flammable gases influence the O
2
measurement in that they reduce the O
2
content of the
sample gas. The sensor temperature, the concentration of flammable components, as well
as the O
2
concentration and sample gas flow all have an effect.
The relationship between interfering gas concentration and O
2
offset is usually non-linear
(see also Table "Examples of typical interfering gas offsets on a catalytically inactive
sensor").
Note
A differentiation must always be made with the correction of cross-interference as to whether
the interfering gas has a constant or variable concentration.
