Frequency Range
With selection problems in particular, you could also adjust the frequency settings. Normally,
a high frequency reduces the sensitivity against the background radiation. As displayed on the
bar, you can see which one of the frequency ranges has sufficient flame radiation available
with the selected settings and can choose one of these.
You will find more information on the values in the following table:
