10 Adaptation of temperature level
By changing the emissivity ratio, the difference between the measured temperature level and
true temperature can be compensated.
For this purpose, a comparison measurement with an immersion lance is required. Adjust
emissivity ratio in such a way that the measured values coincide. An increase in the emissivity
ratio results in a low temperature value.
The graph shows an approximation of the influence of the emissivity ratio setting on the change
in temperature value.
