4.1.2 Standardization of flame signal display AZL5

The flame signal display on the AZL5 can be standardized; this means that a display
value of 100% can be assigned to any flame signal.
This function is used for plants where the maximum flame signal has not reached a
display of 100% in order to increase the display to 100% by means of standardization.
The actual flame signal remains unchanged!
As soon as the flame signal to be standardized is stable, standardization can be
performed by selecting and confirming the following options in the AZL5menu:
Params & Display  BurnerControl  Configuration  ConfigFlameDet 
FlameSignal  Standardize.
During standardization, a standardization factor StandardFactor is determined, which
can be displayed and reset.
Parameter StandardFactor
The accuracy of the display is a maximum of °10%, depending on the tolerances of the
components.
It should also be noted that, for physical reasons, there is no linear relationship
between the display and the detector signal values. This is especially obvious with
ionization current supervision.
For more detailed information, refer to Data Sheet N7714.
