the SETTING mode and aer calculations are made, these correspond to acceptance, reporting and search levels (Figure 23).
When the amplitude of the signal exceeds the reporting /search level of the DGS curve and the signal is in the strobe
interval, AFAS will be actuated.
The displayed value of the signal amplitude (considering the sign) will be indicated with reference to the acceptance level, namely:
- “plus” sign means the signal exceeds the acceptance level by the given value;
- “minus” sign means the signal is below the acceptance level by the given value.If parameters for calculation are not
correct, then an information window will appear (Figure 24) and the icon will change to
. If so, check correctness
of the set parameter values.
