Figure 5 Diameter of sensitive beam at the half-section length (ERMO 482X3
PRO
/ 250-500)
Remark:
that for the ERMO 482X3 PRO equipment, the sensitivity regulation to be considered to
obtaining the dimensions of the sensitivity beam at half- section length, is that of the
pre-alarm threshold.
The higher the pre-alarm threshold the lower the sensitivity,
and vice versa.
It’s important to keep in mind that the
pre-alarm threshold
determines
the beginning
of the intelligent analysis:
all signals below this threshold, are considered noise, and
anyway of low importance. All the signals higher this threshold are analyzed following
Fuzzy rules.
The prealarm and alarm thresholds, are settable both with software WAVE-TEST2 and
with rotary switches on board on each receiver. Default setting corresponds to a
medium sensitivity fightable for most of the cases.
