Setting detection sensitivity
The purpose of the detection sensitivity setting is to find the lowest sensitivity
setting that still reliably detects the test objects using the detection program in
question. This way it is possible to reach high throughput rates, because unwanted
alarms caused by harmless objects are minimized.
The sensitivity setting also affects interference immunity of the WTMD. Therefore
it is not recommended to use a higher sensitivity setting than required for the
application.
To adjust detection sensitivity test objects should be taken through the gate
attached to different parts of the body and at various orientations.
The adjustment of detecting sensitivity is
done in two phases. Overall sensitivity is
defined first, either manually or using
automatic sensitivity adjustment, except at
ankle level (1).
In the second phase (2) sensitivity at
ankle level is defined (Zone sensitivities).
Sensitivity is adjusted manually or using
automatic floor sensitivity adjustment.
Ankle level sensitivity (2)
shall always be calibrated
separately, because floor
structures usually contain
metal reinforcements that
may affect the sensitivity
setting.
The amount and orientation of the metal in
the floor in relation to the gate varies
between different installation sites.
Therefore, the required sensitivity setting at
floor level may also vary.
