Sensor Reference Point
3.5.4.1.
The range in front of the device (referenced from the flange face) within
which any echoes will be ignored. (This is sometimes referred to as
Blanking or Dead Zone.)
Values
The default setting of 0.6 m avoids a false echo being triggered by
condensation or other material buildup. If no buildup is anticipated (for
example, with dry cement) then the minimum setting 0.35 m can be used.
3.5.4.2.
Note:
Maximum distance from the reference point, within which an echo should
be considered valid.
