Blanking

Blanking is used to ignore the zone in front of

the transducer where false echoes are at a

level that interfere with the processing of the

true echo. It is measured outward from the

sensor face. The minimum recommended

blanking value is 0.25 m (0.82 ft) but can be

increased in order to extend the blanking.

Factory setting: 0.20 m (0.66 ft)

5.4.7

Range limit

The range limit is the distance at which measurements are ignored. Generally this refers to

the bottom of the container being measured. If a measurement is detected beyond the range

limit it results in a Loss Of Echo (LOE) reading. The result of this reading is determined by

the Fail-safe mode, see Fail-safe mode (Page 24) for more information.

Factory setting: 5.50 m (18.0 ft)
