20 mA calibration

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.
