4 mA calibration
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.
• To change the stored blanking value, obtain the `bL' display.
• Press the "20" key to increase or the "4" key to decrease the blanking value.
• When the display has scrolled to the desired value, stop pressing the key. The display
automatically returns to the Run mode (6 sec).
