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).

Speed of Response

The speed of response adjustment allows the user to collectively set a number of operating
parameters.

is the limit to which The Probe will be able to keep up with rates of change.
If The Probe measurement cannot keep up with the rate of level change, set the
adjustment from `1' to `2'. If The Probe still cannot keep up with the rate of level
change, set the adjustment option to `3'. Avoid choosing an option that is too fast for
your application.

discriminates between false echoes from acoustical and electrical noise and the

establishes the `Waiting' period from the time a loss of echo or operating fault
condition starts until the fail-safe default is effected. Adjusting the speed of
response will set the fail-safe timer to the default values in the chart. If a different
response is required, adjust the 'FSt' option (see page 13).
