P44 = Slope. Change to 0. This is the gain level parameter, changing it to zero
ensure that there is no gain applied anywhere on the echo profile. Thus reducing
the chance of larger multiples.
P47 = Outside Count. Change to 25. This is the parameter that controls the
movement of the gate. Increasing the value make the movement of the gate to
another echo that is further away less likely.
P49 = Scale First. Change to 50%. This parameter increases the amount of
‘weighting’ the unit will apply to the first echo increasing it makes the echo less
likely to go to a multiple.
P108 = Far End Blanking. Change to 5%. Reducing this value shortens the
effective range of the instrument giving less room for a multiple to appear within
the measured distance (+ far end blanking).
P871 = Empty Damping . Set the value to just above the max rate of emptying.
If the unit does decide to go to a multiple it will do so at the damping rate thus
giving the unit time to recover the true echo before the unit shows a large reading
change.
