Mul plier
Sets the conversion Mul plier that will be applied to the sensor readings. The
default is 1.000 (see note below) and typically does not need to be adjusted.
However, since the speed of sound is not constant through all environments,
the mul plier parameter allows the user to adjust for varia ons in atmosphere
when maximum accuracy is required.
Temperature Compensa on (0 = Off , 1 = On)
Used to enable or disable the internal temperature compensa on of the sen-
sor. Enabling the internal temperature compensa on can reduce the eff ects of
temperature changes by 50% or more, depending on the temperature gradient
through the sensing range.
Off set
Used to adjust the zero reference point of the sensor. When the Off set is set to
0, the zero reference of the sensor is at the face of the transducer. Se ng the
Off set to a nega ve number will move the zero reference backward (behind the
sensor face), while a posi ve se ng will move the reference forward (in front
of the sensor face).
Maximum Distance
Sets the distance (beginning from the sensor face) to the point where the sen-
sor will stop looking for target signals. Targets detected beyond the Maximum
Distance value will be ignored by the sensor.
