Mul! plier (0 to 1999) (40416)
Sets the conversion Mul! plier that will be applied to the sensor readings. The
default is 1000 (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.
NOTE: the decimal place for the Mul! plier is always assumed to be in the
thousands posi! on, therefore a se" ng of 1025 = 1.025 actual mul! plier.
Off set (-10364 to 10364 mm) (40417)
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).
Temperature Compensa! on (0 = Off , 1 = On) (40420)
Used to enable or disable the internal temperature compensa! on of the sensor.
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.
Parameter Data (0 to 100,000 mm) (40436 to 40445)
The Parameter Data registers are used to enter tank dimension or conversion
mul! pliers for all the volumetric Applica! on Types (types 2-10).
