MULTIP (Multiplier):

Sets the conversion Multiplier 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 multiplier parameter allows the user to adjust for variations in atmosphere

when maximum accuracy is required.

NOTE: the decimal place for the Multiplier is always assumed to be in the

thousands position, therefore a setting of 1025 = 1.025 actual multiplier.

OFFSET (Offset):

Used to adjust the zero reference point of the sensor. When the Offset is set to

0, the zero reference of the sensor is at the face of the transducer. Setting the

Offset to a negative number will move the zero reference backward (behind the

sensor face), while a positive setting will move the reference forward (in front

of the sensor face).

T-COMP (Temperature Compensation):

Used to enable or disable the internal temperature compensation of the sen-

sor. Enabling the internal temperature compensation can reduce the effects of

temperature changes by 50% or more, depending on the temperature gradient

through the sensing range.
