Quick Start: local
1.2. Material
Selects the appropriate echo processing algorithms for the material (see Position
Detect (2.8.4.2.) on page 127 for more detail).
1.3. Response Rate
Sets the reaction speed of the device to measurement changes in the target range.
Use a setting just faster than the maximum filling or emptying rate (whichever is
greater).
1.4. Units
Sensor measurement units.
