Parameters
2.3.2. High Calibration Pt.
Distance from sensor reference point
1)
to High Calibration Point. Units are
defined in Units (2.2.1.).
When setting the High Calibration Point value, note that echoes are ignored
within Near Range (2.2.1.11).
2.3.3. Sensor Offset
A constant offset that can be added to or subtracted from sensor value
1)
to
compensate if the sensor reference point has shifted. (For example, this could
result from adding a thicker gasket or reducing the standoff/nozzle height.)
2.4. Rate
2.4.1. Response Rate
Sets the reaction speed of the device to measurement changes.
Use a setting just faster than the maximum filling or emptying rate (whichever
is faster).
Values
Range: 0 to 20 m. Default 0.00 m
Related parameters
Units (2.2.1.)
Near Range (2.8.1.)
1)
The value produced by the echo processing which represents the distance from sen-
sor reference point to the target. (see Sensor Mode (2.2.2.) on page 79 for an illustra-
tion).
Values
Range: -99.999 to 99.999. Default: 0.00 m

Note: Changing Response Rate resets Fill Rate (2.4.2.), Empty rate (2.4.3.), and
Damping Filter (2.2.4.).
