High Calibration Pt. (2.3.2.)
Distance from sensor reference point
1)
to High Calibration Point. Units are defined in Units
(2.2.1.).
Values
Range: 0 to 20 m. Default 0.00 m

Units (2.2.1.)
Near Range (2.8.1.)
When setting the High Calibration Point value, note that echoes are ignored within Near
Range (2.8.1.).
1)
The value produced by the echo processing which represents the distance from sensor
reference point to the target. [see Threaded Horn Antenna with extension (Page 189),
Flanged Horn with extension (Page 194), and PTFE Flanged encapsulated antenna
(3"/DN80/80A sizes and larger) (Page 200)].
Sensor Offset (2.3.3.)
A constant offset that can be added to or subtracted from the sensor value
1)
to compensate
for a shifted sensor reference point. (For example, when adding a thicker gasket or reducing
the standoff/nozzle height.) The units are defined in
Units (2.2.1.).
Values
Range: -100 to 100 m. Default: 0.00 m
