Parameters
2.4.2. Far Range
Allows the material level to drop below Low Calibration Point without
generating a Loss of Echo (LOE) state. See Low Calibration Pt. (2.3.5.1.) on page
67 for an illustration.
Use this feature if the measured surface can drop below Low Calibration Point
in normal operation. See
Far Range (2.4.2.) on page 120 for more detail.
2.4.3. Minimum Sensor Value
Read Only. Defines the minimum usable value for the measuring range, in units
defined in Unit (2.3.1.).
(Default = 0.0 m)
• Open the menu View – Device Diagnostics > Device Status, and click on
the Device Status tab.
• Check Sensor Peak Values.
2.4.4. Maximum Sensor Value
Read Only. Defines the minimum usable value for the measuring range, in units
defined in Unit (2.3.1.).
(Default : 105 m for 100 m device, 45 m for 40 m device)
• Open the menu View – Device Diagnostics > Device Status, and click on
the Device Status tab.
• Check Sensor Peak Values.
Note: Far Range can extend beyond the bottom of the vessel.
Values
Range: Min. = Low Calibration Pt.
Max. = 45 m (131.2 ft): 40 m device
= 105 m (344.5 ft): 100 m device
Default: Value for Low Calibration Pt. + 5 m (16.4 ft)
