H: Parameters
2.5.3. Min. Sensor Value (default 0.25 m)
Defines the minimum usable value for the measuring range (physical limit of the
sensor) in Sensor units.
Open menu View – Peak Values and select the tab AIFB1 or AIFB2. If necessary,
click on the reset button, and download to the device.
2.5.4. Max. Sensor Value (6 m or 12 m, depending on unit)
Defines the maximum usable value for the measuring range (physical limit of the
sensor) in Sensor units.
Open menu View – Peak Values and select the tab AIFB1 or AIFB2. If necessary,
click on the reset button, and download to the device.
2.5.5. Process Temperature Min.
The minimum recorded temperature of the internal electronics.
Open menu View – Peak Values and select the tab Temperature. If necessary,
click on the reset button, and download to the device.
2.5.6. Process Temperature Max.
The maximum recorded temperature of the internal electronics.
Open menu View – Peak Values and select the tab Temperature. If necessary,
click on the Reset button, and download to the device.
2.6. Linearization
Carries out a volume conversion from a level value.
2.6.1. PV (volume/level) Units (default %)
Select units for either volume or level.
2.6.2. Linearization Type/Tank Shape (default None)
Defines the tank shape and allows the Probe LU to calculate volume instead of
level. If None is selected, no volume conversion is performed. Select the tank
shape matching the monitored tank or reservoir (see table on next page).
