Function description
This menu item shows the ullage volume
readings measured at this time. This
measurement data is shown with the
units set in menu C7.5 Units. This menu
item is only available if you set up a
conversion (volume) table in menu item
C3.1 Edit Table.
This menu item shows the ullage mass
readings measured at this time. This
measurement data is shown with the units
set in menu C7.5 Units. This menu item is
only available if you set up a conversion
(mass) table in menu item C3.1 Edit Table.
Temperature of the sensor electronics
block.
Temperature of the converter electronics
block. Operation of display can stop if the
temperature is below - 20°C / -4°F or
above +70°C / +158°F.
This menu item shows the raw spectra data
of the radar signal which makes a reflection
on the surface of the tank contents and is
received by the device. This data is shown
as a graph of the percentage of the full-
scale signal against distance.
This menu item shows the corrected
spectra data of the radar signal which
makes a reflection on the surface of the
tank contents and is received by the
device. This is the result of the spectra
data from an empty tank subtracted from
the power spectra data. This data is
shown as a graph of the percentage of the
full-scale signal against distance.
This menu item shows the spectra of the
radar signal which makes a reflection on
objects inside an empty tank (interference
signals). This data is shown as a graph of
the percentage of the full-scale signal
against distance. It is also possible to do
an empty spectrum scan in a partially full
tank, if it is not possible to remove all the
tank contents.
