4.4 Empty spectrum recording
The empty spectrum recording procedure is important for the performance of the device. We
recommend that the tank is empty or only filled to the minimum level before you do the
procedure.
Use this procedure (menu item 2.1.2 EMP.SPEC.REC.) if there are fixed and moving objects in the
tank that can cause parasitic signals. The device does a scan for objects that do not change their
vertical positions in the tank (heating tubes, agitators, fuel assemblies etc.) and records the
data. The device can then use this data to put the measurement signal through a filter (empty
spectrum).
When the empty spectrum filter is on (when menu item 2.3.12 EMP.SPEC.EN. is set to "on"), it
will ignore the parasitic signals. Because the device records the data from the procedure, it is
also not necessary to do the procedure again if you de-energize the device.
CAUTION!
Make sure that the tank is empty or only filled to the minimum level.
Before you do the empty spectrum recording procedure, install the device on the tank. For more
data about how to install the device, refer to the handbook.
