We recommend that the tank is empty or only filled to the minimum level before you do the procedure.Use this procedure (menu item A4.2. Empty Spectrum) 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 C2.8 Empty Spectrum Enable is set to "Enable"), 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.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 Installation on page 22.Values and parameters that can be changed are shown between the «... » marks in the illustrations that follow.
