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. 

We recommend that you record a partial spectrum from 0.5m above bottom or the liquid level. Also 

refer to Page 39, A4.2 and Page 48, C2.8.

 

 

 

Use this procedure (menu item A4.2 Empty Spectrum) if there are fixed and moving objects in the tank 

that can cause interference 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 interference signals.

 

 

CAUTION!

 

Make sure that the tank is empty or only filled to the minimum level.

 

 

 

INFORMATION!

 

Because the device records the empty spectrum data, it is not necessary to do the procedure again if you 

de-energize the device.

 

 

 

Values and parameters that can be changed are shown between the 

« 

... 

» 

marks in the illustrations that 

follow. Push the keypad buttons in the correct sequence:
