OPERATION
6
Menu items related to level measurement are:
• Output Function (C.3.1 or C.4.1)
• Tank Height (C.1.2)
• Blocking Distance (C.1.9)
Use the silo bottom as the reference point for the 4 and 20 mA current output settings. The 4 and
20 mA current output settings are the minimum and maximum points of the measurement scale.
You can change the reference point from which level is measured. Use this menu item:
• Tank Bottom Offset (C.1.11)
INFORMATION!
If you move the tank bottom offset below the silo bottom, add this value when you give a level for
the 4 and 20 mA current output settings. If you move the tank bottom offset above the silo
bottom, subtract this value when you give a level for the 4 and 20 mA current output settings.
CAUTION!
If the level for the 20 mA is set in the blocking distance, the device will not be able to use the full
current output range.
