Bottom Offset" (C.1.11). If you move the reference point below the tank bottom, add this value
when give a level for the 4 and 20 mA current output settings. If you move the reference point
above the tank bottom, subtract this value when you give a level value for the 4 and 20 mA
current output settings.
