Offset adjustment 1 The Service tab in the Tank Info window
In our example the offset for bottom pressure sensor for tank C3 shows 300
mmH2O. It has a corresponding Value of 1385 mmH2O. The Value is the
pressure on the sensor currently used for level presentation (level = pressure
divided on density).
Let’s assume that this sensor currently has incorrect offset adjustment, and that
it is necessary to correct it. To make this example simple, we also assume that
the tank contains fresh water with a density of 1.0000.
The correct level in the tank is now 1622 mm and we need to enter a new
offset value. The deviation is 1622-1385= 237, and the correct offset value
should then be 300-237=63.
