Verify level
The Verify Level tool matches the product level reported by the device to a reference
measurement (measured by using for example handgauging).
If any difference, the Calibration Offset parameter will be adjusted. A minor adjustment
using Calibration Offset is normal. There may, for example be a deviation between the
actual tank height and the configured value.
