D: nozzle diameter; L: Level
5.6.1 Function "empty calibr." (005)
This function is used to enter the distance from the sensor membrane (reference point of the
measurement) to the minimum level (=zero).
"
Caution!
With dished boiler heads or conical outflows, the zero point should not be deeper than the point
at which the ultrasonic wave impinges on the tank bottom.
5.6.2 Function "blocking distance" (059)
In this function the blocking distance (BD) of the sensor is displayed.
"
Caution!
When entering the full calibration (span), please take into account, that the maximum level may
not project into the blocking distance (BD).
