5.3.3 Empty and full calibration
Function Remarks
"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.

BD Blocking distance F Full calibration (= span)
SD Safety distance D Nozzle diameter
E Empty calibration (= zero point) L Level
"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).
!
Note!
After basic calibration, enter a safety distance (SD) in the "safety distance" (015)
function. If the level is within this safety distance, the device signals a warning or an alarm,
depending on your selection in the
"in safety distance" (016) function.
"full calibr." (006) This function is used to enter the distance from the minimum level to the maximum level
(=span).
