Scaling the current output
1) Drain the tank completely to the 0% marking (= 4 mA)
2) Press the lower keys (↵ and ↓ ) down, until the
asterisks on the display "TANKHEIGHT|********" are
replaced by the actual measured distance value
3) Then release and press ↵. In the lower line: "SURE
NO?" is displayed.
4) If this value is not plausible or the tank is not empty,
abort by ↵. Or accept the value by pressing . ("SURE
YES?") and then ↵.
5) Now the tank height is set.
6) In the next step you can also enter this value as 4 mA
scaling (0%). Press ↵. In the lower line now: "SURE NO?"
is displayed again.
7) If this value shall not be stored, abort by ↵. Or accept
this 4mA scaling by pressing . ("SURE YES?") and then ↵.
8) Fill the tank to the 100% mark. Use the same procedure
for the 100% point = 20 mA only now by pressing the top
keys → and ↓.
9) First the measured distance can be taken as block
distance. After this you can enter or adjust the 20 mA point
(100%) according to the actual level.

This example was written for the case: current output = level (default). For distance measurement the
points 0% (short distance = high level) and 100% (large distance = low level) are exchanged.
If no reliable measurement is possible "NO ACCESS" is displayed. Abort by pressing ↵.
