6.2.16 Nominal distance of the distance sensor (nominal load)
In this line you can set the nominal distance for the distance transducer used. The
nominal distance is specified in mm. The nominal distance is achieved at the maxi-
mum measuring signal (10
V) of the distance transducer. In the above example, the
sensor has an output voltage of 10 V for a distance of 50 mm.

Tap on the input field behind 'Nominal distance'. The input window containing the
numerical keypad appears.

Enter the nominal distance using the numerical keypad (enter a point before dec-
imal places; if no decimal places are entered, then the display shows two decimal
places '.00').

Confirm the entry with the 'ENTER' button.

By tapping on the measurement unit, a window with an alphanumerical keypad
appears. You may enter 4 characters for the measurement unit.

When using a resistance potentiometer, you must enter the potentiometer re-
s
istance in kΩ (as per data sheet) in order to optimize the linearity of the measuring
chain.
6.2.17 Distance sensor offset
In this line the offset value of the measurement signal is entered in mm.
The 'Offset' parameter adjusts a possible zero point displacement of the analog meas-
urement signal of the sensor.

Tap on the input field behind 'Offset'. The input window containing the numerical
keypad appears.

Enter the offset value using the numerical keypad (enter a point before decimal
places; if no decimal places are entered, then the display shows two decimal
places '.00').

Confirm the entry with the 'ENTER' button.
6.2.18 Offset adjustment of distance sensor
By tapping on the 'offset adjustment' button, the actual analog measur-
ing signal of the transmitter is taken as offset.
An offset adjustment is always necessary after changing or adding a distance trans-
ducer. Make sure the distance transducer is not loaded during the alignment.
Note
Generally, an offset adjustment should be carried out at least once a
day or after about 1000 measurements
