Analog Output

Only one measured value can be transmitted. The resolution of the analog output is 16 bit.
Output signal 01DIST1 / ... 01DIST6 / ... The data selection depends on the current setting and includes the results
Output range 4 ... 20 mA / 0 ... 5 V /
0 ... 10 V
Scaling Standard scaling
Two-point scaling
The first value corresponds to the start of the measuring range and the second value to the end of the measuring range.
If the analog range needs to be moved, we recommend using the zeroing or mastering function.
Two-point scaling enables the user to specify separate start and end values (in mm) for the sensor's measuring range.
The available output range of the analog output is then spread between the minimum and maximum measured values.
This allows for decreasing analog characteristics,
