5.9 ANALOG OUT
5.9.1 SCALE OUT
In the factory setting, the analog output runs across the entire measuring range (start of measuring range Sdc
- end of measuring range Sde) from 0...10V (voltage mode) or from 4...20mA (current mode).
The start and end of the measuring range can be reset with SCALE OUT, reducing the measuring field and
changing the calibration curve.
The smaller measuring field improves the measurement repetition time, ie, the measuring frequency is
increased.
*The minimum window size (distance from end of the measuring range Sde - start of measuring range Sdc)
must be greater than 5% of the "end of measuring range” value.
OFFSET
The value in mm at which the sensor should have the minimum analog output
value of 0V or 4 mA is specified here.
OFFSET >= Start of measuring range
OFFSET <= End of measuring range – minimum window size*
HEIGHT
The value in mm at which the sensor should have the maximum analog output
value of 10V or 20 mA is specified here. OFFSET represents the basis for this
value.
HEIGHT <= End of measuring range
HEIGHT >= Start of measuring range + minimum window size*
NOTE
The measuring cycles can be shortened by reduction of the window size, i.e. this
increases the measuring frequency, according to data sheet chapter 6.1.
