3.6 Measured value technology
After application of the supply voltage and initialization, the device is ready for mea‐
surement.
The quality of the measured values in relation to noise and reliability can be optimized
in line with the given application. The following parameters are available here.

Measurement cycle time
Increasing the measurement cycle time causes a rise in sensor detectability. A mea‐
sured value can thus be created from very low signal strengths.
In product variant DT1000, the scalability of the range results from this: the longer the
set measurement cycle time, the larger the range of the sensor, see figure 30,
page 98.
For more information on the measurement cycle time, see "Defining the measurement
cycle time", page 54.
