3.4 Measuring characteristics

Multiple measuring characteristics are available in the FLS-C measuring devices to meet different requirements for various applications. With
these measuring characteristics measuring rate and accuracy can be optimized for special requirements.
The FLS-C measuring device at factory settings has an accuracy of ±1 mm (FLS-C(H) 10) respectively ±3 mm (FLS-C(H) 30) at 2σ. Measuring
rate depends on environmental conditions such as target surface, distance, background light (e.g. sun light), etc. Good environmental
conditions increase measuring rate (e.g. white target surface or orange reflective target plate and dark environment).

Configuration command: sNuc+0+3
The device does not check the signal condition to ensure the
specified accuracy is reached, a measurement value is transferred
to the output at a defined measuring rate.

This mode serves for applications where the accuracy is not
important but the reaction time is critical
Configuration command: sNuc+1+1
The device measures to a continuously moving target and the
distance changes without any jumps.
This measurement characteristic supervises the max speed,
checks for distance jumps and includes a special filter to
