4.3.5 Measuring length – linear application
The maximum measuring length of the system is 48 m.
For correct function while maintaining the specified system
accuracies, the magnetic tape length must be greater than
the desired measuring length. There needs to be a reserve
at the beginning and end of the measuring range.
