  • Page 22: Square Root Function

    Low cut-off function: As a part of the square root function of the 4225 it is possible to manually configure a low cut-off point. The feature is often used to suppress noise in the system. The low cut off point defines a point where the input/output relationship either changes to a linear relationship or the output is truncated to zero.
