    User-defined scaling can be used for the following applications:  An incremental encoder counts from 0 to 360°. The user-defined scaling function converts the values in a way that the module JX3-CNT outputs numbers from 0 to 360.  A counter is used to measure a physical length. The module JX3-CNT converts the values so that the output is proportional to micrometers.
