Scale and Offset Processor¶

The “Scale and Offset Processor” is installed with the Dataristix Application. The processor scales and/or offsets values as configured, retaining the data types and qualities of the input values. If the input value is a one-dimensional array, the scale and offset are applied to each element individually.

Add to Task¶

Add the “Scale and Offset Processor” to a task by dragging it from the “Build” panel onto the task’s “Task Builder” panel.
