Filters
Filters can be applied to measurement values before they are output from the Gocator sensors.
All measurements provide filter settings under the Output tab.
Filter Description
Scale and Offset The Scale and Offset settings are applied to the measurement value according to the
following formula:
Scale * Value + Offset
Scale and Offset can be used to transform the output without the need to write a script. For
example, to convert the measurement value from millimeters to thousands of an inch, set
Scale to 39.37. To convert from radius to diameter, set Scale to 2.
Hold Last Valid Holds the last valid value when the measurement is invalid. Measurement is invalid if there
is no valid value.
Smoothing Applies moving window averaging to reduce random noise in a measurement output. The
averaging window is configured in number of frames.
If Hold Last Valid is enabled, smoothing uses the output of the Hold Last Valid filter.
To configure the filters:
1. Go to the Measure page by clicking on the Measure icon.
The scan mode must be set to the type of measurement you need to configure.
Otherwise, the wrong tools, or no tools, will be listed on the Measure page.
2. In the Tools panel, click on a tool in the tool list.
