Gocator Line Profile Sensors: User Manual

All measurements provide filter settings under the Output tab. The following settings are available.
Filter Description
Scale and Offset The Scale and Offset settings are applied to a 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.
For more information on scripts, see Scripts on page 313.
Hold Last Valid Holds the last valid value when the measurement is invalid.
Smoothing Averages the valid measurements in the number of preceding frames specified in Samples.
Use this to reduce the impact of random noise on a measurement's output.
If Hold Last Valid is enabled, the smoothing filter uses the last valid measurement value
until a valid value is encountered.
Preserve Invalid When enabled, smoothing is only applied to valid measurements and not to invalid results:
invalid results are not modified and are sent to output as is.
When disabled, smoothing is applied to both valid and invalid results. (This setting is only
visible when Smoothing is enabled.)
If Hold Last Valid is enabled, results will always be valid, in which case this setting does
nothing.
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.
3. In the measurement list, select a measurement.
