Outlier, Delta Values
Figure 67. Outlier, Delta Values properties
| Property | Value | Description |
|---|---|---|
| High Limit | null check box (defaults to checked) or numeric value | Optionally, defines a number above which a data value (an outlier) should be excluded from an analytic calculation.
Setting a limit is similar to using a RangeFilter block in an algorithm where values greater than the high limit are excluded from being processed and using an InvalidValueFilter to filter NaN numbers without the benefit of also filtering infinite values. A use case might be that you have a sensor with a range of 0-150 deg F, any readings above 150 would be anomalies or suspect values, which need to filtered out. |
| Low Limit | null check box (defaults to checked) or numeric value | Optionally, defines a number below which a data value (an outlier) should be excluded from an analytic calculation.
Setting a limit is similar to using a RangeFilter block in an algorithm where values lower than the low limit are excluded from being processed and using an InvalidValueFilter to filter NaN numbers without the benefit of also filtering infinite values. A use case might be that you have a sensor with a range of 0-150 deg F, any readings below zero would be anomalies or suspect values, which need to filtered out. |
