When you enable extended filtering with the Extended filtering on/off selection, you can define a custom filtering factor for the measurements.
The filtering factor determines how much weight the most recent measured value has in the measurement reading. You can use the filtering factor to average the measurement reading over time.
Maximum value in the device-specific range = No filtering. Reading shows 100% of the most recent measured value.
Less than maximum value in the device-specific range = Filtering is applied. For example, defining a value that is 90% of the maximum value means that the filtered measurement reading = 90% of the most recent measured value + 10% of the previous reading.
