After initial startup and after each change of the filter constant, the filter will set the :ref:`safety_flags_adc_unstable` flag for a defined sample count of: The moving average filter is considered unstable, if the input to output difference is greater than
.. doxygendefine:: ADC_FILTER_STARTUP_CYCLES .. doxygendefine:: ADC_PT1000_FILTER_UNSTABLE_DIFF
In this case, the :ref:`safety_flags_adc_unstable` flag will be set until the filter output converges within the range for at least
.. doxygendefine:: ADC_PT1000_FILTER_STABLE_SAMPLE_COUNT
samples.
If the input value keeps changing or oscillating, the error flag will be permanently set.
The moving average filter's output signal is the Low Frequency (LF) PT1000 resistance signal used for internal PT1000 measurements. The moving average filter's output signal is the Low Frequency (LF) PT1000 resistance signal used for internal PT1000 measurements.
