filter_k
Purpose:
-
Set or display the filter coefficient for a specified AI or FI channel based on command-line input.
Enter:
-
filter_k <channel_name> [value[units]]
Where:
-
channel_name
Specify the name of an AI or FI channel.
value[units]
Optional. Specify a value followed by units in brackets, where the value can be a filter coefficient (0.0 to less than 1.0), a frequency cutoff in [hz], or a time constant in [sec].
Example:
-
filter_k comp_in_p 0.10
Specifies recursive filter coefficientfilter_k comp_in_p .5[hz]
Specifies cutoff frequencyfilter_k comp_in_p 2[sec]
Specifies time constraintfilter_k comp_in_p
Displays current settings
Notes:
-
The filter coefficient is used to smooth transient responses in analog input signals. Values must be between 0.0 and less than 1.0, as the program rejects out-of-range values.
