filter_k

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 coefficient

filter_k comp_in_p .5[hz]
Specifies cutoff frequency

filter_k comp_in_p 2[sec]
Specifies time constraint

filter_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.
