Set [Filt (filter) ].
A trigger is applied when the application condi-
tion of the trigger is met in the period of the set
[Filt] .
This is effective for preventing incorrect opera-
tion caused by noise. The options that can be
set differ depending on the function.

Note: The filter width is 2 samples when the record-

Noise
Filter Width
You can make sure fluctuations within the specified
filter width (number of samples) do not cause the
trigger to be applied even if the trigger condition is
met. This prevents the trigger from being applied
due to noise.
Example: When the number of samples is set to
[10S] , the trigger is not applied if the trigger condi-
tion is not met in 10 consecutive samples.
