Setting options (∗. default setting)
(When High-speed Function)
Set by number of samples
Off∗, 10S, 20S, 50S, 100S, 200S, 500S, 1000S
(S = Number of samples)
(When Real-time Function)
Off, On (When this is On, the filter width is fixed to 10
ms.
Note: The filter width is 2 samples when the recording
interval is 10 ms or longer.
