No
: Parameters cannot be changed using SigmaWin+ while this function is being executed.

After the detection completes normally, press the MODE/
SET
Key. The optimum notch filter for the detected reso-
nance frequency will automaticall
y be set. When the notch
filter is set correctly, the "donE" flashes and then the display
shown on the left appears.
When the 1st notch filter frequency is already set
(Pn408.0=1), the 2nd notch filter frequency will be auto-
matically set (Pn40C).
Press the MODE/SET Key to return to step 5.
Notes:
• If both the 1st and 2nd notch filter freq
uencies are already
set (Pn408 = n.11), no more notch filter frequencies
can
be set.
• Set Pn408.0 to 0 (disables notch filter) not to use the
notch filter frequency detected by
executing the EasyFFT
function.
