Manual pulse generator 1 (P1) : D752
Manual pulse generator 2 (P2) : D753
Manual pulse generator 3 (P3) : D754
(b) When the smoothing magnification is set, the smoothing time constant is as
indicated by the following expression.
Smoothing time constant (t) = (smoothing magnification + 1) × 56.8 [ms]
