Time chart (common to FX-301(P)(-HS)/305(P); however, only the FX-305(P) is
equipped with ON-delay / OFF-delay and ON-delay • ONE SHOT timers.

Available timer periods are:
FX-301(P)(-HS) Timer period T
FX-305(P) Timer period; output 1: T
output 2: T
* OFF-delay : Extends the output signal for a fixed period of time.
This function is useful if the output signal is so short that the connected device
cannot respond.
ON-delay : Neglects short output signals. As only long signals are extracted, this function
is useful for detecting if a line is clogged, or for sensing only objects taking a
long time to travel.
ONE SHOT: Outputs a fixed width signal upon sensing.
This function is useful when the input specifications of the connected device
require a signal of fixed width.
ON-delay • OFF-delay : The ON-delay and the OFF-delay timer functions can operate
simultaneously.
ON-delay • ONE SHOT: The ON-delay and the ONE SHOT timer functions can operate
simultaneously.
Selects the hysteresis from among three different levels (small / standard / large).
* The factory setting is 'H-02 (standard)'.
Permits selection from among three different stability indicator response levels
