value of 1 provides an output of one sec-
ond on and one second off (50% output). A
pulse value of 2 provides an output of one
second on and two seconds off (33% out-
put). Output at center of band equals one
second on, 2
(pulse value-1) seconds off.

a fast response process the value should
be lowered (less Rate). For a slower pro-
cess the value should be increased (more
Rate).
