VARIABLE HYSTERESIS FUNCTION (E3X-H11)
Detecting operation is not stable
because zone B is within the
hysteresis differential range.
Decide the position of
the fiber head and that
of the sensing object in
zone A.
Locate the head in
zone A and turn the
sensitivity adjuster
counterclockwise slowly
until the stable operation
indicator and light reception
indicator are OFF (i.e.,
position E as shown in
the illustration).
Set both the sensitivity
adjuster and hysteresis
adjuster to maximum.
