Alarm Setting - YOKOGAWA ZR402G User Manual

(3) Although oxygen concentration measurement "C" has fallen lower than the hysteresis set
value, that measurement exceeds the hysteresis set value before the preset delayed time
has elapsed. So, the alarm is not canceled.
(4) Oxygen concentration measurement "D" has fallen below the hysteresis set value and the
preset delayed time during measurement has elapsed, so the alarm is canceled.
