Hysteresis
Alarm hysteresis
-99999~99999
Note: hysteresis is designed to prevent repeated alarm due to vibration
of measurement value around alarm point. Figure 4-1 is a legend of high and
low alarm and hysteresis. Upon high alarm, when the actual engineering
value is greater than or equal to the alarm value, the recorder enters the alarm
state. When the input decreases, the actual engineering value is less than the
alarm value, and the recorder will not immediately exit the alarm state, but
until the actual engineering value is less than the difference between the
alarm value and the hysteresis value, the recorder will exit the alarm state. So
is low alarm.
