Alarm 1 Set Point
The set point band is defined as the actual value of the set point plus or minus the
hysteresis value. The hysteresis value is fixed at 0.2% H
2
in Air. Alarm action occurs if the
input value is above or below the set point band. If the input moves within the set point
band, the last alarm action is maintained.
The
Alarm 1 Set Point
can be set to any value within the input range being displayed. The
decimal point position is set automatically. The alarm LEDs are illuminated in the alarm
condition.
