8.7.3  Alarm Thresholds / Hysteresis 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

For each measuring point four alarm thresholds are available for free definition. If the gas concentration is 
higher than the set alarm threshold, the associated alarm is activated. If the gas concentration falls below the 
alarm threshold minus the hysteresis the 

alarm is reset again. In the mode “Alarm at falling” the corr

esponding 

alarm is set in case of falling below the set alarm threshold and reset again when exceeding the threshold plus 
hysteresis.  

The presentation of the alarm thresholds depends on the set measuring range: See chapter Gas Type and 
Measuring Range.  

The alarm thresholds are freely selectable in the range from 0 to 100 % of the measuring range. 

The alarm threshold is 

only stored, if the value is ≥ 

than the lower alarm threshold 

Unused alarm thresholds have to be defined with 0, in order to avoid undesired alarms.  

Higher-level alarms automatically activate the lower-level alarms. 

Lowest hysteresis: 3 % of the lowest alarm threshold 

Highest hysteresis: 50 % of the lowest alarm threshold
