8.8.4  Power On Time 

 
 
 

Gas sensors need a warm-up time, until the chemical process of the sensor reaches stable conditions. During 
this running-in period the sensor signal can lead to an unwanted triggering of a pseudo alarm. Therefore, the 
Power On time is started at each basic unit and each sensor head after power-on or voltage recovery. While 
this time is running out, the 

device is in special mode and doesn’t activate alarms. The Power On time appears 

in  the  starting  menu.  During  this  phase  the  sensor  head  transmits  "Warm-up  time"  instead  of  the  measured 
value. 

The Power On Time of the individual components may be different. Only when the longest time has expired, 
the system starts the measuring operation.

8.8.5  Deadband 

 

 

The unwanted noise of the measured value around the zero point, caused by the basic drift of the sensor, can 
be suppressed by activating a deadband with a range of 0% to 15% of the measuring range depending on 
device. 

If the measured value is within the set % value, the display shows 0. Natural zero-point fluctuations of sensors 
downwards or upwards can thus be suppressed in the display. Default setting 0 means deadband deactivated. 

The suppression also affects the analog output, because the measured value must not assume a different 
display depending on the output. 

When opening the calibration mode, the deadband function switches off automatically.
