Change of gas alarm sensitivity for differential measuring 

mode (only for fumigation gases) 

1 

In the detection mode, press the AIR button. 

The alarm sensitivity changes by two every time the AIR button is pressed. 

 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

NOTE 

•

  For switching to the differential measuring mode (for fumigation gases), see "Change of the 

measuring mode" in the display mode on page 31. 
 

 

 
 

 

 

          CAUTION 

•

Keeping contact with a gas with the same concentration will decrease the bar meter by the 
automatic air calibration function. 

•

For excessive temperature/humidity changes, the bar meter may increase. 

•

When the mode is switched from the differential mode to the concentration measuring mode, 
check the atmosphere for cleanliness and perform air calibration again in the measured 
atmosphere. 

•

The gas concentration is displayed in six levels (without a unit). 

•

Air calibration is performed automatically and it cannot be performed manually.
