Up to 30 events may be saved, the oldest data will be automatically substituted with the newest one. The saved 
data can be downloaded to PC through SENSOTRAN IR-LINK. 

Data log records the operation status every second for more than 2 months.

Calibration 

<Caution>  The  initial  calibration  is  executed  at  SENSOTRAN  S.L.  before  device  shipment.  The  calibration 

values are saved in the device which means inaccurate calibration may impair the accuracy of the device 

performance. User should perform calibration every six months.   

 

<Caution> Because it is calibrated on the assumption that oxygen concentration is 20.9%vol, the combustible 

gas is 0%LEL, and the toxic is 0ppm in the normal fresh atmosphere, fresh air calibration must be conducted 

in  the  absolutely  clear  air  without  any  impact  of  other  gases.

 

Fresh  air  calibration  in  the  airtight  spaces 

therefore is not recommended. Make sure to avoid calibration under the work environment where gases may 

be present. 

 

 

5.1. 

Fresh Air Calibration 

 

 

 

   

Press KEY button (        ) for 3 seconds under the gas calibration value mode and the icon (      ) for fresh air 
calibration will appear on the display with the message “CAL ZERO.” Press for another 3 seconds to do fresh air 
calibration and it will take 10 seconds to calibrate. Press the button during the calibration process to abort the 
calibration. If you press the button upon the completion, it will return to the fresh air calibration mode, and if 
you don’t press the button, it automatically enters the measure mode. 

 

If the calibration fails, message FA(Fail), appears on the display. Press the button to enter 
the initial fresh air calibration mode and it changes into the measure mode if you do not press 
the  button  for  3  seconds.  If  FA  continues,  please  consult  SENSOTRAN  or  your  local 
distributor as it may require the replacement of the sensor or maintenance tasks.
