Notice for User

 

 

 

 

 

 

Please  use  the  instrument  in  the  range  of  the  applicable  temperature, 
humidity  and  pressure  that  are  appropriate  for  the  specification  of  the 
product. Using the instrument beyond this range may cause malfunction 
or glitch of the instrument.

 

Gas  concentration  measurement  value  by  the  sensor  or  the  instrument 
can vary according to the environment at site (temperature, pressure and 
humidity). Therefore the calibration of the instrument should be performed 

at  the  same  or  similar  environment  as  that  of  the  instrument  use 
(temperature, pressure and humidity).

 

If temperature changes sharply during use of the instrument (for instance, 
using  the  instrument  at  places  of  far  different  temperatures  between 
indoor and outdoor), the value of the measured gas concentration can be 
changed  suddenly.  Please  use  it  after  the  gas  concentration  value  is 
stabilized.

 

Severe vibration or shock to the instrument may cause the sudden change 

of value of the measured gas concentration. Please use it after the value 
of gas concentration is stabilized. Excessive shock to the unit can lead to 
trouble of the sensor or the instrument.
