4. OPERATION GUIDE 
(1) This combustible gas detector unit is NOT designed 
for anti-explosive measures. Do not use this unit in an 
area where combustible gases can be found. 
(2) The following environmental conditions may cause 
error in the readings: 
  Large temperature variations 
  High wind velocity   
  Organic solvents, adhesive vapors, fuel gas and 
vesicants. Try to avoid environments filled with 
these substances.   
  Places filled with too much combustible gas 
Note: Although this unit will respond to high levels of 
carbon monoxide, it should NOT be used as a detector 
for this gas in normal room or working atmospheres. It 
is used to pinpoint a leak as described in the operating 
instruction.
