modules. 
4. If both the measured values of the 
external and internal AG modules in 
step 3 are lower than 0.8% or higher 
than 1.2%, replace the electronic 
vaporizer. 
5. If only the measured value of the 
internal AG module in step 3 is 
lower than 0.8% or higher than 
1.2%, replace the internal AG 
module (refer to 11.1.7).
