Place and screw the cover over the sensors (Figure 16: positioning the sensors
cover (BM 25A/AW non-equipped with an electric pump)ref. 1); this cover has no
hump as previously mentioned (ref. 4).
■
Connect the sample line (ref. 2) to the gas inlet (ref. 3).

recorded too soon, they may be over-estimated (combustible gases), or under-
estimated (oxygen).
Once the sampling is complete, remember to remove the sensors cover to
return to diffusion mode.
