Portable analyzer

5. Control procedure
Please carry out the control procedure only outdoors, since the effluent gas can be a health
risk for every person located in a closed room.
First turn the portable analyzer on.
For the inspection of the analyzer, calibrating gases are needed.
Because gas must not be inserted under pressure, the feeding hose of the calibrating gas
bottle has to be interrupted.
It is recommended to use the included hose for this process, see image 1.

To ensure no fresh air or other gases from outside the analyzer are able to enter into the hose, it is
important that more gas flows into it than the analyzer can suck in. This can be identified by gas
escaping the open connector.
Alternatively a small plastic or glass bottle can be used, from which the analyzer can draw a gas
sample through another hose by itself, see Image 2.
The quantity of gas in the bottle has to be a bit larger than the quantity drawn by the analyzer to avoid
air from the outside from entering, see
Image 2: Connection of calibrating gas with a testing
bottle
. This can be identified by gas escaping the
testing bottle.
The plastic or glass bottle with a neck diameter between 20 and 30 mm has to be
absolutely clean and dry on the inside.
There must not be any dust or moisture inside the bottle.
For a reliable measurement, please observe the minimum warm-up time in the lower
right corner of the display until “READY” is displayed in the lower left corner
