Note
The pressure sensor (see Pressure sensor on page 33) is installed as an option.
For a precise pressure correction as well as for measurements in suppressed measuring ranges, the sensor and sample gas outlet
have to be connected to each other via a T-piece and with the use of short conductors.
The lines must be as short as possible or – in the case of a greater length – have a sufficiently large inside diameter (min. 10 mm) so
that the flow effect is minimized.
