Calibrating NDIR cuvette
The zero point of the NDIR measuring channels is taken at the end of
the warm-up phase after switching on the analyser (or manually trig-
gered after entering a PIN code).
The user has the possibility to carry out a reference point calibration by
feeding test gas. This calibration is only possible for authorized users af-
ter entering the PIN code.

Connecting analyser to sample gas cylinder
It is recommended to connect the sample gas cylinder to the analyser
via a bypass (see drawing below). The analyser draws an average sample
gas flow of 60 ln/h. The total volume flow from the gas bottle should be
slightly higher than 60 ln/h (approx. 5...10 ln/h higher than 60 ln/h)
