In the menu "Linearization" and its submenus you can set up and start the calculation to
linearize one channel of an MLT analyzer or analyzer module. With the F3 key you can
change to the other channels. With the F5 key (Info...) you can change to the submenu
"Linearization Info", where you will find the results and some parameters of linearization.

Background:
The optical absorption of a gas as a function of its concentration is not linear in the whole
range. Therefore the result of the analyzer has to be linearized. You can linearize manual
or semi-automatically. In this chapter the manual linearization is described. If you want to
linearize automatically, contact your customer service, please.
