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.
