In the menu "Linearization parameters" you can enable the linearization for each range and you can select the linearization curve.

Note:

Normally, the CLD is working linearly in the whole range. Therefore you do not have to linearize generally ! If you will find deviations from the linearization, you should control the ozone and sample gas supply. Optimize it, if necessary! Usually, the reason for deviations will be a defect in the ozone supply.

Set up parameters:

¨Select any line of variables or the menu line "Set coefficients..." with the ↓ -key or the − -key.

¨Select the variable or change to the submenu "Linearity coefficients" with the ENTER key or the → -key.

¨Select the parameter you want with the − -key or the ↓ -key.

¨Confirm the new value with the ENTER key or cancel and go back to the last value with the F2 key.
