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.
