Calibration curve 

792 BASIC IC / Method / Calibration / Graphs 

Selecting this menu item or clicking on 

<Graphs>

 in the component table 

opens the 

Component

 window. 

 

In this window the results of the calibration are shown for each compo-

nent together with the calibration curve. The parameters for calculating 

the calibration curve can also be entered here.
