operation when you press [SAVE/SEND]:
○ ACTIVE: Saves only the active measurement (the highlighted thickness)

you created in step 1 for each of the layers. Selecting NONE shows no
thickness at the location.

which you want to sum the thickness measurements.

multi-measurement function active in the normal mode.
7.4.3 Using the Multi-Measurement with the Soft Contact Mode
Before you can use the multi-measurement function, you must create and save custom
setups for the sagittal height and the lens thickness measurement. The 38DL PLUS
calculates the radius of curvature using the sagittal height value and the diameter of
the pedestal that you enter.
