In Lyft and in Lyft PRO, the C-scan can show several different values (click on the icon on top-left

WT%: remaining wall thickness in % referenced to the nominal wall thickness
• WT: remaining wall thickness in absolute units
•
WL%: wall loss in % referenced to the nominal wall thickness
•
CWT% (available only in Lyft PRO): compensated remaining wall thickness in % referenced to
the nominal wall thickness.

Cscan shows the defect minimum wall in reddish colors which are more representative of the true
remaining thickness (with the standard palette). The CWT% Cscan looks as following:
