5.1 TROUBLESHOOTING GUIDE
Cause 2 : TL-100 senses refractive power change along the
progressive extent. If the power change is close to 0 diopter, the
TL-100 treats it as a near point.
Example:
When a lens with a SPH reading of -1.00 diopters and an add
reading of 2.00 diopters is measured, there is a point where the
total refractive power (S + ADD) equals zero (0) diopters. As a
result, the ADD value would be displayed as 1.00 diopter.
Action : Use manual mode for these lenses.
If the cursor changes
twice from “+” to “ ” (or “ ”),
use the highest reading as the ADD.
If the cursor changes only once to “
,” take the highest
reading as the ADD.
