How to interpret the table
Example: Tuning (without a workpiece) of
model HP7-A1_against a matte SUS
background at 1 m where white paper target is
detected at distances of up to approx. 0.5 m.

Target
When used with highly reflective backgrounds, tilting
the switch may improve background suppression.
