ANGLE CHARACTERISTICS (TYPICAL EXAMPLE)
The angle characteristics were obtained by detecting an object with different angles of inclination at the measurement point and plotting
the linear output error resulting from each operation.

LINEARITY CHARACTERISTICS vs. OBJECTS (TYPICAL EXAMPLE)
Linearity characteristic curves are obtained by detecting an object at different positions within the measurement range and plotting the
linear output error resulting from each operation.
