For regular reflection heads (such as ZS-HLDS2T and ZS-LD20T)
By fixing the Sensor Head to a position such that it is kept in
parallel with the front side of the workpiece, you can perform
high-precision measurement. When you install the Sensor Head,
we recommend that you match the front side of the workpiece
with the reference surface of the Sensor Head, and then bring
up the Sensor Head horizontally and install it.

For diffuse reflection heads
Adjust the position of the Sensor Head while checking the
display of the emitted light amount and received light amount.
Adjust the position of the Sensor Head such that the emitted
light amount becomes the minimum compared to 1,000 for the
received light amount.
