Sets an appropriate sensitivity according to the change in target surface

condition.

Set the sensitivity to AUTO for normal use.

AUTO:

Used to measure various objects: from objects with low reflectance such

as black rubber, to ones with high reflectance such as metals.

Note: If the reflectance of the target changes greatly during a short

cycle, the analog output may become unstable with the AUTO setting.

In this case, set the sensitivity to HIGH or LOW.

HIGH:

Fix the sensitivity to high. Used to measure a part with low reflectance

(black) in the above condition.

LOW:

Fix the sensitivity to low. Used to measure a part with high reflectance in

the above condition.

USING EACH FUNCTION SENSITIVITY SETTING

Example: Measurement of pin warpage

In measuring the warp of moving connector pins, the reflectance of the

pin and gap changes greatly, causing a change in the analog output in a

short time period. In such a case, set the sensitivity setting switch to

LOW and measure only pins that have a high reflectance.
