3.Warming Up
After turning the power supply ON, allow the product to stand for at least 30 minutes
before use. The circuits are still unstable just after the power supply is turned ON, so
measurement values may fluctuate gradually.
4.Maintenance and Inspection
Do not use thinner, benzene, acetone or kerosene to clean the Sensor and Controller. If
large dust particles adhere to the filter on the front of the Sensor, use a blower brush
(used to clean camera lenses) to blow them off. Do not use breath from your mouth to
blow the dust off. To remove dust particles from the Sensor, wipe gently with a soft cloth
(for cleaning lenses) moistened with a small amount of alcohol. Do not use excessive
force to wipe off dust particles. Scratches to the filter might cause error.
5.Measurement Target
The measurement target is a non-transparent object. The sensor cannot detect the
following types of objects accurately: materials with extremely small reflectances, objects
smaller than the beam diameter, objects with large curvatures, or objects tilted to a large
degree.
6.Effect of Peripheral Lighting
Do not install the Sensor in a place where strong light hits the laser emitter/receiver
section of the Sensor.
Also, if a measurement target has a shiny surface, the light from the lighting will be
reflected and a malfunction may occur. In such a case, prevent reflection by, for example,
covering the light to stop reflection.
