Installation environment
To use the HPS-LC010 properly and safely, avoid installing it in the following locations. Doing so may lead to
product breakdown.
• Location that is humid, dusty or poorly ventilated
• Location where the temperature becomes high, such as a place exposed to direct sunlight
• Location where there are flammable or corrosive gases
• Location where the product may be directly subjected to vibration or impact
• Location where water, oil or chemicals may splash onto the product
• Location where static electricity is readily generated
Noise control
When the product is installed near a noise source such as a power source or high-voltage lines, noise may cause
a malfunction or failure of the unit. Take corrective actions against noise by using noise filters, laying cables in a
separate conduit, and/or providing insulation when installing the controller and sensor head.
Influence of ambient temperature
Changes in the ambient temperature may cause the measurement to fluctuate. Be sure to keep the temperature
constant at all times. When the ambient temperature changes by 10°C, it takes about 60 minutes until the
temperature inside the unit is uniformly distributed.
Ambient light
Do not use the product near a lighting system that repeatedly turns on and off rapidly. If it is unavoidable to use
the unit in such a place, install a light shielding board or a similar object so that the light will not affect the
measurement.
Warming up
After turning on the power, wait approximately 30 minutes before using. Since the circuit is not stable immediately
after the power is turned on, the measured value may gradually change during this period.
Influence of dust or dirt
The measurement may be incorrect when dirt, dust or fluid such as water or oil interferes with measurement in
the following ways.
• Adhesion on the protective glass: Blow the dirt off with clean air. If dirt persists, wipe the glass surface gently
using a soft cloth moistened with alcohol.
• Adhesion on the surface of the measurement target: Blow the dirt off with clean air or wipe it off.
• Intrusion of floating dust or splash of fluid into the light-axis range: Take corrective action such as installing a
protective cover or air purge.
Other considerations
Influence of vibration
When the measurement target is vibrating, the measured value may fluctuate. In this case, increase the number
of averaging measurements to ensure more accurate measurement.

Hypersen Technologies Co., Ltd. HPS-LC010
September 2018 Rev.1.1 4/70
Measurement target
The measured value may be incorrect if the shape or surface condition of the target varies with individual targets.
In this case, measure a known target and use the calibration function to correct the error.
Handling
Do not wipe the unit with a wet cloth, benzene, or thinner. This may cause discoloration or deformation of the
housing. If the unit becomes dirty, wipe it off with a cloth moistened with a mild detergent and then wipe with a
soft dry cloth.
Effect of atmospheric motions
Slow atmospheric motions may affect the measurement and result in fluctuation of the measured value. In such
a case, enclose the sensor head in an appropriate enclosure.
