• We recommend that you take substantial safety measures to avoid any damage in the event a problem occurs.
• Do not open or modify the LT-9001 Series or use it in any way other than described in the specifications.
• When the LT-9001 Series is used in combination with other devices, functions and performance may be degraded, depending on operating conditions and the surrounding environment.
• Do not use the LT-Series for the purpose of protecting the human body and lives.
• Do not change the temperature around the LT-Series including peripheral devices. Condensation may lead to malfunction.
Follow the safety precautions below to ensure operator safety.
• Apply the voltage correctly. Failure to do so may cause fire, electric shock or malfunction.
• Be sure to connect the earth ground terminal on the adaptor inlet of the controller. Failure to do so may cause electric shock and malfunction.
• Do not open or modify the unit. It may cause a fire or electric shock.
Handling the abnormalities
Turn off the power immediately in the following cases. Using the unit in an abnormal condition could cause fire, electric shock, or accident. Contact your nearest KEYENCE office for repair.
• If liquid including water, chemicals or debris enters the unit
• If the unit drops or the case is damaged.
• If abnormal smoke or smell occurs.
Follow the safety precautions below to ensure operator safety.
• Be sure to turn the power off when you plug/unplug the cable which connects the unit and the devices connected to the unit. Otherwise damage could result.
• Do not turn the power off while setting up the unit. Part or all of setting data may be lost.
• Do not block the vent holes on the unit and peripheral devices. Otherwise, excessive heat can build up and cause failure.
Installation environment
To use the LT-9001 Series correctly and safely, avoid installing it in the following locations:
• Locations that are humid, dusty or poorly ventilated.
• Locations with a high temperature such as a place exposed to direct sunlight
• Locations where there are flammable or corrosive gases.
• Locations where the unit may be directly subjected to vibration or impact.
• Location where water, oil or chemicals may splash onto the unit.
• Locations where the static electricity is easily generated.

Safety Precautions
Corrective action for noise
Do not install the LT-9001 Series near power sources or high tension cables, otherwise noise may cause the LT-9001 Series to malfunction. Take corrective action for noise by using noise filters, by separating these cables, by installing insulations to the controller and to the measuring unit.
Laser safety precautions
The LT-9001 is classified as a class1 laser product by IEC60825-1. (FDA class IIa)
• Caution - use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
• Do not stare into the laser beam directly for a long time.
• Do not disassemble the LT-9001 Series.
The Influence of ambient temperature
A change in ambient temperature may cause measurement fluctuations. Be sure to keep the temperature stabilized. When the ambient temperature changes 10 °C, it takes 60 minutes to equalize the distribution of the inside temperature.
Warming up
Before using the LT-9001 Series, wait approximately 60 minutes after the power is turned on. Otherwise, the measured value may gradually fluctuate because the circuit is not stable immediately after the power is turned on.
The Influence of dust or dirt
The measurement may fluctuate due to dirt, dust or fluid such as water or oil in the following cases:
• On the LT-9001 optics: Blow the dirt off with clean air. If dirt persists, wipe the glass surface gently using soft cloth soaked with alcohol.
•On the target surface: Blow the dirt off with clean air or wipe it off.
• Airborne: Build a protective enclosure with an air purge system around the measurement area.

Note

Influence of vibration
When the measurement target is vibrating, the measured value may fluctuate. In this case, increase the number or times the measurement value is averaged to achieve more accurate measurements.
2
E LT-9001-IM
Measurement target
The measured value may fluctuate when the shapes or surfaces of targets vary. In this case, use a known target and perform appropriate correction with the calibration function.
Scan straightness
The scan orbit of the LT-9001 Series makes a slight arc. Therefore, the measured value may fluctuate when the target is slanted.
Handling
Do not wipe with a wet cloth, benzene, or thinner. Doing so could change the color or shape of the lens. If the lens has a lot of dirt on it, wipe it off with a cloth moistened with a mild detergent, then wipe with a soft dry cloth.
Effect of atmospheric motions
Slow atmospheric motions may affect the measurement resulting in the measured value fluctuation. In such a case, take the following countermeasures.
• Enclose the measurement portion with the appropriate enclosure.
• Agitate the air between the measurement point and the workpiece strongly with the fan.
Best Management Practice for Perchlorate Materials - California only
When you sell, manufacture and/or waste the products containing perchlorate material in California, the following statement must appear on the exterior of all outer shipping packages and on consumer packages, based on California Code of Regulations.
E LT-9001-IM
"Perchlorate Material – special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate."
Note: Alternative option is to indicate this statement on your MSDS or manual accompanying with each product.
This product includes a CR coin type cell containing perchlorate material. If you ship this product (or your product including this product) to California, you must ensure to comply with this regulation.

The displacement mode enables you to measure a targed in four ways such as displacement, transparent object thickness, slant, and Δslant of the target by measuring the changes in the distance from the reference point.

Profile Mode

The profile mode enables you to measure the target shape by using the measured value of each scanned point. You can also measure the average value, maximum value, minimum value, differential between the maximum and the minimum value, and area by specifying two different areas on the target.
