source to find the angle reflected upon a device
under test (DUT)
*For the internal light source, the angle 2θ is
measured and the value of θ is calculated as a
result.
A method to measure the angle of a beam from
internal light source reflected up on a device
under test (DUT). The angle 2θ is measured to
calculate the θ as result.
External Incident Light Angle
Measurement
Measurement method to find angle by directly using
light flux of laser or LED.
For an external incident light, the value of θis
displayed as it is.

1. For your Safety –Precautions of Use
1.1 Warning labels addressed in this Manual
May result in serious injury, damage to equipment, or other
serious damage.
May result in minor physical injury or equipment damage.
Instructions for safe handling are provided for the product.
1.2 Handling this Product
➢The Products uses a laser diode for its internal light source. It is recommended that the
products are in an environment where appropriate safety measures are taken for the
laser class before any use.
➢The function and performance of the Products will not be guaranteed if the Products
were used in a manner other than that specified in this Manual, or if the Products has
been modified.
➢When the Products are used in combination with other equipment, the functions and
performance may not be fulfilled depending on your design, operating conditions, and
environment.
➢Do not subject each device, including peripherals, to sudden temperature changes.
Doing so may cause condensation and equipment failure.
➢Do not wipe the product with a wet rag, benzene, thinner, or the alike. Doing so may
cause discoloration or deformation of the Product. If the Product is heavily soiled, wring
out a cloth with diluted PH-neutral detergent and wipe off the stain, then dry the
Product with a soft cloth.
➢If the Product should malfunction, please contact our local sales office.

12
1.3 Precautions
1.3.1 Ambient Temperature and Illuminance
・Changes in ambient temperature can cause measurement errors. Please be advised to
keep the ambient temperature, always, at a constant level.
・Avoid using the Product near lighting equipment that repeatedly turns on and off at
high frequencies. If this is not possible, use a light shield or similar device to avoid being
affected.
1.3.2 Power Supply
・Use the correct power supply voltage. Failure to do so may result in fire, electric shock,
or malfunction.
・Be sure to turn off the power to the Product and devices connected to the Product
when connecting or disconnecting various connecting wires. Failure to do so may
result in damage to the Product.
・Do not turn off the power while setting items. Sudden power cut-off while setting data,
part or all configuration data may be lost.
1.3.3 Disassembly/Modification
Do not disassemble or modify the unit. Doing so may cause fire or electric shock. The
warranty is void if the Product is disassembled or modified by anyone other than our
employees or our certified third party.
1.3.4 Effects of dust and dirt
The following cases may cause measurement errors due to the influence of dust, dirt,
water, oil, etc.

13
・Dust and dirt on the cover glass: Use dry-clean air to blow off any dirt on the cover
glass. If the cover glass is heavily soiled, wipe it off with a soft cloth soaked in thin
alcohol.
・Adhesion on the surface of the object to be measured: Blow it off with clean air or
wipe off the dirt.
・Intrusion into the optical axis area by floating or by splashing: Take measures such as
installing a protective cover or air purging.
1.3.5 Influence of Vibration
・Vibration to a DUT may cause the measured value to vary. In such a case, a more
accurate measurement can be obtained by increasing the number of times the
measured values are averaged.
1.3.6 Disturbance by the air fluctuation
The influence of slow air fluctuation may cause the measured value to vary. In such cases,
covering the measuring section with an airproof cover is an effective countermeasure.
1.3.7 Waterproof and Explosionproof
The Products are not intended for use in areas where explosion protection is required. Do
not use the Products in locations where flammable gases or other explosive atmospheres
exist.
The Products are not waterproof. Do not use the Products in locations where liquids may
splash or flow into the Products.
1.3.8 Actions in case of abnormality
In the following cases, turn the power OFF, immediately. Use of the Product under
abnormal conditions may result in malfunction.
・When abnormal sounds, strange smells, or smoke is detected.

14
・If the power cord is damaged.
・If water or other liquid is spilled on the Product.
1.3.9 Repair
For repair, please contact our local sales office.
・When water or foreign matter gets inside the main unit
・When the product is damaged due to being dropped or external impact.
・When there is a strange odor due to smoke emission
1.3.10 Disposal of this Product
When disposing of the Product, treat it as industrial waste. Please follow in accordance with
laws and regulations or by other appropriate methods. We do not collect the Product for
purpose.
Please dispose of all materials used to package this product in accordance with the law or by
other appropriate methods. We do not collect these materials for the purpose.
