The most common types of environments where light meters are used are:
• Warehouses and factories
• Commercial office buildings
• Hotels and restaurants
• Public buildings
• Schools and other educational buildings
• Libraries
• Museums and art galleries
• Hospitals and other healthcare buildings
• Garages and car parks

• Building security
• Photography and video

Approved according to JIS C1609: 1993 and CNS 5519 general A class specifications

• Light meter
• User manual

When using this light meter, light levels are measured by either using a lux scale or footcandles scale for measurement

When the meter is not in use, keep the cap of the light sensor in position to avoid the photo diode wearing out and to prolong the accuracy of the meter
