2. Safety Precautions

2.1 Environmental Safety

Do not use the equipment in environments that are flammable, explosive, high-temperature, high-humidity, high-pressure, or dusty, to prevent short circuits, corrosion, or performance failures.

Avoid placing the device in direct sunlight to prevent screen deterioration and overheating of internal components.

Stay away from environments with strong magnetic or electric fields (such as large Voltage Transformers or microwave ovens) to prevent interference that could affect the accuracy of test data.

2.2 Operational Conduct Guidelines

Do not plug in or unplug measurement probes, communication cables, or other accessories during testing to prevent damage to the connectors or data loss.

This device contains glass optical components and a touchscreen. Handle it with care when using it; do not drop or crush it, to prevent the screen from cracking or the optical components from being damaged.

When pointing the probe at the light source being measured, avoid looking directly at bright light sources—especially ultraviolet light sources—to prevent eye injury.

When performing a strobe test, you must select the continuous test mode.

To ensure accurate test results, maintain a reasonable and consistent distance from the light source during testing to avoid interference from stray light. If necessary, conduct the test in a darkroom.

Please use the standard USB cable to connect the device; using a different USB cable may cause some functions to malfunction.

2.3 Power Supply and Battery Safety

The built-in lithium-ion battery has a capacity of 4000mAh and is compatible only with the standard power adapter. Please note: Using a non-standard power adapter—especially a high-current fast-charging adapter—can easily damage the battery.

Do not use the device for extended periods when the battery level is below 15 percent. When using the device for the first time, be sure to charge it promptly when the battery level reaches 15 percent. Do not charge the battery after it has been severely discharged, as this may shorten its lifespan.

Ensure the area is well-ventilated while charging, keep the charger away from flammable materials, and unplug it promptly after charging is complete.

If the device will not be used for an extended period, fully charge it first, and then top it up every 3 months to prevent the battery from becoming damaged due to discharge.

2.4 Maintenance and Calibration Specifications

Unauthorized personnel are strictly prohibited from opening the casing for repairs, to avoid exacerbating the problem or causing personal injury.

Equipment must be sent to a laboratory accredited for spectral and photometric calibration; the recommended calibration interval is once a year.

Note 3: When saving test files to the device, only CSV files can be saved (the PDF feature is not yet fully functional). If you need a report in PDF format, you can use software on your computer to open the saved CSV file and print it as a PDF.

3.2.2 Recommended Testing Methods

All photometric data, except for luminance, are distance-dependent. For example, if you need to measure the illuminance of a light fixture at a specific distance, position the probe directly in front of the light-emitting surface of the fixture and maintain a fixed distance; changes in distance will cause the illuminance value to change. If you need to avoid interference from other light sources, you can move to a darkroom to conduct the test.

If you need to test the photometric and colorimetric parameters at a specific location and orientation indoors or outdoors, place the probe at the corresponding location, adjust it to the corresponding orientation, and then click “Test.”

Luminance data is independent of distance; the LMS-6000L is typically used to measure the luminance of displays and other devices. When using the LMS-6000L luminance meter, to avoid the influence of stray light, place the black sleeve at the front of the probe in close contact with the object being measured to obtain accurate luminance readings.
