Operating Instructions
Measuring UV Power
This function measures the radiant energy power density in microwatts per square centimeter (uW/cm²).
Image: The Linshang LS123 UV Power Meter displaying a UV power reading of 2383 µW/cm² and a UV blocking rate of 81.1%, indicating its capability to show both measurements simultaneously.
- Press the Power button (⏻) to turn on the device.
- Point the photosensitive aperture (sensor) directly towards the UV light source you wish to measure.
- The instrument will display the UV power value in real-time on the screen in µW/cm².
Measuring UV Blocking Rate
This function determines the percentage of UV light blocked by a material.
Image: The Linshang LS123 UV Power Meter displaying a UV blocking rate of 99.8% with the 'HOLD' indicator, demonstrating its ability to measure and hold the blocking performance of materials.
- First, measure the UV power of the light source without any material, as described in "Measuring UV Power" above.
- While the light source and the instrument's position remain unchanged, place the material (e.g., solar film) between the UV light source and the photosensitive aperture of the meter.
- Press the 0% button. The instrument will then display the UV blocking rate of the material as a percentage.
Locking Data
To hold the current measurement on the display:
- During any measurement, press the HOLD button. The displayed data will be locked.
- To unlock the data and resume real-time measurement, press the HOLD button again.
