1. Introduction
The Linshang LS116 light transmittance tester is a professional instrument designed for accurately measuring the light transmittance of various uniform light-transmitting materials. Its advanced parallel light path design allows for precise measurements, even on materials with significant thickness. This device is engineered to meet stringent metrology standards, ensuring reliable and accurate results for applications involving glass, solar film, laminated glass, PC plastic, and other optical products.
2. What's in the Box
Upon opening the package, please verify that all components are present and in good condition:
- LS116 Meter
- Probe
- User Manual
- Warranty Card
- Holder
- Four AAA batteries
3. Setup
Before first use, install the four AAA batteries into the battery compartment located on the back of the LS116 meter. Ensure correct polarity. Once batteries are installed, connect the probe to the main meter unit via the cable. The device is now ready for initial power-on.
4. Operating Instructions
The LS116 offers versatile measurement capabilities for various light-transmitting materials.
4.1 Power On and Warm-up
Press the power button to turn on the device. The meter will display a "WARM-UP" message and a percentage. Allow the device to complete its warm-up cycle until it displays 100.00% or a stable reading, indicating it is ready for measurement.
4.2 Measurement Methods
The LS116 supports two primary measurement methods:
- Fixed-Point Measurement: Use the provided holder for stable, precise measurements in a fixed laboratory or factory setting.
- Field Measurement: The compact design allows for on-site measurements, such as testing automotive front glass or other installed materials.
4.3 Testing Transmittance
Place the material to be tested between the light source and the receiver of the probe. Ensure the material completely covers the light path. The measurement will be displayed instantly on the meter's screen.
4.4 High and Low Transmittance Materials
The LS116 is capable of testing a wide range of materials, from highly transparent to very low transmittance. It can measure high-transmittance samples up to 99.8% and low-transmittance materials with a resolution of 0.001%.
4.5 Large Thickness Materials
Thanks to its parallel light path and receiver spotlight design, the LS116 can effectively measure large thickness materials, up to 100mm thick, without compromising accuracy.
4.6 Diverse Material Testing
The LS116 is suitable for testing the transmittance of various uniform light-transmitting materials, including but not limited to:
- Transparent glass
- Laminated glass
- Insulated glazing
- Solar film
- Coated materials
- Organic material panels
4.7 Accuracy and Certification
The LS116 boasts an accuracy of ±1%, ensuring reliable and precise measurements. This accuracy is verified through testing by metrology institutes, providing confidence in its performance.
