3.2 Battery Installation

The device requires 1 Lithium Metal battery (included). Locate the battery compartment, typically on the side or back of the unit. Insert the battery, ensuring correct polarity. Close the battery compartment securely.

3.3 Power On/Off

Press the 'ON/Hold' button to power on the device. The display will illuminate, showing the measurement parameters. To power off, press and hold the 'ON/Hold' button until the display turns off.

4. Operating Instructions

4.1 Taking a Measurement

Ensure the meter is powered on.
Insert the material (e.g., window film, glass) into the 8mm test aperture. Ensure the material is fully inserted and flat within the slot.
The meter will instantly display the VLT (Visible Light Transmittance), UVR (UV Rejection), and IRR (IR Rejection) values on the screen.

4.2 Data Lock Function

To lock the displayed measurement data, press the 'ON/Hold' button briefly while the material is still in the test aperture. The 'HOLD' indicator will appear on the screen. You can then remove the material, and the readings will remain on the display until the button is pressed again or the device is powered off.

4.3 Dynamic Self-Calibration

The LS162/LS162A features dynamic self-calibration, which aids in maintaining data stability and accuracy during continuous testing. No manual calibration is typically required for standard operation.

4.4 Understanding Readings

VLT (Visible Light Transmittance): Indicates the percentage of visible light that passes through the material.
UVR (UV Rejection): Indicates the percentage of ultraviolet light (at 365nm) that is blocked by the material.
IRR (IR Rejection): Indicates the percentage of infrared light (at 940nm for LS162, 1400nm for LS162A) that is blocked by the material.

5. Maintenance

Cleaning: Use a soft, dry cloth to clean the meter's exterior. Do not use abrasive cleaners or solvents. Keep the test aperture free of dust and debris.
Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. When not in use for extended periods, remove the battery to prevent leakage.
Handling: Avoid dropping the meter or subjecting it to strong impacts, as this may damage internal components.

6. Troubleshooting

No Display/Power: Check if the battery is correctly installed and has sufficient charge. Replace the battery if necessary.
Inaccurate Readings: Ensure the test aperture is clean and free of obstructions. Verify that the material is inserted correctly and flat. The device performs dynamic self-calibration, but if issues persist, contact customer support.
Display Freezes: If the display freezes, try pressing the 'ON/Hold' button to release the data lock. If it remains frozen, power off the device and restart it.
