2. Safety Information
Please read and understand all safety warnings before using this product. Failure to do so may result in injury or damage to the device.
- NOT for Human Use: This thermometer is designed for industrial and general-purpose temperature measurement and is not intended for medical use or measuring human body temperature.
- Laser Safety: This device uses a Class II laser with optical power <0.5mW and wavelength 630~670 nm.
- DO NOT look directly into the laser beam or point it at others. Direct eye exposure can cause eye damage.
- DO NOT aim the laser at reflective surfaces, as the beam could reflect into your eyes.
- Keep the device out of reach of children.
- Exercise caution when measuring hot surfaces. The thermometer measures surface temperature, and the object may remain very hot even after the reading is taken.

6.3 Laser Pointer Control
Press the Laser ON/OFF button (Part 2) to display the laser symbol on the screen and activate the laser light. Release the trigger to turn off the laser. Press the key again to make the laser symbol and laser disappear from the display.
6.4 Emissivity Adjustment
Emissivity (ε) is the ability of a material to emit thermal energy. Different materials have different emissivities. For accurate measurements, adjust the emissivity setting to match the target material. While the product is working, press the 'E/B' button (Part 4) to enter Emissivity mode. Use the 'UP' (Part 5) and 'DN' (Part 6) buttons to adjust the value from 0.1 to 1.0.

Common Emissivity Values:
| Material | Emissivity | Material | Emissivity |
|---|---|---|---|
| Asphaltum | 0.90 to 0.98 | Textile (Black) | 0.98 |
| Beton | 0.94 | Human Skin | 0.98 |
| Cement | 0.96 | Soap bubble | 0.75 to 0.80 |
| Sand | 0.90 | Charcoal (powder) | 0.96 |
| Soil | 0.92 to 0.96 | Lacquer | 0.80-0.95 |
| Water | 0.92 to 0.96 | Lacquer (reluster) | 0.97 |
| Ice | 0.96 to 0.98 | Rubber (Black) | 0.94 |
| Snow | 0.83 | Plastic | 0.85-0.95 |

6.5 Mode Functions (MAX, MIN, DIF, AVG, HAL, LAL)
Press the 'MODE' button (Part 3) to cycle through various measurement options:
- MAX: Measures the maximum temperature detected during a scan.
- MIN: Measures the minimum temperature detected during a scan.
- DIF: Calculates the difference between the maximum and minimum temperatures.
- AVG: Calculates the average temperature of all measurements taken.
- HAL (High Alarm): Sets a high-temperature alarm threshold.
- LAL (Low Alarm): Sets a low-temperature alarm threshold.
6.6 High/Low Temperature Alarm
To set a high or low temperature alarm:
- Press the 'MODE' button (Part 3) until 'HAL' (High Alarm) or 'LAL' (Low Alarm) is displayed.
- Use the 'UP' (Part 5) and 'DN' (Part 6) buttons to adjust the alarm threshold. Long press to accelerate value change.
- When the measured temperature exceeds the 'HAL' setting or falls below the 'LAL' setting, the LCD will display 'HI' or 'LO' respectively, and a buzzer will sound.

7. Measurement Principles: Distance-to-Spot Ratio (D:S)
The D:S ratio indicates how large an area the thermometer measures from a given distance. For the LC-1500, the D:S ratio is 30:1. This means that at a distance of 30 units from the target, the measurement spot diameter will be 1 unit. A higher D:S ratio allows for more accurate measurements of smaller areas from a greater distance, which is crucial for safety when measuring high temperatures.

- Testing high temperatures in industrial processes.
- Measuring water temperature.
- HVAC system diagnostics.
- Car repair and engine temperature checks.
- Monitoring temperatures in cooking, such as pizza ovens.
