6. 操作手順

6.1測定を行う

1. 温度計を対象物に向けます。
2. Press and hold the trigger to activate the laser pointer and begin measurement. The temperature reading will appear on the LCD display.
3. Release the trigger to hold the measurement on the display.

6.2 放射率の調整

Emissivity (ε) is crucial for accurate temperature readings. Different materials have different emissivities. The default setting is 0.95, suitable for most organic materials and painted surfaces.

• Press the "SET" button to enter emissivity adjustment mode.
• Use the Up/Down arrows (often combined with the laser button or separate buttons) to adjust the emissivity value from 0.1 to 1.0.
• Press "SET" again or wait a few seconds for the setting to be saved.

6.3 距離対スポット比（D:S）

The D:S ratio indicates the size of the area being measured relative to the distance from the object. This model has a D:S ratio of 12:1, meaning that at 12 inches from the target, the measurement spot diameter is 1 inch.

• To ensure accurate readings, make sure the target area is larger than the spot size at your measurement distance.
• Measuring closer to the object will result in a smaller spot size and more precise measurement of a specific area.

6.4 単位変換（°C/°F）

The device supports both Celsius and Fahrenheit temperature units. Refer to the device buttons (often labeled "°C/°F" or similar) to switch between units.

7. メンテナンス

• クリーニング： 柔らかくてamp デバイスを清掃するための布asing. 研磨剤入りの洗剤や溶剤は使用しないでください。
• レンズケア: The infrared lens is the most delicate part. Clean it gently with a soft cloth or cotton swab and rubbing alcohol, or lens cleaner. Avoid touching the lens directly.
• ストレージ： 温度計は直射日光や極端な温度を避け、乾燥した涼しい場所に保管してください。
• バッテリー交換: 正確な測定を行うために、ディスプレイに電池残量低下インジケーターが表示されたら電池を交換してください。
