5. การตั้งค่า

5.1. การติดตั้งแบตเตอรี่

The Testo 810 requires 2 AAA batteries (included).

1. Locate the battery compartment cover on the rear of the instrument.
2. เลื่อนหรือปลดคลิปฝาครอบเพื่อเปิดช่อง
3. Insert the 2 AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
4. ปิดฝาช่องใส่แบตเตอรี่ให้แน่น

6. การดำเนินการ

6.1. เปิด/ปิดเครื่อง

• การเปิดเครื่อง: กดปุ่ม ⏻ button. The display will illuminate and show current readings.
• วิธีปิด: กดค้างไว้ ⏻ button until the display turns off. The instrument also features an auto-off function to conserve battery life.

6.2. Taking Measurements (IR and Ambient)

The Testo 810 simultaneously measures both surface and air temperatures.

1. ตรวจสอบให้แน่ใจว่าเครื่องมือเปิดอยู่
2. Point the infrared sensor (at the top of the device) towards the surface you wish to measure. The 1-point laser will indicate the center of the measurement spot.
3. The IR temperature will be displayed in the larger digits, while the ambient air temperature will be shown in smaller digits.
4. For accurate IR readings, ensure the distance to the object is appropriate for the 6:1 optics ratio (e.g., at 6 inches distance, the measurement spot is 1 inch in diameter).

6.3. Adjusting Emissivity (ε)

Emissivity is crucial for accurate infrared temperature measurement. Different materials have different emissivity values. The Testo 810 allows adjustment from 0.10 to 1.00.

1. With the instrument on, press the โหมด button repeatedly until the emissivity symbol (ε) appears on the display.
2. ใช้ ▲ button to adjust the emissivity value. Refer to standard emissivity tables for common materials.
3. กดปุ่ม โหมด button again to confirm the setting and return to measurement mode.

6.4. Hold and Min/Max Functions

• ฟังก์ชั่นค้างไว้: During measurement, briefly press the โหมด button. The current readings will be frozen on the display, indicated by a 'Hold' symbol. Press โหมด again to resume live measurement.
• Min/Max Values: ในขณะที่อยู่ในโหมดการวัด ให้กดปุ่ม โหมด button repeatedly to cycle through the minimum (Min) and maximum (Max) recorded temperatures for both IR and air. The display will show 'Min' or 'Max' accordingly.
• Delta T (∆T): กด . ต่อไป โหมด ปุ่มที่จะ view the temperature difference between the IR surface and ambient air.

7. การบำรุงรักษา

7.1. การทำความสะอาด

To ensure accurate readings and prolong the life of your instrument:

• Wipe the instrument casinจีกับโฆษณาamp ผ้า ห้ามใช้สารทำความสะอาดที่มีฤทธิ์กัดกร่อนหรือตัวทำละลาย
• Carefully clean the infrared lens with a soft, lint-free cloth or a lens cleaning wipe. Avoid touching the lens directly with fingers.

7.2. การเปลี่ยนแบตเตอรี่

When the battery indicator shows low power, replace the batteries as described in Section 5.1. Always use fresh AAA alkaline batteries.

7.3. การจัดเก็บ

When not in use, store the Testo 810 in its protective cap in a dry, dust-free environment within the specified operating temperature range.
