5.2 Menghidupkan/Mematikan
To power on the device, simply press the measurement trigger. The device will automatically power off after a period of inactivity to conserve battery life.
6. Arahan Operasi
6.1 Mengambil Pengukuran
- Point the thermometer at the target surface. Ensure the laser pointer (if activated) is aimed at the center of the area you wish to measure.
- Press and hold the measurement trigger. The laser will activate, and the current temperature will be displayed on the LCD screen.
- Release the trigger to hold the measurement on the display. The 'HOLD' icon will appear.

6.2 Understanding Distance-to-Spot Ratio (D:S)
The DIT-220 has a Distance-to-Spot ratio of 12:1. This means that as you move further from the target, the area being measured (spot size) increases. For accurate readings, ensure the target area is larger than the spot size. For example, at a distance of 12 inches, the measurement spot will be 1 inch in diameter.

Rajah 4: Illustration of the 12:1 Distance-to-Spot ratio.

Rajah 5: Visual guide for maintaining correct measurement distance.
6.3 Melaraskan Emisiviti
Different materials emit infrared energy differently. The DIT-220 allows you to adjust the emissivity (ε) from 0.10 to 1.00 to compensate for this and achieve more accurate readings. Refer to a standard emissivity table for common materials or adjust empirically.
- Tekan ke MODE button to cycle through settings until 'EMS' (Emissivity) is displayed.
- Use the Up/Down arrow buttons to adjust the emissivity value.
- Tekan ke MODE butang sekali lagi untuk mengesahkan dan keluar.

6.4 Using MAX/MIN/AVG Modes
These modes are useful for monitoring temperature fluctuations over time.
- While holding the measurement trigger, press the MODE button repeatedly to cycle through MAX (Maximum), MIN (Minimum), and AVG (Average) display modes.
- The corresponding icon will appear on the screen, showing the respective temperature value recorded during the current measurement session.

6.5 Menukar Unit Suhu (°C/°F)
To switch between Celsius and Fahrenheit, press the °C/°F button located on the device.
7. Penyelenggaraan
7.1 Pembersihan
- Bersihkan kanta dengan lembut, damp cloth or cotton swab. Do not use abrasive cleaners or solvents.
- Lap peranti casing dengan kain lembut dan kering.

8. Penyelesaian masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Display shows 'Lo' or 'Hi' | Suhu berada di luar julat ukuran. | Ensure the target temperature is within -50°C to 530°C (-58°F to 986°F). |
| Bacaan tidak tepat | Incorrect emissivity setting; measurement distance too far/close; lens dirty. | Adjust emissivity for the target material. Maintain appropriate D:S ratio. Clean the lens. |
| Peranti tidak dihidupkan | Bateri mati atau tidak dipasang dengan betul. | Replace batteries with new AAA batteries. Check battery polarity. |
