5.2 전원 켜기/끄기

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. 사용 설명서

6.1 측정하기

1. 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.
2. Press and hold the measurement trigger. The laser will activate, and the current temperature will be displayed on the LCD screen.
3. 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.

6.3 방출률 조정

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.

1. 를 누르세요 방법 button to cycle through settings until 'EMS' (Emissivity) is displayed.
2. Use the Up/Down arrow buttons to adjust the emissivity value.
3. 를 누르세요 방법 버튼을 다시 눌러 확인하고 종료합니다.

6.4 Using MAX/MIN/AVG Modes

These modes are useful for monitoring temperature fluctuations over time.

1. While holding the measurement trigger, press the 방법 button repeatedly to cycle through MAX (Maximum), MIN (Minimum), and AVG (Average) display modes.
2. The corresponding icon will appear on the screen, showing the respective temperature value recorded during the current measurement session.
