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. ຄໍາແນະນໍາການດໍາເນີນງານ

6.1 ການວັດແທກ

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, ໃນໄລຍະຫ່າງ 12 ນິ້ວ, ຈຸດວັດແທກຈະມີເສັ້ນຜ່າສູນກາງ 1 ນິ້ວ.

6.3 ການປັບຄ່າ emissivity

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.
