Figure 4: The device supports both front and rear measurement reference points for flexibility.
5.4. Pengukuran Berterusan (Min/Maks)
This mode allows for dynamic measurement, displaying the minimum and maximum distances as you move the device. This is useful for finding the shortest or longest distance to a target.
- Tekan ke MEAS button (or the button with multiple squares icon) repeatedly until the continuous measurement icon appears.
- Tekan ON/READ untuk memulakan pengukuran berterusan.
- Move the device slowly. The display will show real-time, minimum, and maximum distances.
- Tekan ON/READ sekali lagi untuk berhenti.

Figure 5: Continuous measurement mode displays minimum and maximum distances, useful for scanning areas.
5.5. Area, Volume, and Pythagorean Measurement
The device supports various advanced measurement functions:
- Pengukuran Kawasan: Tekan ke MEAS button until the area icon (rectangle) appears. Measure the length and width sequentially. The device will calculate and display the area.
- Pengukuran Isipadu: Tekan ke MEAS button until the volume icon (cube) appears. Measure length, width, and height sequentially. The device will calculate and display the volume.
- Pengukuran Pythagoras: Tekan ke MEAS button until the Pythagorean icon (triangle) appears. Follow the on-screen prompts to measure the required sides (hypotenuse and one leg) to indirectly calculate the third side.
