5.2 Daya Hurung/Pareuman
- Pikeun ngaktipkeun, pencét tombol MEAS kancing.
- To power off, long-press the HARUS/PAreuman tombol. Alat ogé bakal otomatis pareum saatos teu aktip salami sababaraha waktos pikeun ngahémat batré.
6. Modeu Operasi
The DP20 offers a variety of measurement modes to suit different needs. Use the MODÉ tombol pikeun ningali-ningali fungsi anu sayogi.
6.1 Single and Continuous Measurement
For basic distance measurements.
- Pencét éta MEAS button once for a single measurement.
- Pencét lila MEAS button to enter continuous measurement mode, which also displays minimum and maximum distances. Press MEAS deui eureun.
6.2 Bilateral and One-Way Measurement
The DP20 allows switching between bilateral (two-way) and one-way laser measurement.
- Use the dedicated button (often labeled T/R or similar, refer to device markings) to switch between bilateral and one-way laser modes.
- Bilateral mode measures the distance between two points by positioning the device anywhere along the line.
- One-way mode measures from the device to a single target point.

6.3 Aréa jeung Pangukuran Volume
To calculate area or volume:
- Select the Area or Volume mode using the MODÉ kancing.
- Follow the on-screen prompts to take the required number of measurements (e.g., length and width for area; length, width, and height for volume).
- The device will automatically calculate and display the result.
6.4 Pangukuran Pythagoras
For indirect measurements of height or distance where direct measurement is not possible.
- Select the Pythagorean mode using the MODÉ kancing.
- Follow the on-screen prompts to take the necessary measurements (e.g., hypotenuse and one leg for height).
- The device will calculate and display the unknown dimension.
6.5 Line Segment Division (Staking Out)
This function divides a line segment into equal smaller segments, useful for tasks like installing multiple items at consistent intervals.
- Enter the Line Segment Division mode (often labeled 1/N).
- Set the number of desired segments (N).
- Measure the total length of the line. The device will then guide you to the division points.

6.6 Digital Angle Level
The integrated digital angle level provides real-time angle measurements.
- The device automatically displays the current tilt angle.
- This feature can be used in conjunction with other measurement modes for more complex calculations.
