Figure 2: Instructions for changing measurement units and setting reference points. Long-press the UNIT button to cycle through units (m, ft, in, ft+in). Short-press the UNIT button to change the reference point between front and back.
2.4 යොමු ලක්ෂ්ය සැකසුම
The default reference point is the end of the device. To change the reference point (front or back), short-press the ඒකකය button. This is crucial for accurate measurements depending on where the device is placed.
2.5 Buzzer On/Off
To turn the buzzer sound on or off, long-press the sound button. A speaker icon with a cross will appear on the display when the buzzer is off.
2.6 Smart APP Connectivity
The MILESEEY D5-APP-US syncs with the "Smart Life" app for real-time data transfer and storage of up to 1000 sets. The app allows you to create 2D floor plans or annotate images with measurements.

3.1 තනි මිනුම්
ඔබන්න MEAS ලේසර් සක්රිය කිරීමට බොත්තම වරක් ඔබන්න. තනි දුර මිනුමක් ගැනීමට එය නැවත ඔබන්න. ප්රතිඵලය තිරය මත දිස්වනු ඇත.
3.2 අඛණ්ඩ මිනුම්
දිගු-ඔබන්න MEAS button for 2-3 seconds to enter continuous measurement mode. The device will continuously measure and display the maximum, minimum, and current values. Short-press MEAS again to stop and display the final data.
3.3 ප්රදේශය මැනීම
ඔබන්න මාදිලිය button until the area icon appears. Take two consecutive measurements (length and width). The device will automatically calculate and display the area.
3.4 පරිමාව මැනීම
ඔබන්න මාදිලිය ශබ්ද නිරූපකය දිස්වන තුරු බොත්තම ඔබාගෙන සිටින්න. අඛණ්ඩව මිනුම් තුනක් (දිග, පළල සහ උස) ගන්න. උපාංගය ස්වයංක්රීයව පරිමාව ගණනය කර පෙන්වනු ඇත.
3.5 Pythagorean Measurement (Indirect Length)
The device supports 2-point and 3-point Pythagorean measurements for indirect length calculations. Press the මාදිලිය button until the desired Pythagorean icon appears. Follow the on-screen prompts to take the required measurements. For best accuracy, especially with handheld measurements, using a tripod is recommended.
Video 2: This video provides a detailed guide on various measurement methods for a laser measuring tool, including single, continuous, area, volume, and Pythagorean measurements. This is directly applicable to the MILESEEY D5-APP-US.
3.6 එකතු කිරීම සහ අඩු කිරීම
To add or subtract measurements, take the first measurement, then press the + or - button. Take the next measurement, and the result of the operation will be displayed. This function can be used for length, area, and volume calculations.
3.7 ඉලෙක්ට්රොනික කෝණ සංවේදකය
The device features an advanced electronic angle sensor that provides real-time angle display. This allows for faster and more accurate measurements compared to traditional bubble levels, especially for indirect height and distance calculations.

4. නඩත්තු කිරීම
4.1 Accuracy Check
To check the accuracy of the measuring tool, select a permanently unchangeable indoor measuring section (approx. 9.8 to 32 ft or 3 to 10 m long) with weak backlighting and a smooth, reflective target area (e.g., a white-painted wall). Measure the distance 10 times in succession. The deviation of individual measurements from the average value must not exceed ±0.12 in (±2 mm). Record these measurements to compare accuracy at a later date.
4.2 සාමාන්ය රැකවරණය
Keep the device clean and dry. Avoid exposing it to extreme temperatures or direct sunlight for extended periods. The device has an IP54 rating, indicating protection against dust and splashing water, but it is not fully waterproof.
