7. Single, Continuous, Area, Volume and Pythagorean Measurement.

7.1 Single Measurement

The operating steps are as the following:

1) Short press the button 🙏 in measuring mode and the laser will be emitted.

2) Lock the measurement target. Short press the button 📄. The distance is measured and shown in the main display area.

7.2 Continuous Measurement

Users can use this mode to find a distance point and get required data without frequent operation.

The operating steps are as following:

1) Long press the button 📋 in the measurement mode to enter continuous measurement mode. The secondary display area will show the max and min values in continuous measurement, main display area will show the current measurement value.

2) Short press the 📄 or 🕒 button to exit continuous measurement.

7.3 Area Measurement

Short press the button ☑ once, and the screen will display ■. One side of the rectangle will be flickering. Finish the following operations according to prompts.

Press the button 🔒 to measure the length.

Press the button → to measure the width.
