5.2 Changing Units
Press the Unit Button (component 9) to cycle through the available measurement units: meters (m), inches (in), and feet (ft).
5.3 Single Distance Measurement
- Power on the device.
- Aim the laser at the target point.
- Press the Measurement Button (MEAS) (component 5) once. The measured distance will be displayed instantly.

5.4 Continuous Measurement (MAX/MIN)
This mode allows for dynamic measurement, displaying the maximum and minimum distances as you move the device.
- Press the Continuous Measurement Button (MAX/MIN) (component 6) once.
- Move the device slowly towards or away from the target. The display will continuously update the current, maximum, and minimum distances.
- Press the Continuous Measurement Button (MAX/MIN) again or the Measurement Button (MEAS) to stop.
5.5 Area Measurement
To calculate the area of a rectangular space:
- Press the Area/Volume/Pythagorean Button (component 2) once until the area icon (a square) appears on the display.
- Measure the first side (e.g., length) by pressing the Measurement Button (MEAS).
- Measure the second side (e.g., width) by pressing the Measurement Button (MEAS) again.
- The device will automatically calculate and display the area.
5.6 Volume Measurement
To calculate the volume of a rectangular space:
- Press the Area/Volume/Pythagorean Button (component 2) twice until the volume icon (a cube) appears on the display.
- Measure the length by pressing the Measurement Button (MEAS).
- Measure the width by pressing the Measurement Button (MEAS).
- Measure the height by pressing the Measurement Button (MEAS).
- The device will automatically calculate and display the volume.
5.7 Pythagorean Measurement
This mode allows indirect measurement of height or distance using the Pythagorean theorem.
- Press the Area/Volume/Pythagorean Button (component 2) repeatedly until the desired Pythagorean mode icon appears (e.g., a triangle with one side unknown).
- Follow the on-screen prompts to measure the required sides (hypotenuse, base, etc.) by pressing the Measurement Button (MEAS) for each segment.
- The device will calculate and display the unknown side.
