6. Operating Instructions
6.1 Power On/Off
- Power On: Press the MEAS button once to turn on the device.
- Power Off: Long press the CLEAR / OFF button to turn off the device. The device will also automatically power off after 150 seconds of inactivity.
6.2 Unit Switching
To change the measurement unit (meters, inches, feet):
- Long press the UNIT button to cycle through M (meters), In (inches), Ft (feet), and Ft+In (feet and fractional inches).

6.4 Single Distance Measurement
- Point the laser at the target surface.
- Press the MEAS button once. The measured distance will appear on the display.
6.5 Continuous Measurement (Tracking)
- Press the MEAS button and hold it for approximately 2 seconds. The device will enter continuous measurement mode.
- Move the device to track distances. The display will update in real-time, showing current, minimum, and maximum values.
- Press the MEAS button again to exit continuous measurement mode.
6.6 Area Measurement
- Press the Function button until the area icon (rectangle) appears on the display.
- Measure the first side (length) by pressing MEAS.
- Measure the second side (width) by pressing MEAS again.
- The calculated area will be displayed.
6.7 Volume Measurement
- Press the Function button until the volume icon (cube) appears on the display.
- Measure the length by pressing MEAS.
- Measure the width by pressing MEAS.
- Measure the height by pressing MEAS.
- The calculated volume will be displayed.
6.8 Pythagorean Measurement
This mode allows indirect measurement of height or distance using the Pythagorean theorem.
- Press the Function button until a Pythagorean icon appears (there are typically 3 types: 2-point height, 3-point height, 3-point partial height). Select the desired mode.
- Follow the on-screen prompts to measure the required sides (hypotenuse, base, etc.) by pressing MEAS for each segment.
- The calculated indirect measurement will be displayed.
