6.3 Reference Point Adjustment

The device can measure from either its front or rear edge. Press and hold the UNITS button to switch between front and rear reference points. An icon on the display will indicate the active reference point.

6.4 Basic Measurement (Single Distance)

1. Ensure the device is powered on.
2. Point the laser at the target surface.
3. Press the MEAS button once. The measured distance will appear on the display.

6.5 Continuous Measurement

This mode allows for dynamic measurement, displaying real-time distance as the device is moved. It also records maximum and minimum values.

1. Press and hold the MEAS button. The device will enter continuous measurement mode.
2. Move the device to measure different distances. The display will update continuously, showing current, maximum, and minimum values.
3. Press the MEAS button again to exit continuous measurement and freeze the last reading.

6.6 Area Measurement

1. Press the Function button (cube icon) once. The area icon will appear on the display.
2. Measure the first side (length) by pressing MEAS.
3. Measure the second side (width) by pressing MEAS.
4. The device will automatically calculate and display the area.

6.7 Volume Measurement

1. Press the Function button (cube icon) twice. The volume icon will appear on the display.
2. Measure the length by pressing MEAS.
3. Measure the width by pressing MEAS.
4. Measure the height by pressing MEAS.
5. The device will automatically calculate and display the volume.

6.8 Pythagorean Measurement

The MST50 supports three types of Pythagorean measurements for indirect height or distance calculations.

6.8.1 Pythagorean-1 (Indirect Height)

1. Press the Function button (cube icon) three times. The Pythagorean-1 icon will appear.
2. Measure the hypotenuse (distance from device to top of object) by pressing MEAS.
3. Measure the base (horizontal distance from device to bottom of object) by pressing MEAS.
4. The device will calculate and display the indirect height.

6.8.2 Pythagorean-2 (Indirect Height with two hypotenuses)

1. Press the Function button (cube icon) four times. The Pythagorean-2 icon will appear.
2. Measure the first hypotenuse (distance from device to top of object) by pressing MEAS.
3. Measure the second hypotenuse (distance from device to bottom of object) by pressing MEAS.
4. Measure the horizontal distance between the two points on the ground by pressing MEAS.
