6.4 Basic Measurement (Single Distance)

1. Ensure the device is powered on.
2. Point the laser at the target surface.
3. Press the ON / READ button once. The measured distance will be displayed.

6.5 Continuous Measurement (Min/Max)

This mode is useful for finding the shortest or longest distance from a fixed point.

1. Press and hold the ON / READ button for 2 seconds. The device will start continuous measurement.
2. Slowly sweep the laser across the desired area. The display will show the current, minimum, and maximum measured distances.
3. Press the ON / READ button again to stop continuous measurement.

6.6 Area Measurement

1. Press the Area/Volume/Pythagorean button once to enter Area measurement mode. A square icon will appear on the display.
2. Measure the length: Press ON / READ.
3. Measure the width: Press ON / READ.
4. The device will automatically calculate and display the area.

6.7 Volume Measurement

1. Press the Area/Volume/Pythagorean button twice to enter Volume measurement mode. A cube icon will appear on the display.
2. Measure the length: Press ON / READ.
3. Measure the width: Press ON / READ.
4. Measure the height: Press ON / READ.
5. The device will automatically calculate and display the volume.

6.8 Pythagorean Measurement (Indirect Measurement)

This mode allows for indirect measurement of heights or distances using the Pythagorean theorem.

6.8.1 2-Point Pythagorean Measurement (Height)

1. Press the Area/Volume/Pythagorean button three times. The display will show a right-angle triangle icon with two sides to be measured.
2. Measure the hypotenuse (distance from device to top of object): Press ON / READ.
3. Measure the base (distance from device to bottom of object, ensuring the device remains level): Press ON / READ.
4. The device will calculate and display the height.

6.8.2 3-Point Pythagorean Measurement (Height)

1. Press the Area/Volume/Pythagorean button four times. The display will show a right-angle triangle icon with three sides to be measured.
2. Measure the first hypotenuse (distance from device to top of object): Press ON / READ.
3. Measure the second hypotenuse (distance from device to middle point of object): Press ON / READ.
4. Measure the base (distance from device to bottom of object, ensuring the device remains level): Press ON / READ.
5. The device will calculate and display the height.

6.9 Addition and Subtraction

You can add or subtract measurements from each other.

1. Perform a measurement.
2. Press the +/- UNIT button once for addition (+) or twice for subtraction (-).
3. Perform the next measurement.
4. The result of the addition or subtraction will be displayed.

6.10 Data Storage and Recall

The device can store up to 20 measurement records.
