3.3 Measurement Modes

The PREXISO P80GD offers 6 key measurement functions:

• Single Measurement: For a quick distance reading.
• Continuous Measurement (Min/Max): Tracks the minimum and maximum distances as you move the device, useful for finding precise points.
• Area Measurement: Calculates the area of a rectangular space by measuring two sides.
• Volume Measurement: Calculates the volume of a space by measuring three dimensions (length, width, height).
• Pythagorean Measurement (2-Point): Indirectly measures height or distance using two measurements and the Pythagorean theorem.
• Pythagorean Measurement (3-Point): Indirectly measures height or distance using three measurements for more complex scenarios.
