5.2 Basic Measurement Modes
- Single Distance Measurement: Press the measurement button once to activate the laser, then again to take a single measurement.
- Continuous Measurement (Tracking): Hold the measurement button to continuously measure distances, useful for finding minimum/maximum values or scanning.
- Area Measurement: Measure two sides to calculate the area.
- Volume Measurement: Measure length, width, and height to calculate volume.
5.3 Advanced Measurement Functions
- Dual Visual Alignment: The D9 Pro features unique bilateral laser reference lines, ensuring 100% co-axial alignment. This provides a clear visual reference for horizontal or inclined alignment and marking.
- Point-to-Point (P2P) Technology: This function allows you to measure the distance between two points from a single remote location, ideal for hard-to-reach areas or complex situations like measuring inclined frames or ceilings.
- Live Angle Display: The D9 Pro features a 360° angle sensor and an innovative live rotation angle display, providing real-time feedback and confirmation of angle measurements on any surface (inclined, vertical, horizontal).
- Stake-out Function: Use this mode to mark specific intervals or points along a measured line.
- Automatic Rotating Display: The screen automatically rotates for easy viewing in any orientation.
- Integrated Flashlight: The 90 LM LED flashlight can be used independently of the measurement functions.
