How Do I Use My Leica 3D Disto?

Using your Leica 3D Disto involves setting up the device and defining a reference coordinate system to perform accurate measurements in three dimensions, particularly during manual measurement tasks.

Getting Started with Leica 3D Disto

The Leica 3D Disto is a powerful tool for capturing 3D points, projecting layouts, and verifying dimensions. While it has various functions, a fundamental aspect of its use is performing manual measurements relative to a defined origin and coordinate system.

Setting Up the Coordinate System for Measurement

Based on the process for manual measuring, defining the coordinate system is crucial. The system establishes a reference framework (x, y, z) for all subsequent measurements.

Here's how the system is defined, according to the reference:

1. Measuring the First Point: The first point you measure establishes the origin of your coordinate system. This point is assigned the coordinates (0, 0). The reference states that this point also receives a corresponding height based on a previously measured reference height. This means the Z-axis reference is tied to an initial setup process that defines this base height.
2. Measuring the Second Point: The second point you measure is used to define the direction of the X-axis. The line connecting the first point (origin) to the second point becomes the positive direction of the X-axis in your measurement plane.

Once these two points are measured, the Leica 3D Disto establishes the full 3D coordinate system (X, Y, Z) relative to them. The Y-axis will be perpendicular to the X-axis within the horizontal plane, and the Z-axis (height) will be relative to the initial reference height established when measuring the first point.

Performing Manual Measurements

After the coordinate system is set up by measuring the first two points as described above, you can proceed with manual measurements.

• Targeting: Point the Leica 3D Disto's laser accurately at the point you wish to measure.
• Measuring: Use the device's controls (often via a separate controller or tablet interface) to trigger a measurement.
• Receiving Coordinates: The device will then provide the 3D coordinates (x, y, z) of the targeted point relative to the origin (first point) and the defined X-axis (line between the first and second point).

This process allows you to capture the precise 3D location of any point within the device's range relative to your chosen reference points.

Summary of Point Roles in System Setup

By following these steps, you establish a reliable coordinate system necessary for performing accurate manual measurements with your Leica 3D Disto, using the first two points to define the fundamental reference frame.
