To measure points using a laser rangefinder

To measure points or distances using a laser rangefinder connected to the controller, first configure the laser rangefinder in your survey style. For more information, refer to the Trimble Access Help.

When measuring laser points, Trimble recommends measuring three laser points for each point on the pipeline you want to measure, and then computing an averaged laser position.

  1. Tap and select Measure / Measure laser points.
  2. Enter the point name and a code for the point.
  3. In the Start point field, do one of the following:
    • Select the point you are measuring the laser point from.
    • Measure a new point using the connected GNSS receiver. To do this:
      1. Select Measure in the Start point field.
      2. Enter the details for the point and then tap Measure.

      3. Tap Store.

        The software returns to the Measure laser points screen and the point you just measured is selected in the Start point field.

  4. Enter the laser height and the target height.
  5. Tap Measure.

  6. Use the laser rangefinder to measure the distance to the target.

    The details for the measurement appear in the Measure laser points screen.

  7. Tap Store.
  8. Move to the next start position, and repeat steps 3 through 8. Repeat so that you have recorded three laser points to the target from three different start positions.

To compute an averaged position from the three laser points, see To calculate an averaged laser position.
