To calculate an averaged laser position

Use the Averaged laser position function to calculate an averaged position from three laser rangefinder observations. For information on measuring a laser point, see To measure points using a laser rangefinder.

1. Tap and select Cogo.

2. Tap Averaged laser position.

   In the Contributing laser observations group, the three most recently measured laser points are listed.

3. If required, change the selected laser points.
4. Enter a point name and code for the new averaged position.

5. Tap Calc.

   The averaged position is calculated. To view the details for the averaged position, you may need to view the second page of the Averaged laser position screen.

   The estimated accuracy of the averaged position is shown in the horizontal RMS and vertical RMS fields. These values are calculated by determining the mean point where the three contributing points intersect, and then calculating the root mean square of the delta coordinates (horizontal) or the delta heights (vertical).
