3. After aiming in the 315° direction and squeezing the trigger, the<br />

rear panel of the ProSurvey 1000 indicates a Noise value,<br />

ranging from 0 to 9.<br />

The higher the value, the better the calibration. If the Noise<br />

value is below 5, perform the calibration again.<br />

I.3.4 Using the ProSurvey 1000 with the Asset Surveyor<br />

Software<br />

As mentioned previously, the practical accuracy of the fluxgate<br />

compass in typical field use is around ±1–2°. This yields a steady<br />

reduction in accuracy as the distance between the laser and a target<br />

point increases. At a distance of 100–200 m, the average positional<br />

error when using the ProSurvey 1000 is approximately 2 m (in<br />

addition to the error of your GPS measurement).<br />

Testing<br />

When you first connect the ProSurvey 1000 to your <strong>Trimble</strong> GPS<br />

system, test that it is correctly configured and that all components are<br />

working correctly.<br />

Select the Configuration entry from the Asset Surveyor software’s<br />
