The device position move should be executed with auto-scale to allow for growth or shrinkage of the part. When drift is noticed, a device position move (Relocation in Insight) should be done to re-fit the tracker back into the coordinate system. These points should be checked periodically for drift. Because of these environmental effects, drift must be checked throughout the duration of a measurement job.Īt the beginning of a measurement job, several fixed reference points should be measured over the full volume of the part. Changes in temperature can affect the part being measured, the floor, the tracker stand and the Tracker. ![]() This drift can be caused by vibration or temperature changes in the environment. Long duration measurements, jobs that last more than two hours, typically experience global drift. ![]() A detailed report of the results can be viewed and saved. These tests provide a pass/fail result that is based on the Tracker specifications. Some operators who ship the tracker to each inspection location may choose to go straight to the Advanced Tab of CompIT and run a full Pointing Compensation continuing onto the Squareness portion of the compensation despite the passing results up to that point to re-optimize the Squareness parameter for any small changes that may have occurred during transit.Ī Pointing Interim Test or Backsight Check can be run at any time to determine whether the tracker is measuring within specification. Its changes are typically a result of shock, vibration or shipping. The Squareness parameter is a very stable parameter and does not change with temperature. If the Pointing Compensation is not bringing the tracker into tolerance after the 6 points are measured, then it will recommend continuing onto the Squareness Compensation, which consists of a few more points on the floor. For the highest accuracy, the compensation can be performed even if the interim test passes. The interim test will report whether the Tracker is within specification. Pointing CompIT should be run immediately before starting a measurement job. The compensation points are at 2, 4 and 6 meters and will bring the Tracker into specification at all ranges.įor the highest accuracy at ranges over 20 meters, Pointing CompIT can be customized to use the maximum range required for the measurement job. The standard Pointing CompIT takes three interim test points to check accuracy and six points to compensate. ![]() Pointing CompIT allows you to check the accuracy of the tracker and compensate if necessary. 3D Hand Held Scanner - Freestyle3D Objects
