Inside the Trimble X7: Deep Dive into Trimble X-Drive Technology 6 6 Survey grade level data provides proof against survey truth. Self-Leveling will ensure accuracy you can trust without targets or extra control on topographic surveys, floor flatness applications or when monitoring the verticality of columns or walls during construction. For example, the verticality of a 10 m building will have an error of just 0.14 mm and the floor flatness of a 20 m floor will have an error of just 0.3 mm. Without survey grade leveling, some scanners can have > 8mm error at 10 m and >17 mm error at 20m. Figure 4: Survey Grade Accuracy Self-Leveling must be enabled for in field registration. If the Trimble X7 is tilted more than 10° and up to 45° the acquired scan will be roughly leveled but not guaranteed the 3" accuracy. The scan will be flagged as "Not leveled" however the Perspective software can automatically register the scan if there is sufficient overlap with the scan you're registering to. If the instrument is tilted > 45° from either side of its vertical axis, the Perspective software will display an error message and prevent scan acquisition. When the scanner is upside down and the tilt is within a range of 10°of the vertical axis, the scan will be leveled with survey grade accuracy and flipped automatically for correct orientation. The smart self-leveling also has real time level monitoring to stop scans if tilt is disrupted during scan acquisition. Figure 5: Scanner Orientations for Self-Leveling
