Inside the Trimble X7: Deep Dive into Trimble X-Drive Technology 5

The X7 simplifies leveling with the automatic self-leveling process shown in the steps below.
Step 1: Random position of center unit Step 2: Center unit turns until tilt sensor is level
Step 3: Instrument rotates 180° around Hz axis Step 4: Center unit turns until tilt sensor is level for
second face reading
The system achieves survey grade tilt compensation if the instrument is setup within a working range up to 10°
from either side of its vertical axis for upright and upside down scans. Scans are leveled with survey grade
accuracy of < 3" (arc seconds) which is equivalent to 0.3mm @ 20 m. Setup within 10° is easy to achieve, but an
option to enable guide lights is available to let users know if the tripod needs to be adjusted. This process is quick
in the field and requires no expertise.
