1. At the beginning of initialization, the pole height of the instrument should be the same as
that antenna height in the software.
2. In the process of tilt measurement, if the controller shows that “Tilt is not available, please
measure in alignment” (red), please shake RTK slightly from left to right or back to front until
the reminder disappears.
3. The controller will prompt “Tilt is not available, please measure in alignment” when the
receiver is stationary over 30 seconds or the pole hit the ground toughly.
4. The pole cannot be shaken when point is collected.
5. Initialization is required:
▪ when the RTK is turned on every time;
▪ when IMU module is turned on every time;
