When all of the initialization items are ticked, the receiver prompts “Tilt compensation started” and the
tilt survey icon becomes illuminated. This means that the tilt survey initialization is now complete and
you can perform the tilt survey on the receiver.
Notice:
1. Make sure the pole height is consistent with the set pole height before
the tilt survey.
2. When turning on the Tilt Survey switch, you will need to complete the initialization
operation before normal use.
3. To meet most users’ operational needs, the maximum measurement angle of the
tilt survey is 70°.
4. To ensure measurement accuracy, do not turn the device quickly during the
measurement process.
5. Data quality is not as good in an occluded environment. If accuracy requirements
are high, please try to use this function in an open environment.
6. When you enter the tilt survey for the first time every 7 days, you need to
complete the static calibration according to the prompts you receive. Let the device
stand for about 10 seconds to complete this.
