· Before photogrammetry, test the tilt measurement function. Measure a point and perform stake out. If the stake out accuracy is within 2cm, the tilt measurement is functioning well.
· After photogrammetry, check the accuracy. Measure the photogrammetry point again with regular tilt measurement. Use the "Great-circle distance" function to calculate the distance between the two points. If the distance is within 2.5cm, the measurement accuracy is basically acceptable. Then you can further verify using point stake out.
· Taking photos. Move around the object as the software suggests and take at least 5 photos.
· Selecting points. After taking photos, enter the photo gallery to choose and save suitable points. Note: Points with great color contrast to surrounding objects are preferred to prevent calculation failures.
· Avoid measuring in dim environments.
· Avoid measuring in extreme weather like heavy rain, dense fog, or heavy snow.
· Avoid measuring near high - rise buildings.
· Check the satellite count and differential delay. There should be over 25 available satellites, with a differential delay of no more than 3 (preferably maintained at 1). These two status can be directly viewed at the top right corner of the software.
· Check the communication connection. The photogrammetry software and receiver must communicate via Wi-Fi, which can be checked in the communication settings.
· Check the inertial navigation (IMU) status. If it's unavailable, the measurement interface will show a warning in red.
· Strong impact of the pole tip on the ground can affect the IMU data of the receiver. Walking with the pole tilted after the IMU is activated may prevent the IMU from accurately sensing the initial posture.
· Before laser measurement, test the tilt measurement function. Measure a point and then perform stake out. If the stake out accuracy is within 2cm, the tilt measurement is functioning well.
· After laser measurement, verify the accuracy. Compare the points measured with the laser with those measured using point - to - point survey. Use the "Great-circle distance" function to calculate the difference between the two points. If the difference is within 2cm, the measurement accuracy is basically acceptable. Then you can further verify using point stake out and laser stake out.

A. Check if the built-in antenna is connected.
B. Configure the radio protocol and frequency to match the base station.
C. Ensure the satellite reception environment is good.

Check if the base station is started with fixed coordinates.
If the deviation between fixed coordinates and actual coordinates is too large.
It is recommended to reacquire fixed coordinates or switch to single-point coordinates to start the base station.
The tilt is enabled, but the inertial navigation correlation has not been completed.
A. Confirm that the input pole height matches the actual pole height.
B. Rock the centering rod back and forth for 5-10 seconds.
If convergence is not completed, rotate the centering rod 90°, then rock the centering rod back and forth for 5-10 seconds.
