Tractor position icon is far above or below the surface.
Symptoms:
When implementing the position icon appears to be a long way above or below the surface (the tractor icon will normally rise to surface height if it is below the surface, but as-applied cuts will be far too deep).
Cause:
The zero value has been incorrectly set, or the base station elevation has changed since zeroing.
Solutions:
- Re-zero the T3RRA software
- Check to see that the base station coordinates have not changed. If they have, return them to the original coordinates (latitude, longitude, height).
- Be sure to save your project if you believe you will need to finish implementation at a later date in order to retain the zero value.
