I have had this happen and have corrected the error with a calibration. 
In my case it didn't seem to be a permanent error and I have gone years 
without having to calibrate.

The document LVB Tracker PCB Version 1-9.doc has instructions on how to 
calibration the controller.

I have sent you a copy of the document directly.
