EverTrack^TM

EverTrack^TM is a new feature included in RBS- and RBM-type scales. It is an absolute reference system that always keeps track of the position, whether powered up or not, so you will never lose your work. EverTrack^TM eliminates the need for awkward short-term battery back-up solutions.

The EverTrack^TM feature is accomplished by a reference index track in addition to the regular grating, which is a set of equal lines 20 um apart. The index track has two sets of marks, indicated by red and blue. The distance between consecutive red marks is always 1000 increments and between blue marks, 1001 increments. So, along the index track there is always a unique number of increments between a red and a blue mark. By moving the part less than an inch (25 mm), the console knows exactly where it is in absolute measure. As part zero and other references are always stored, the operator can get back to work without resetting anything at all. It does not matter if the machine has been moved during a power outage or over night, EverTrack^TM will give the right position every time.
