Accuracy
The similarity of a distance measured by the tablet with the actual distance.
Cursor Eccentricity
How much the electrical center varies from the crosshair center as the cursor is rotated
through 360 degrees.
Jitter
Repeatability error of short duration caused by electrical noise.
Proximity
Greatest distance above the drawing area that the pointing tool can be raised and still be
sensed by the tablet.
Repeatability
How closely you receive the same coordinates from the repeatedly locating the point.
Repeatability takes temperature range and jitter into consideration.
