Coordinate stability3Coordinate accuracy3.Coordinate accuracyWacom will provide FW data and evaluation report.Calibration work will take approximately 1-2 weeks.C lib i k h i US$1 200 lib iCalibration work charge is US$1,200 per calibration.27 • 30.10.2007 • Wacom Confidential
9-2. System CalibrationEM noise environment•EM noise which mimic pen signal can cause digitizer malfunction. •Wacom will search the EM noise and measure the level•Wacom will search the EM noise and measure the level.28 • 30.10.2007 • Wacom Confidential
9-3. System CalibrationCoordinate stabilityEM noise can cause vibration of coordinate detected by digitizer (jitter). Wacom quantifies the level of jitter by take 100 coordinate data at each spot and calculating standard deviation and max deviation from mean location.29 • 30.10.2007 • Wacom Confidential
9-4. System CalibrationC di t b f lib tiCoordinate accuracy before calibrationMetal parts or EM noise will disturb digitizer signal and can cause the deterioration of digitizer accuracy.Digitizer signal can be compensated by calibration up to certain level.Wacom measures the accuracy before and after calibration.30 • 30.10.2007 • Wacom Confidential
