* HandPunch Calibration values

R and C values represent the HandPunch sensor image alignment. Acceptable values should be between +2 and -2, with zero being ideal. If your HandPunch shows values outside of this range then HandPunch has a problem with hand recognition and may need to be repaired.

E value represents HandPunch sensor image quality. Acceptable value is between 100 and 120, 100 being ideal. If E value is above 120, your HandPunch may produce unreliable hand images when user registers. The HandPunch can be cleaned to improve its functionality.
