4.3  Calculate Linearity : For the First Row0
R0avg = （ VC0 + VC1 + VC2 +- - - - - - - + VC9） ÷ 10
     R0max = The maximum voltage in Row 0
     R0min = The minimum voltage in Row 0
     R0 linear1 = ⏐ R0 max – R0 avg. ⏐ ÷ R0 avg. ∗ *
     R0 linear2 = ⏐ R0 min – R0 avg. ⏐ ÷ R0 avg. ∗ *
     R0 linear = max （R0 linear1, R0 linear2）
 
4.4  For X Coordinate Test 
Add 5 voltage between X1 and X2 touch the point C0R0 to C9R9
separay and measure the voltage from Y1 as the above drawing

C0avg = （ VR0 + VR1 + VR2 +- - - - - - - + VR9 ） ÷ 10
C0max = The maximum voltage in Column 0 
C0min = The minimum voltage in Column 0
   C0 linear1 = ⏐ C0 max – C0 avg. ⏐ ÷ C0 avg. ∗ *
   C0 linear2 = ⏐ C0 min – C0 avg. ⏐ ÷ C0 avg. ∗ *
   C0 linear = max （ C0 linear1 ,C0 linear2 ）
