n X-Shift、Y-shift、Theta– Presents the horizontal shift and vertical shift and
the rotated angle separately.
n High, Low – The upper and lower limit for the testing result. When the
result is laid in this range, it can be included in calculating.
n USL–The upper spec limit for calculating Cpk index.
n LSL–The lower spec limit for calculating Cpk index.
n CpkSpec–The tolerance for Cpk. It is normal when Cpk is greater than this
value; it’s abnormal when Cpk is smaller than this value.
n Never–Not to output automatically.
n By Inspection Time–Outputs data according to the assigned time
interval.(unit: hours)
n By Inspection Times–Outputs data according to the assigned number of
inspected counts.

Count The number of data calculated.
X_Max The maximum for X-shift (unit: mm)
Y_Max The maximum for Y-shift (unit: mm)
Theta_Max The maximum for Theta (unit: mm)
X_Min The minimum for X-shift (unit: mm)
Y_Min The minimum for Y-shift (unit: mm)
Theta_Min The minimum for Theta (unit: mm)
X_Average The average for X-shift (unit: mm)
Y_Average The average for Y-shift (unit: mm)
Theta_Average The average for Theta (unit: mm)
X_Sigma The sigma for X-shift (unit: mm)
Y_Sigma The sigma for Y-shift (unit: mm)
Theta_Sigma The sigma for Theta (unit: mm)
X_CpkSpec CpkSpec for X-shift
X_Cpk Cpk for X-shift
Y_CpkSpec CpkSpec for Y-shift
Y_Cpk Cpk for Y-shift
Theta_CpkSpec CpkSpec for Theta
Theta_Cpk Cpk for Theta
Missing The number of missing.
X_Position The result of X coordinate on CAD adds the average of X-shift
Y_Position The result of Y coordinate on CAD adds the average of Y-shift
Status It shows [NG] and displays yellow symbol when there’s a
[Missing] or [Cpk＜CpkSpec]. Otherwise it shows [OK].
n Show Graphic – Show the time sequence graph for selected component.
Ø You can select to display the graph of X-shift, Y-shift or Rotation.
Ø The horizontal axis presents the count and the vertical means the
result.
Ø The red line means the average.
