*1 The values in brackets are measured in ultra-thin mode.
*2 A ±2σ margin of error when measuring a ø10 mm rod in the centre of the measurement area using outer diameter mode with the average measurement number set as 2048 times.
*3 Margin of error when a moving ø10 mm rod is measured in the 10 mm × 20 mm measurement area using outer diameter mode.
*4 The sampling cycle is changed by the number of OUT set, and by the use of the mutual interference prevention function.
*5 The value of ±2 when the outer diameter of a rod o10 mm is measured at the center of the measuring area while the number of averaging measurements is set to 512.
