*1 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.
*2 Margin of error when a moving ø10 mm rod is measured in the 10 mm × 10 mm measurement area.
*3 The sampling cycle is changed by the number of OUT set, and by the use of the mutual interference prevention function.
