*1 For details on the measurement range, see page 1-13 (when the sampling cycle is between 2.55 and 10 µs).
*2 This value was taken when measuring a KEYENCE standard target (white diffuse object) in standard mode.
*3 These values were taken when measuring a KEYENCE standard target (white diffuse object) at a reference distance and with the number of averaging measurements set to 16, 384. The value in the parentheses is a typical e x ample when measured with 65, 536 averaging measurements.
