*1 All are calculated at F.S. = (±250 mm ±9.84" ).
*2 “High accuracy range” and “long range” refer to the linearity when those ranges are used.
*3 This value was taken when measuring a KEYENCE standard target (ceramic) in standard mode.
*4 These values were taken when measuring a KEYENCE standard target (SUS) at a reference distance and with the number of averaging measurements set to 4,096
