^*1 Measurement range when the sampling cycle is 20 µs or more.
^*2 This value is obtained when the KEYENCE standard target (White diffuse workpiece or workpiece with a metal mirror surface only for the LK-H008/LK-H008W) is measured in the normal measurement mode.
^*3 This value is obtained when the KEYENCE standard target (White diffuse workpiece or workpiece with a metal mirror surface only for the LK-H008/LK-H008W) is measured at the reference distance with the number of averaging measurements set to 16384. The value in parentheses is a typical e x ample of a measurement with the number of averaging measurements set to 65536 and the sampling cycle to 200 µs.
^*4 When the ambient temperature rises to 40 °C or more, mount this on a metal plate before use.
