| *1 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. *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 at the reference distance with the number of averaging measurements set to 16384. The value in parentheses is a typical example of a measurement with the number of averaging measurements set to 65536 and the sampling cycle to 200 μs. *3 Use one of the following dark filters when measuring a transparent or mirror surface object: LK-H082/LK-H087: LK-F3, LK-H152/LK-H157: LK-F2 *4 Measurement range when the sampling cycle is 20 μs or more. *5 When the ambient temperature rises to 40°C 104°F or more, mount this on a metal plate before use. |
