When testing directly with the LS252D, the workpiece should have a minimum mass of 5kg and a minimum thickness of 25mm.\u003c\/p\u003e\n\n\u003cp\u003eSmaller or lighter parts must be rigidly coupled to a stable support before testing. After proper coupling, the workpiece should have a minimum thickness of 3mm. Correct surface preparation, stable support and perpendicular probe contact are important for obtaining reliable results.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Choose the Linshang LS252D?\u003c\/h3\u003e\n\n\u003cp\u003eThe LS252D combines an integrated Impact Device D, automatic direction compensation and multiple hardness conversions in a highly portable instrument.
