To perform self calibration you need to have a reference test block.  Portable hardness tester blocks are special and have a surface that is machined and polished.  The blocks have a weight of about 3kg and are about 55mm thickness.  This ensures that an accurate result is achieved.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAnother benefit of having a reference test block is that when unexpected results are obtained you can use the tester on the test block to verify the accuracy of the tester.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe test block have their harndess inscribed on them in the scale of HLD.  If using a different scale the reference value will be different.  We supply our test blocks with the correct value for the scale of the tester used.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp id=\"product_reference\"\u003e\u003cspan class=\"editable\"\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/form\u003e","brand":"testequipnz","offers":[{"title":"Default Title","offer_id":53843907805552,"sku":null,"price":295.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1013\/8900\/9264\/files\/lht-test-block.jpg?v=1779962374"}],"url":"https:\/\/testequip.co.nz\/collections\/test-blocks-and-indenters.oembed","provider":"testequipnz","version":"1.0","type":"link"}
