2.Load kewayon aikace-aikace:
01: The Vickers hardness tester tare da nauyin 49.03 ~ 980.7N ya dace da ma'auni na ma'auni na manyan kayan aiki da zurfi mai zurfi;
02: Ƙananan nauyin Vickers hardness, gwajin gwaji <1.949.03N, dace da ma'aunin ma'auni na bakin ciki workpieces, kayan aiki saman ko coatings;
03: Micro-Vickers taurin, gwajin gwaji <1.961N, dace da ma'aunin taurin karfe da yadudduka na bakin ciki sosai.
Bugu da kari, sanye take da indenter na Knoop, zai iya auna taurin Knoop na gagajewa da kayan aiki masu wuya kamar gilashi, yumbu, agate, da duwatsu masu daraja.
Fa'idodi 3 na Vickers hardness tester:
1) Ma'aunin ma'auni yana da faɗi, kama daga ƙarfe masu laushi zuwa ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙarfe zuwa manyan ƙarfe masu ƙarfi, kuma kewayon ma'aunin ya bambanta daga ƙimar taurin Vickers kaɗan zuwa dubu uku.
2) Ƙaddamarwa ƙarami ne kuma baya lalata kayan aiki.Ana iya amfani da shi don gwajin taurin kayan aikin da ba za a iya lalacewa ba.
3) Saboda ƙananan ƙarfin gwajinsa, mafi ƙarancin ƙarfin gwajin zai iya kaiwa 10g, don haka yana iya gano wasu sirara da ƙananan kayan aiki.
4 Rashin hasara na mai gwada taurin Vickers: Idan aka kwatanta da hanyoyin gwaji na Brinell da Rockwell, gwajin taurin Vickers yana da buƙatu don santsi na farfajiyar aiki, kuma wasu kayan aikin suna buƙatar gogewa, wanda ke ɗaukar lokaci da aiki mai ƙarfi;kiyaye Gwajin taurin ya yi daidai kuma bai dace da amfani da shi ba a wurin bita ko a wurin.An fi amfani dashi a dakunan gwaje-gwaje.
