Uhlalutyo lweempazamo zokulinganisa luphawu olubalulekileyo lokuqinisekisa ukuchaneka nokuthembeka kwiinkalo ezahlukeneyo, kubandakanya ubunjineli, ulwakhiwo, kunye nophando lwesayensi. Esinye isixhobo esiqhelekileyo esisetyenziselwa ukulinganisa ngokuchanekileyo yi-granite ruler, eyaziwa ngokuzinza kwayo kunye nokwanda okuncinci kobushushu. Nangona kunjalo, nokuba kukho izixhobo ezinjalo ezikumgangatho ophezulu, iimpazamo zokulinganisa zinokwenzeka, nto leyo ebangela ukuba kufuneke uhlalutyo olucokisekileyo.
Iirula zegranite zihlala zisetyenziswa kwi-metrology ngenxa yokuqina kwazo kunye nokumelana nokuguquguquka kwazo. Zibonelela ngomphezulu othe tyaba nozinzileyo obalulekileyo ekulinganiseni ngokuchanekileyo. Nangona kunjalo, kukho izinto ezininzi ezinokubangela iimpazamo zokulinganisa xa usebenzisa irula yegranite. Ezi ziquka iimeko zokusingqongileyo, ubuchule bomsebenzisi, kunye nemida yendalo yezixhobo zokulinganisa ngokwazo.
Izinto ezikwimeko-bume ezifana nokuguquguquka kobushushu kunye nokufuma zinokuchaphazela ubukhulu bomlawuli kunye nezixhobo zokulinganisa. Umzekelo, ukwanda kobushushu kunokukhokelela kutshintsho oluncinci kubude bomlawuli, okunokubangela ukufundwa okungachanekanga. Ukongeza, uthuli okanye inkunkuma kumphezulu womlawuli inokuphazamisana nenkqubo yokulinganisa, nto leyo ekhokelela kumahluko angakumbi.
Indlela yomsebenzisi ikwadlala indima ebalulekileyo kwimpazamo yokulinganisa. Uxinzelelo olungaguqukiyo olusetyenziswa ngexesha lokulinganisa, ukulungelelaniswa okungafanelekanga kwesixhobo sokulinganisa, okanye iimpazamo ze-parallax zonke zinokuba negalelo ekungachanekini. Ke ngoko, kubalulekile ukuba abasebenzisi baqeqeshwe kwiindlela ezifanelekileyo zokulinganisa ukuze kuncitshiswe ezi mpazamo.
Ukuze kwenziwe uhlalutyo olupheleleyo lweempazamo zokulinganisa irula yegranite, umntu kufuneka aqwalasele zombini iimpazamo ezicwangcisiweyo nezingaqhelekanga. Iimpazamo ezicwangcisiweyo zihlala zichongwa kwaye zilungiswe, ngelixa iimpazamo ezingaqhelekanga zifuna iindlela zezibalo ukuze kulinganiswe impembelelo yazo ekuthembekeni kokulinganisa.
Ukuqukumbela, nangona iirula zegranite ziphakathi kwezixhobo ezithembekileyo zokulinganisa ngokuchanekileyo, ukuqonda nokuhlalutya iimpazamo zokulinganisa kubalulekile ekufezekiseni inqanaba eliphezulu lokuchaneka. Ngokujongana neemeko zokusingqongileyo, ukuphucula iindlela zomsebenzisi, kunye nokusebenzisa iindlela zezibalo, umntu unokunciphisa kakhulu iimpazamo zokulinganisa kwaye aphucule ukuthembeka kweziphumo ezifunyenwe ngeerula zegranite.
