Ukuhlaziywa kwamaphutha okulinganisa kuyisici esibalulekile sokuqinisekisa ukunemba nokuthembeka emikhakheni ehlukahlukene, okuhlanganisa ubunjiniyela, ukwakhiwa, kanye nocwaningo lwesayensi. Ithuluzi elivamile elisetshenziselwa ukulinganisa okunembile yi-granite ruler, eyaziwa ngokuqina kwayo kanye nokukhula okuncane kokushisa. Kodwa-ke, ngisho nangamathuluzi anjalo asezingeni eliphezulu, amaphutha okulinganisa angenzeka, okudinga ukuhlaziywa okuphelele.
Ama-granite rulers avame ukusetshenziswa ku-metrology ngenxa yokuqina kwawo kanye nokumelana nokuguquguquka. Ahlinzeka ngobuso obuyisicaba nobuzinzile obubalulekile ekulinganisweni okunembile. Kodwa-ke, izici eziningana zingaba nomthelela emaphutheni okulinganisa lapho kusetshenziswa i-granite rule. Lokhu kufaka phakathi izimo zemvelo, ubuchwepheshe bomsebenzisi, kanye nemikhawulo engokwemvelo yamathuluzi okulinganisa ngokwawo.
Izici zemvelo ezifana nokushintshashintsha kwezinga lokushisa kanye nomswakama kungathinta ubukhulu bombusi kanye namathuluzi okulinganisa. Isibonelo, ukwanda kokushisa kungaholela ezinguqukweni ezincane kubude bombusi, okungase kuholele ekufundweni okungalungile. Ngaphezu kwalokho, uthuli noma imfucumfucu ebusweni bombusi kungaphazamisa inqubo yokulinganisa, okuholela ekungavumelani okwengeziwe.
Indlela yomsebenzisi nayo idlala indima ebalulekile ephutheni lokulinganisa. Ukucindezela okungaguquki okusetshenziswa ngesikhathi sokulinganisa, ukuhlelwa okungafanele kwethuluzi lokulinganisa, noma amaphutha e-parallax konke kungabangela ukungalungi. Ngakho-ke, kubalulekile ukuthi abasebenzisi baqeqeshwe ngezindlela zokulinganisa ezifanele ukuze banciphise la maphutha.
Ukuze kwenziwe ukuhlaziywa okuphelele kwamaphutha okulinganisa umbusi we-granite, umuntu kumele acabangele amaphutha ahlelekile nangahleliwe. Amaphutha ahlelekile avame ukutholakala futhi alungiswe, kuyilapho amaphutha angahleliwe edinga izindlela zezibalo ukuze kulinganiswe umthelela wawo ekuthembekeni kokulinganisa.
Ekuphetheni, nakuba ama-granite rulers ephakathi kwamathuluzi athembekile kakhulu okulinganisa okunembile, ukuqonda nokuhlaziya amaphutha okulinganisa kubalulekile ekufinyeleleni izinga eliphezulu lokunemba. Ngokubhekana nezici zemvelo, ukucwengisisa amasu abasebenzisi, nokusebenzisa izindlela zezibalo, umuntu anganciphisa kakhulu amaphutha okulinganisa futhi athuthukise ukuthembeka kwemiphumela etholwe ngama-granite rulers.
