Ama-rula esikwele se-granite angamathuluzi abalulekile kubunjiniyela bokunemba kanye ne-metrology, aziwa ngokuqina kwawo kanye nokumelana nokukhula kokushisa. Ukuqinisekisa ukusebenza kwawo kahle, kubalulekile ukwenza indlela yokuhlola ukunemba eqinisekisa ukunemba kwawo kanye nokuthembeka kwawo.
Indlela yokuhlola ukunemba kwerula lesikwele legranite ivame ukuhilela izinyathelo eziningana ezibalulekile. Okokuqala, irula kumele ihlanzwe kahle ukuze kususwe noma yiluphi uthuli noma imfucumfucu engathinta imiphumela yokulinganisa. Uma selihlanziwe, irula libekwa endaweni eqinile, engenazo izithingithingi ukuze kuncishiswe amathonya angaphandle ngesikhathi sokuhlolwa.
Indlela eyinhloko yokuhlola ukunemba kwerula lesikwele segranite ukusebenzisa ithuluzi lokulinganisa elilinganisiwe, njenge-dial gauge noma i-laser interferometer. Irula libekwe ngama-engeli ahlukahlukene, futhi izilinganiso zithathwa ezindaweni eziningi ngobude balo. Le nqubo isiza ekuboneni noma yikuphi ukuphambuka kuma-engeli alindelekile, okungabonisa ukuguguleka noma amaphutha okukhiqiza.
Enye indlela yokuhlola ukunemba ephumelelayo ihilela ukusetshenziswa kwepuleti lokubhekisela. Irula lesikwele legranite lihambisana nepuleti lokungaphezulu, futhi kuthathwa izilinganiso ukuze kuhlolwe ubucaba kanye nobucaba berula. Noma yikuphi ukungafani kulezi zilinganiso kungagqamisa izindawo ezidinga ukulungiswa noma ukulinganiswa kabusha.
Ngaphezu kwalokho, kubalulekile ukubhala phansi konke okutholakele ngesikhathi sokuhlola ukunemba. Lo mbhalo usebenza njengerekhodi lokubhekisela esikhathini esizayo futhi usiza ukugcina ubuqotho benqubo yokulinganisa. Ukuhlolwa njalo nokugcinwa kwe-granite square rulers akuqinisekisi nje kuphela ukunemba kwazo kodwa futhi kwandisa isikhathi sokuphila kwazo, okwenza zibe yimpahla ebalulekile kunoma iyiphi indawo yokulinganisa ukunemba.
Ekuphetheni, indlela yokuhlola ukunemba kwabalawuli besikwele begranite iyinqubo ebalulekile eqinisekisa ukuthembeka kwala mathuluzi ezinhlelweni ezahlukahlukene. Ngokulandela izinqubo zokuhlola ezihlelekile, abasebenzisi bangaqinisekisa ukuthi abalawuli babo besikwele begranite bahlala benembile futhi besebenza kahle iminyaka ezayo.
