Ochwepheshe abaningi ekukhiqizeni ngokunemba babhekene nenkinga enzima: amapulatifomu okubhekisela asanda kwamukelwa alahlekelwa kancane kancane ukuba yisicaba futhi aqhubeke nokunemba ngemva kokufakwa, okudinga ukugaya kabusha efektri. Ukonakala okunjalo kokunemba akuvamile ukubangelwa ukuguguleka kwansuku zonke. Kuvela ikakhulukazi ekukhishweni kancane kokucindezeleka kwangaphakathi okusele okufihliwe ngaphakathi kwezingxenye, okuhlanekezela ubuso bokubhekisela. Phakathi kwabathwali bezinkomba ezahlukene ze-metrology, amapuleti obuso be-granite agwema ngempumelelo ukuguquka okubangelwa ukukhishwa kokucindezeleka ngenxa yokucindezeleka kwangaphakathi okuphansi. Uma esefakwe ngomshini, angagcina ukunemba okuphezulu isikhathi eside futhi asebenze njengereferensi ekhethwayo ye-metrology ezinzile yesikhathi eside.
Ukucindezeleka kwangaphakathi kungukucindezeleka okungabonakali okubanjwe ngaphakathi kwezinto. Izingxenye zensimbi ezifana nensimbi ephonswe kanye nensimbi ziqoqa kalula ukucindezeleka okukhulu okusele ngesikhathi sokubumba, ukuhlanganisa nokusika. Ngisho nangemva kokwelashwa kokuguga ngaphambi kokulethwa, ukucindezeleka kwangaphakathi akunakuqedwa ngokuphelele. Kuzokhululwa kancane ngaphansi kokushintshashintsha kwezinga lokushisa, umthwalo oqhubekayo kanye nokubekwa okuhlala isikhathi eside, okubangela ukugoba okuncane okungabonakali. Ekuhlolweni kokunemba kwezinga elincane kanye ne-nano, ukuguquguquka okuncane kungaphazamisa indiza yokubhekisela futhi kubangele ukuzulazula okuqhubekayo kwedatha elinganisiwe, okuholela ekulinganisweni okuvamile kanye nokuvuselelwa, okuphakamisa izindleko zokusebenza. Ama-gauge amatshe abiza kancane anezingozi ezifanayo: itshe elisezingeni eliphansi liqoqa ukucindezeleka okukhulu ngesikhathi sokumba nokusika. Nakuba ukunemba kwawo kubonakala kufanelekile ngesikhathi esifushane, ukuguquguquka kuvela ngemva kwezinyanga zokubekwa kanye nokunemba kwehla ngokushesha.
Amabhulokhi aluhlaza e-granite asezingeni eliphezulu akhethwa ngokucophelela. Idwala liye labhekana nokuguga kwemvelo kwemvelo eminyakeni eyizigidi, kanti ukucindezeleka kwangaphakathi kokuqala kukhishwa ngokuphelele. Itshe elingavuthiwe lizodlula ekucwilisweni okuqinile ngemva kokumba nokusika. Amabhulokhi amakhulu agcinwa egcekeni lamatshe ukuze ukucindezeleka okusha okudalwe ngesikhathi sokusika kunyamalale kancane ngaphambi kokugaya. Lokhu kubalulekile emikhiqizweni eqediwe ephansi kokucindezeleka, kunciphisa izingozi zokuguquka kusengaphambili. Amabhulokhi kuphela anesimo esizinzile kanye nokukhululeka kokucindezeleka okufanelekile adluliselwa endaweni yokusebenzela yokushisa engaguquki ukuze kugaywe kahle.
Izinqubo zomshini nazo zenzelwe ukulawula ukucindezeleka. Emishinini eqinile, itshe eliningi lisuswa kancane kancane ukuze kuvinjelwe ukuqongelela kokucindezeleka okusha ekusikeni okunzima okukodwa. Izikhawu zokuzinza ezimile zigcinwa phakathi kokudlula kokugaya ukuze kulinganiswe isimo sangaphakathi ngaphambi kokucutshungulwa okwengeziwe. Ukuqeda kuqedwa endaweni yokusebenzela ehlala njalo yokushisa kanye neyokudlidliza ukuze kugwenywe ukucindezeleka okwengeziwe okubangelwa umehluko wokushisa. Ngemva kokuba ukugaya kufinyelela ekuthambekeni okuqondiwe, amapuleti aqediwe agcinwa ukuze kubhekwe ngokuma ukuze kulandelwe izinguquko zokuthambekela. Imikhiqizo ivunyelwe ukupakishwa futhi ithunyelwe kuphela ngemva kokuqinisekiswa ukuthi akukho ukuguquka okuvela ekukhululweni kokucindezeleka okuhamba kancane. 
Inzuzo esobala kakhulu yezici ezingenakucindezeleka ukugcinwa kokunemba kwesikhathi eside. Uma ipuleti lobuso le-granite elinokucindezeleka okuphansi selifakwe emshinini kuze kube sesimweni sokugcina, i-geometry yalo yokubhekisela ihlala izinzile amashumi eminyaka ngaphandle kokulayishwa ngokweqile noma umthelela omkhulu. Ukunemba kuyawohloka kancane kakhulu. Uma kuqhathaniswa namapulatifomu ensimbi nama-gauge amatshe aphansi, kudinga ukulungiswa kabusha okuncane kakhulu nokugaya kabusha futhi kugcina ukusebenza kwe-metrology okuqhubekayo. Kumalabhorethri e-metrology, amapulatifomu ocwaningo lwaseyunivesithi kanye neziteshi zokulinganisa ze-semiconductor ezifuna izinkomba ezizinzile zesikhathi eside, lawa mapuleti e-granite anciphisa ukushintshwa kwe-gauge kanye nesikhathi sokungasebenzi sokuqinisekiswa kabusha, ukuqinisekisa idatha eqhubekayo nethembekile yokukhiqiza nokucwaninga.
Ezimbonini ezisebenza ngokunemba okukhulu, ukuthembeka kwesilinganiso sokubhekisela akugcini nje ngokunemba lapho kulethwa, kodwa futhi nangokuzinza kwayo eminyakeni noma amashumi eminyaka kamuva. Ukususa ukucindezeleka kwangaphakathi kusho ukususa usongo olufihliwe lwesikhathi eside lokunemba. I-ZHHIMG isungula umsebenzi ogcwele wokulawula ukucindezeleka ohlanganisa ukukhethwa kwezinto zokusetshenziswa, ukugcinwa kwamatshe, imishini ehleliwe kanye nokubuka ngemuva kokukhiqiza. Lokhu kugcina amapuleti ongaphezulu e-granite engenakuguqulwa okubangelwa ukucindezeleka kwangaphakathi. Ngezakhiwo ze-substrate ezizinzile, amapuleti agcina ukunemba okuphezulu ngemva komshini. Ngokulandela inqubomgomo yekhwalithi yokuthi akukho mfuneko eqinile kakhulu kubunjiniyela bokunemba, i-ZHHIMG inikeza izinkomba ze-metrology ezizinzile ezihlala isikhathi eside embonini yomhlaba wonke yokunemba okukhulu.
