Ehara te turanga karāhe i te tūāpapa noa iho; koia te turanga pumau mō te ine ine tino tika, ngā taputapu mīhini, me ngā pūnaha whatu matatau. Nā tōna pumau ā-roto, tōna pakeketanga pai, me te iti rawa o te horapa wera, ka taea te whakarite kia tutuki te tika o te taumata nanometer ahakoa te nui o te karāhe pango (≈3100 kg/m³), ahakoa te pumau rawa. Heoi, ahakoa te turanga tino pumau, me tino tupato, me te piri ki ngā tikanga tino pakari kia mau tonu ai tōna mahi whaimana puta noa i tōna roanga ora.
Ko te whakatutukitanga o te tika pumau ka tīmata mā te tāutanga me te whakahaere taiao. Me tino pakari, kia taurite, kia kore hoki he āputa taumahatanga ā-rohe te papa e tū ai te turanga o te karāhe. Mā te kore taurite, te kore pumau rānei o te turanga ka puta he taumahatanga kore ōrite ki roto i te karāhe, ka whakararu i tōna papatahi me tōna pumau—he āhuatanga e āta whakaitihia ana e mātou i roto i ā mātou ake whare huihuinga e whakahaeretia ana e te 10,000 m². Hei tāpiri, me whakahaere te taiao tonu. Mā te nui o te makuku ka hua ake he whānui haere i roto i te hanganga moroiti o te kohatu, ka puta pea he rerekētanga, ko te tata ki ngā pūtake wera, ki ngā papa hiko kaha rānei ka taea te whakararu i ngā taputapu e mau ana ki te turanga. Ko te mahi tino pai me whai wāhi maroke, he pai te hauhautanga me te iti o te piki me te heke o te pāmahana.
I roto i ngā mahi o ia rā, he mea nui te whakahaere tupato. He mea hanga ngā turanga karāhe kia pumau, kia hihiri hoki i raro i ā rātou kawenga kua whakatauria, engari kāore e ātete ki te tukino. Me piri tonu ngā kaiwhakahaere ki te rohe kawenga kua tohua e te turanga, me te whakarite kia tohatohahia te taumaha kia ōrite hei ārai i te piko ā-rohe, i ngā pakaru ahotea rānei ka tūpono ki ngā taputapu kua tāutahia. Ko te taka o ngā taputapu, te pānga koi, te whakatakoto rānei i ngā mea taumaha ki ngā taha ka pā kino ki te āhua o te mata kua tino pai. Mena me neke te turanga karāhe nui, me whakamahi noa i ngā taputapu motuhake kua whakatauria te kawenga, me te neke āta haere me te āta whakaaro kia kore ai e ru. Whai muri i te nekenga, me whai i tētahi tukanga whakatikatika me te whakataurite kia whakahokia mai ai te pumau o te turanga.
Me tino tika te tikanga tiaki me te horoi hei tiaki i te mata kua whakatikatikaina. Me whakamahi noa i te kakahu ngohengohe, maroke hei horoi i te puehu auau. He mea nui, ko ngā kai horoi kore-waikura anake—he mea hanga mō te karāhe—me whakamahi tonu hei tango i ngā toenga uaua. Ka taea e ngā matū waikawa, kawakore rānei te haehae i te mata kua tino orohia, ka whakangaro i te whakaotinga tino tika. Heoi anō, he mea nui te tiaki i te kino tinana; kaua rawa e tōia ngā taputapu whakarewa, ngā tirotiro, ngā wahi mahi rānei ki runga i te mata. Mō ngā wāhi e whakamahia nuitia ana, e whakatakotoranga pinepine ana rānei i ngā wāhanga, ko te whakamahi i ngā papa urunga kore-waikura he huarahi māmā engari he whai hua hei ārai i ngā karawarawa moroiti, kia mau tonu ai te āhua o te turanga e hiahiatia ana mō te tiwhikete Tohu 00/0.
Hei whakamutunga, ko te pumau mō te wā roa o te turanga karāhe e whakawhirinaki ana ki tētahi kaupapa whakatikatika pakari. Ahakoa he pai ake te pumau o te karāhe i te rino, ka heke haere te tika o te mata i te pakaru noa me ngā huringa iti o te taiao. I runga i te kaha o te whakamahinga me te taumata tika e hiahiatia ana, me mahi ngā tirotiro ā-wā - ko te tikanga ia toru marama ki te tau - e ngā tohunga hangarau ine ine whaimana e whakamahi ana i ngā taputapu tino tika, pērā i ngā Renishaw Laser Interferometers, i ngā WYLER Electronic Levels rānei. He mea nui ngā tuhinga whānui o ēnei rā whakatikatika, raraunga, me ngā mahi whakatikatika hei pupuri i te whai i te turanga me te whakaatu i tōna pai tonu mō ngā mahi tino tika e tautokona ana e ia. Mā te piri ki ēnei tikanga whakahaere tino pakari, ka taea e ngā kaiwhakamahi te whakamahi katoa i te pumau o tētahi ZHHIMG® Granite Base, me te whakarite kia mau tonu tā rātou whakapau kaha ki te tika.
