1. Ukuma okuthe nkqo kwecala lomphetho othe nkqo nxamnye nomphezulu wokusebenza: Beka umphetho othe nkqo wegranite kwipleyiti ethe tyaba. Dlulisa i-dial gauge, exhotyiswe ngesikali esingu-0.001mm, kwibha ejikelezileyo eqhelekileyo kwaye uyibeke kwi-zero kwisikwere esiqhelekileyo. Emva koko, ngokufanayo, beka i-dial gauge kwicala elinye lomphetho othe nkqo. Ukufundwa kwe-dial gauge yimpazamo yokuma okuthe nkqo kwelo cala. Ngokufanayo, vavanya impazamo yokuma okuthe nkqo kwelinye icala, kwaye uthathe impazamo ephezulu.
2. Umlinganiselo Wendawo Yoqhagamshelwano lweParallel Straightedge: Faka isixhobo sokubonisa kumphezulu wokusebenza we-straightedge eza kuvavanywa. Gaya umphezulu kwipleyiti yesinyithi esityhidiweyo okanye umphetho ochanekileyo ubuncinane obufanayo ukuze utyhile iindawo zoqhagamshelwano ezahlukeneyo kumphezulu wokusebenza. Emva koko, beka iphepha elibonakalayo (njengephepha le-plexiglass) elinezikwere ezincinci ezingama-200 ze-2.5mm x 2.5mm, ezilinganisa i-50mm x 25mm, nakweyiphi na indawo kumphezulu wokusebenza we-straightedge eza kuvavanywa. Jonga umlinganiselo wendawo yesikwere ngasinye equlethe iindawo zoqhagamshelwano (kwiiyunithi ze-1/10). Bala isixa seemilinganiselo ezingentla kwaye wahlule ngo-2 ukuze ufumane umlinganiselo wendawo yoqhagamshelwano yendawo evavanyiweyo.
Okwesithathu, xhasa irula ehambelanayo ngeebhloko ezilinganayo eziphakamileyo kumanqaku axhasayo aqhelekileyo angama-2L/9 ukusuka kwisiphelo ngasinye serula. Khetha ibhulorho yokuvavanya efanelekileyo ngokusekelwe kubude bomphezulu wokusebenza werula (ngokubanzi amanyathelo asi-8 ukuya kwi-10, kunye nobubanzi obuphakathi kwama-50 nama-500mm). Emva koko, beka ibhulorho kwelinye icala lerula kwaye uqinise i-reflector okanye inqanaba layo. Hambisa ibhulorho kancinci kancinci ukusuka kwelinye icala lerula ukuya kwelinye, uhambisa ububanzi ngabunye ukusuka kwi-autocollimator ene-graduation ye-1″ (okanye i-0.005mm/m) okanye inqanaba le-elektroniki eline-graduation ye-0.001mm/m (kubude bomphezulu osebenzayo obungaphezulu kwe-500mm, irula yeKlasi yoku-1 ene-graduation ye-0. Ukufundwa kule ndawo kungathathwa ngenqanaba elihambelanayo le-0.01mm/m (inqanaba lohlobo lwesakhelo eline-graduation ye-0.02mm/m lingasetyenziselwa inqanaba lesi-2). Umahluko phakathi kokufundwa okuphezulu kunye nokuncinci yimpazamo yokuthe tye yomphezulu osebenzayo wenqanaba. Kuyo nayiphi na i-200mm yomphezulu osebenzayo, impazamo yokuthe tye ingamiselwa kusetyenziswa ipleyiti yebhulorho ye-50mm okanye ye-100mm, kusetyenziswa le ndlela ingentla.
IV. Ukuhambelana kweendawo zokusebenza eziphezulu nezisezantsi, kunye nomphezulu wokusebenza kunye nomphezulu wokuxhasa osezantsi, kwinqanaba elilinganayo. Ukuba ipleyiti ethe tyaba efanelekileyo ayifumaneki, icala lenqanaba linokubekwa kumphezulu wokuxhasa kwaye umahluko wokuphakama kwenqanaba ulinganiswe kusetyenziswa i-lever micrometer ene-graduation ye-0.002mm okanye i-micrometer ene-graduation ye-0.002mm.
