I.Kwitegura ikizamini
1. Ubunini bw'icyitegererezo cyateguwe bugomba kuba inshuro zitari munsi y'ubujyakuzimu bw'icyitegererezo (ubusanzwe ni ≥10mm) kugira ngo hirindwe ko icyikitegererezo kitajya mu cyitegererezo cyangwa ngo gikorwe n'inkunga y'ubuso bwo hasi.
2. Ambara uturindantoki mu gihe ukoresha kugira ngo wirinde ko intoki zigera ku rundi ruhande n'aho icyitegererezo gikorerwa, bishobora gutera umwanda cyangwa gushwanyagurika.
3. Niba ingero zitandukanye zigomba gutandukanywa, shyira akamenyetso ku mibare y’uruhererekane ku buso butari ubwo gupima kugira ngo hirindwe ko hagira ikintu kibangamira agace k’aho amazi anyura.
4. Menya neza ko ibikoresho by'icyitegererezo bihuye n'ibikoresho byo mu gice cy'imbere (urugero, igipimo cya tungsten carbide kirakenewe ku bikoresho bikomeye cyane) kugira ngo hirindwe kwangirika cyane kw'igice cy'imbere cyangwa gucika kw'icyitegererezo.
II. Uburyo bwo gukora
1. Gutangiza ibikoresho no kwisuzuma
Nyuma yo kwemeza ko umugozi w'amashanyarazi w'ibikoresho uhujwe neza, uwushyire mu gikoresho cy'amashanyarazi cya 220V, 50/60Hz hanyuma ufungure switch y'inyuma y'amashanyarazi. Ibikoresho bizakora isuzuma ryigenga, ecran yo kwerekana izacana kandi yerekane aho ikorera mbere. Nyuma yo kurangiza isuzuma ryigenga, ibikoresho bizahita byinjira mu buryo bwikora kandi byinjire mu gihe cyo gutegereza kugira ngo bikore.

2. Gushyiraho no gushyiraho Indenter
Ukurikije imiterere y'ibikoresho bizageragezwa, hitamo agace k'umupira karimo sima gafite ingano ikwiye (φ2.5, 5, 10 mm). Sukura amavuta arwanya ingese ukoresheje alukolo hanyuma uhanagure neza ukoresheje igitambaro gisukuye cya kotoni. Shyiramo agace k'imbere mu mwobo w'ipamba hanyuma uzengurutse vis yo gufata kugira ngo ihuze n'igice cy'inyuma cy'inyuma, urebe neza ko gashyirwamo neza. Hanyuma hitamo urubuga rwo kugerageza (urubuga runini rurerure, urubuga ruto rurerure, urubuga rufite ishusho ya V) ukurikije imiterere y'icyitegererezo, shyira icyitegererezo neza kandi neza, kandi urebe neza ko ubuso bwacyo busukuye kandi budafite umwanda.
3. Guhitamo imbaraga no kuzishyiraho mu igerageza
Igipimo cy’ubukana bwa Brinell cya HB-3000C gitanga imbaraga 10 z’igerageza (kuva kuri 612.9 N kugeza kuri 29421 N). Umukoresha ashobora guhitamo imbaraga zikenewe kuri ecran ya santimetero 8 akurikije ibisabwa mu isuzuma, kandi umukoresha azashyiraho uburemere bwe kugira ngo agere ku mbaraga z’igerageza.
Hagati aho, igihe cyo guhagarara gishobora gushyirwa hagati y'amasegonda 0 na 60 kuri ecran ikoraho hashingiwe ku miterere y'ibikoresho. Ku bikoresho rusange, igihe cyo guhagarara cyasabwe ni amasegonda 10-15.
4. Ikizamini cy'Ubukomere bwa Brinell
Shyira igikoresho cyo gukora ku ntebe y'akazi, hanyuma uzunguruke urutoki rw'intoki mu buryo bw'isaha ku muvuduko uhamye kandi uhuye kugira ngo uzamure icyiciro cy'icyitegererezo. Hagarika kuzenguruka ako kanya igihe ijwi ryumvikana iyo icyitegererezo gihuye n'igice cyo gukoraho.
Umupimi azatangiza ikizamini mu buryo bwikora, kirimo gushyiramo, gufata no gusohora imbaraga z'ikizamini nyamukuru mu buryo bukurikiranye kugira ngo hakorwe akantu ko guhagarara. Hanyuma uzengurutsa urukiramende rw'intoki mu buryo bunyuranyije n'isaha kugira ngo umanure icyiciro cy'icyitegererezo hanyuma ukureho icyitegererezo cyapimwe.
5. Igipimo cy'ubukomere bwa Brinell
Kuraho icyitegererezo, aho hazagaragara akadomo k'uruziga. Pima umurambararo w'akadomo k'uruziga ukoresheje mikorosikopi ya 20×, hanyuma shyira agaciro kapimwe mu gice cya hB-3000C Brinell Hardness Tester. Sisitemu izahita ibarura agaciro k'ubukomere hashingiwe ku buryo bwateguwe.
Ubundi buryo, hari uburyo bwo gupima bwa Brinell. Ubu buryo bufata ishusho y’aho ibintu bigeze hakoreshejwe sensor ya CCD, maze agaciro k’ubukana kagapimwa kandi kakagaragazwa na mudasobwa.
6. Kwandika amakuru no gukora raporo
Nyuma y’uko ikizamini kirangiye, umukozi ashobora kureba amakuru arambuye kuri ecran, harimo agaciro k’ubukomere, uburebure bw’umurambararo, n’amakuru y’ibarurishamibare (agaciro ntarengwa, agaciro ntarengwa, agaciro mpuzandengo, nibindi). Amakuru ashobora kubikwa mu bubiko bw’imbere bw’ikizamini cyangwa mu gikoresho cyo hanze cya USB.
Byongeye kandi, porogaramu igerageza ishobora gukora raporo ya Word irimo amakuru y’ibipimo, ibisubizo by’ibarurishamibare n’amashusho, ashobora gucapwa cyangwa koherezwa mu mahanga n’umukoresha.
III.Kubungabunga no Kwirinda
1.Ikizamini kirangiye, rekura imbaraga zose z'ikizamini, hitamo uburyo bwo kuzimya kuri ecran, hanyuma uzimye switch y'amashanyarazi y'ibikoresho.
2. Niba ibikoresho bitagomba gukoreshwa igihe kirekire, kuraho insinga y'amashanyarazi, ukuremo ibice nk'agakoresho ko gushyiramo ibintu n'ibiremereye, ubisukure neza, hanyuma ubibike neza ahantu habigenewe kugira ngo wirinde kwangirika cyangwa gutakaza.
3. Kora isuku no kubungabunga ibikoresho buri gihe. Suzuma uko ibice birimo igice cyo hejuru n'ibiremereye byangiritse, kandi usimbuze ibice byangiritse cyangwa byashaje cyane ku gihe. Komeza ahantu igikoresho gikorera hasukuye kandi humye kugira ngo wirinde kwangirika guterwa n'umukungugu, ubushuhe, cyangwa ibindi bintu bihumanya.
4. Ambara ibikoresho byo kwirinda (urugero: amadarubindi y'umutekano n'uturindantoki) mu gihe cyo kubaga kugira ngo wirinde imvune z'umuntu zishobora guterwa n'impanuka.
5. Koresha ibikoresho hakurikijwe amabwiriza agenga imikorere. Ntugahindure uko ubyishakiye imiterere y'ibipimo cyangwa uburyo imikorere y'ibikoresho, kugira ngo umenye neza kandi wizewe ibisubizo by'ibizamini.
6. Mu gihe ibikoresho byangiritse cyangwa ibintu bidasanzwe, hagarika akazi ako kanya hanyuma uhagarike amashanyarazi, hanyuma uhamagare abakozi b'inzobere mu kubungabunga kugira ngo bagenzure kandi basane.
