Mabda'a asaasiga ah ee ka dambeeya go'aaminta dhumucda substrate ee xaashida midabada leh waa in marka hore la cabbiro wadarta dhumucda, ka dibna laga gooyo dhumucda daahan ee la yaqaan si loo soo saaro dhumucda substrate-ka dhabta ah. Habka Micrometer-ka (taas oo ah habka ugu fudud oo ku habboon kormeerka goobta) ayaa loo adeegsaday ujeedadan. Tani waxay u adeegtaa sida habka caadiga ah ee loo isticmaalo qiimaynta goobta ee degdega ah, iyo sidoo kale nidaamka kormeerka caadiga ah ee lagu taliyay halbeegyada qaranka: Cabbirka wadarta dhumucda: Isticmaalka micrometer dibadda ah oo sax ah oo aan ka yarayn 0.01 mm, dooro 3 ilaa 5 dhibcood cabbir oo kala duwan oo ku yaal ugu yaraan 10 mm ka fog cidhifka muunadda tijaabada. Cabbir wadarta dhumucda xaashida midabaysan mid kasta oo ka mid ah dhibcahan oo qor natiijooyinka. Kasaarida Dahaarka: Isticmaal xaashida rinjiga ama warqad ciid si aad gabi ahaanba u xoqdo ugana saarto dahaarka oo dhan meelaha cabbirka ee loo qoondeeyay (sii socota ilaa substrate-ka birta hoose ka muuqdo). Ka digtoonow si aad isaga ilaaliso naaxinta xad-dhaafka ah ee dami karta ama dhaawici karta substrate-ka laftiisa. Cabbirka Dhumucda Substrate-ka: Isticmaalka mikrometer isku mid ah, cabbir dhumucda substrate-ka meelaha u dhigma ee daaha laga saaray, oo qor natiijooyinka. Xisaabinta iyo Xaqiijinta: Ka jar dhumucda dahaarka wadarta dhumucda si aad u hesho dhumucda substrate-ka dhabta ah. Is barbar dhig qiimahan la xisaabiyey iyo kan magaca (la cayimay) ee qiimaha;
