H Beam (HEA HEB) oo leh EN H-qaabeeya Cabbirrada Birta
HABKA SOO SAARIDA WAX soo saarka
Habka wax soo saarka ee birta heerka H-qaabeeya ee dibadda ah sida caadiga ah waxaa ka mid ah tallaabooyinka ugu muhiimsan ee soo socda:
Diyaarinta walxo ceeriin: Walxaha ceeriin ee lagu soo saaro birta qaabeysan ee H sida caadiga ah waa birta birta ah. Mashiinka birta ah wuxuu u baahan yahay in la nadiifiyo oo la kululeeyo si loo habeeyo loona sameeyo.
Habaynta rog-rogista kulul: birta hore loo sii kululeeyay waxa loo diraa warshada duubista kulul si loogu habeeyo. Warshada rogrogmada leh ee kulul, birta birta ah waxaa lagu rogrogaa rollers badan oo si tartiib tartiib ah loo sameeyay qaabka iskutallaabta ee birta H-qaabeeya.
Shaqada qabow (ikhtiyaar): Xaaladaha qaarkood, si loo hagaajiyo saxnaanta iyo tayada dusha sare ee birta H-qaabeeya, birta kulul ee H-qaabeeya ayaa sidoo kale lagu shaqeyn doonaa qabow, sida duubista qabow, sawir, iwm.
Goynta iyo dhamaystirka: Ka dib shaqo rogid iyo qabow, birta H-qaabeeya waxay u baahan tahay in la gooyo oo la dhammeeyo si waafaqsan shuruudaha macaamilka si loo buuxiyo shuruudaha cabbirka iyo dhererka gaarka ah.
Daaweynta dusha sare: Nadiifinta iyo daaweynta ka-hortagga miridhku ee birta H-qaabaysan si loo hubiyo tayada dusha sare iyo caabbinta daxalka ee alaabta.
Kormeerka iyo baakaynta: Samee kormeer tayo leh birta H-qaabeeya ee la soo saaray, oo ay ku jiraan kormeerka tayada muuqaalka, saxnaanta cabbirka, qalabka makaanikada, iwm. Ka dib marka la gudbo imtixaanka, waa la buuxin doonaa oo diyaar u ah in loo diro macaamilka.
