Qhov loj yog hais txog qhov kev ncua deb tshaj plaws ntawm ob lub ntsiab lus ntawm lub pob qhov chaw, raws li ntsuas los ntawm ob daim phiaj sib luag hauv kev sib cuag nrog lub npoo.Qhov pib loj yog lub pob nominal, uas yog lub nominal, lossis theoretical, pob kab.Lub pob loj yog ces txiav txim siab los ntawm kev ntsuas lub pob txoj kab uas hla variation, uas yog qhov txawv ntawm qhov loj tshaj plaws thiab qhov tsawg tshaj plaws txoj kab uas hla ntsuas.Rau ib tug muab ntau muaj ntau txoj kab uas hla variation, uas yog qhov txawv ntawm qhov nruab nrab txoj kab uas hla ntawm lub pob loj tshaj plaws thiab lub pob me tshaj ntawm ntau.
Sphericity, los yog sib txawv ntawm daim ntawv kheej kheej, hais txog ntau npaum li cas lub pob deviates los ntawm tus kheej kheej kheej (tawm ntawm roundness).Qhov no yog ntsuas los ntawm rotating ib lub pob tawm tsam ib tug linear transducer nrog ib tug gauge quab yuam ntawm tsawg tshaj li 4 grams (0.14 oz).Cov txiaj ntsig polar graph yog ces circumscribed nrog lub voj voog me tshaj plaws thiab qhov txawv ntawm lub voj voog ncig thiab lub pob nominal txoj kab uas hla yog qhov txawv.
