Iyini ibanga lokulinganisa kanye nesilinganiso sokujika?
Ibanga lokulinganisa liyinani lomehluko phakathi kwemikhawulo ephezulu nephansi yebanga elijwayelekile lethuluzi. Uma umkhawulo ophansi wokulinganisa ithuluzi ungo-zero, khona-ke inani eliphakeme lenani elibonakalayo elingalinganiswa lilingana nebanga lalo lokulinganisa. Isibonelo, ibanga lokulinganisa le-ammeter liyinani eliphakeme lamanje elingalinganiswa. Isilinganiso sokunciphisa amandla yisilinganiso sebanga lokulinganisa eliphezulu kuya ebangeni lokulinganisa eliphansi lethuluzi. Isilinganiso esikhulu sokunciphisa amandla sinikeza indawo eyengeziwe yokulungisa. Lapho izimo zenqubo zishintsha, kulula ukushintsha ibanga lokulinganisa lethuluzi ngaphandle kokushintsha ithuluzi. Kunganciphisa nenani lezinsimbi ezisele ezikhona esitokweni, okuzuzisayo ekuphathweni futhi kuvimbele ukusilela kwemali. Ngakho-ke, isilinganiso sokunciphisa amandla sethuluzi lokudlulisa amandla siyinkomba yobuchwepheshe ebaluleke kakhulu. Lapho ukhetha ithuluzi, akukhona ukuthi uma isilinganiso sokunciphisa amandla sikhulu, kungcono ukusebenza kwethuluzi. Kukhona nomqondo webanga lokusebenza. Isibonelo, kumthumeli wokucindezela onebanga lokulinganisa elingu-0-250 kPa, lapho ingcindezi yangempela esiyilinganisayo ingu-60 kPa, ibanga lokulinganisa okufanele silikhethe lingu-0-100 kPa, futhi leli banga lokulinganisa liyibanga lokusebenza. Uma isilinganiso sokujika salo mthumeli wokucindezela singu-10:1, kusho ukuthi, ngenkathi kuqinisekiswa ukunemba kwalo mthumeli wokucindezela, ibanga lokusebenza elincane esingalikhetha lingu-0-25 kPa. Uma ibanga lokusebenza lincane kunaleli nani, ukunemba kwethuluzi kuzoncipha; kanti uma ibanga lokusebenza liphakathi kuka-0-25 kPa no-0-250 kPa, ukunemba kwethuluzi kungaqinisekiswa. Ngakho-ke, ibanga lokusebenza kanye nebanga lokulinganisa eliphezulu akufanele lihluke kakhulu, ngaphandle kwalokho ukunemba kwethuluzi kuzoncipha. Kumamitha amanzi abandayo, isilinganiso sokujika siyisilinganiso sokugeleza okulinganiselwe (Q3) nokugeleza okuncane (Q1), futhi singamelwa uhlamvu "R" olulandelwa inombolo.
